Processor/Memory Subsystem

3.1 Introduction

This systems support the Intel Pentium and Core processor families and use the Q45 chipset

(Figure 3-1). These systems support PC2-6400 and PC2-5300 DDR2 memory modules. This chapter describes the processor/memory subsystem.

3.2 Intel Processors

These systems each feature an Intel processor in a FC-LGA775 package mounted with a heat sink in a zero-insertion force socket. The mounting socket allows the processor to be easily changed for upgrading.

3.2.1 Intel Processor Overview

The models covered in this guide support Intel Celeron, Pentium, and Core 2 processors, including the latest Intel Core 2 Duo, and Core 2 Quad processors.

Key features of supported Intel processors include:

Dual- or quad-core architecture—Provides full parallel processing.

Execution Trace Cache— A new feature supporting the branch prediction mechanism, the trace cache stores translated sequences of branching micro-operations (ops) and is checked when suspected re-occurring branches are detected in the main processing loop. This feature allows instruction decoding to be removed from the main processing loop.

■ Rapid Execution Engine—Arithmetic Logic Units (ALUs) run at twice (2x) processing frequency for higher throughput and reduced latency.

■ Up to 12-MB of L2 cache—Using a 32-byte-wide interface at processing speed, the large L2 cache provides a substantial increase.

■ Advanced dynamic execution—Using a larger (4K) branch target buffer and improved prediction algorithm, branch mis-predictions are significantly reduced

Additional Streaming SIMD extensions (SSE2 and SSE3)—In addition to the SSE support provided by earlier processors, the latest processors include additional MMX instructions that enhance:

Streaming video/audio processing

Photo/video editing

Speech recognition

3D processing

Encryption processing

■ Quad-pumped Front Side Bus (FSB)—The FSB uses a 200-MHz clock for qualifying the buses' control signals. However, address information is transferred using a 2x strobe while data is transferred with a 4x strobe, providing a maximum data transfer rate that is four times that of earlier processors.

The Intel processor increases processing speed by using higher clock speeds with hyper-pipelined technology, therefore handling significantly more instructions at a time. The

Arithmetic Logic Units (ALUs) of all processors listed above run at twice the core speed.

Technical Reference Guide

Processor/Memory Subsystem

3.2.2 Processor Changing/Upgrading

All models use the LGA775 ZIF (Socket T) mounting socket. These systems require that the processor use an integrated heatsink/fan assembly. A replacement processor must use the same type heatsink/fan assembly as the original to ensure proper cooling. The heatsink and attachment clip are specially designed provide maximum heat transfer from the processor component.

CAUTION: Attachment of the heatsink to the processor is critical on these systems. Improper attachment of the heatsink will likely result in a thermal condition. Although the system is designed to detect thermal conditions and automatically shut down, such a condition could still result in damage to the processor component. Refer to the applicable Service Reference Guide for processor installation instructions.

Table 3-1 provides a sample listing of processors supported by these systems.

Processor/Memory Subsystem

All models support non-ECC PC2-5300 and PC2-6400 DDR2 memory. The USDT form factor supports up to eight gigabytes of memory while the SFF and CMT form factors support up to 16 gigabytes of memory.

The DDR SDRAM “PCxxxx” reference designates bus bandwidth (i.e., a PC2-5300 module can, operating at a 667-MHz effective speed, provide a throughput of 5300 MBps (8 bytes ×

667MHz)). Memory speed types may be mixed within a system, although the system BIOS will set the memory controller to work at speed of the slowest memory module.

The USDT system board provides two SODIMM sockets and the SFF and CMT system boards provide four DIMM sockets

XMM1, channel A (black)

XMM2, channel A (white, not present in USDT form factor)

XMM3, channel B (white)

XMM4, channel B (white, not present in USDT form factor)

Memory modules do not need to be installed in pairs although installation of pairs (especially matched sets) provides the best performance. The XMM1 socket must be populated for proper support of Intel Active Management Technology (AMT). The BIOS will detect the module population and set the system accordingly as follows:

Single-channel mode - memory installed for one channel only

Dual-channel asymetric mode - memory installed for both channels but of unequal channel capacities.

■ Dual-channel interleaved mode (recommended) - memory installed for both channels and offering equal channel capacities, proving the highest performance.

These systems support memory modules with the following parameters:

Unbuffered, compatible with SPD rev. 1.0

512-Mb, and 1-Gb memory technologies for x8 and x16 devices

CAS latency (CL) of 5 or 6 (depending on memory speed)

Single or double-sided

Non-ECC memory only

The SPD format supported by these systems complies with the JEDEC specification for 128-byte

EEPROMs. This system also provides support for 256-byte EEPROMs to include additional

HP-added features such as part number and serial number.

If BIOS detects an unsupported memory module, a “memory incompatible” message will be displayed and the system will halt. These systems are shipped with non-ECC modules only.

An installed mix of memory module types is acceptable but operation will be constrained to the level of the module with the lowest (slowest) performance.

If an incompatible memory module is detected the NUM LOCK will blink for a short period of time during POST and an error message may or may not be displayed before the system hangs.

HP recommends using symmetrical loading (same-capacity, same-speed modules across both channels) to achieve the best performance.

CAUTION: Always power down the system and disconnect the power cord from the AC outlet before adding or replacing memory modules. Changing memory modules while the unit is plugged into an active AC outlet could result in equipment damage.

Memory amounts over 3 GB may not be fully accessible with 32-bit operating systems due to system resource requirements. Addressing memory above 4 GB requires a 64-bit operating system.

3.3.2 Memory Mapping and Pre-allocation

Figure 3-2 shows the system memory map. The Q45 Express chipset includes a Management

Engine that pre-allocates a portion of system memory (16 MB for one module, 32 MB for two modules) for managment functions. In addition, the internal graphics controller pre-allocates a portion of system memory for video use (refer to chapter 6). Pre-allocated memory is not available to the operating system. The amount of system memory reported by the OS will be the total amount installed less the pre-allocated amount.

PCI bus overview (4.2)

System resources (4.3)

Real-time clock and configuration memory (4.4)

System management (4.5)

Register map and miscellaneous functions (4.6)

This chapter covers functions provided by off-the-shelf chipsets and therefore describes only basic aspects of these functions as well as information unique to the systems covered in this guide. For detailed information on specific components, refer to the applicable manufacturer's documentation.

4.2 PCI Bus Overview

This section describes the PCI bus in general and highlights bus implementation for systems covered in this guide. For detailed information regarding PCI bus operation, refer to the appropriate PCI specification or the PCI web site: www.pcisig.com.

These systems implement the following types of PCI buses:

PCI 2.3 - Legacy parallel interface operating at 33-MHz

PCI Express - High-performance interface capable of using multiple TX/RX high-speed lanes of serial data streams

4.2.1 PCI 2.3 Bus Operation

The PCI 2.3 bus consists of a 32-bit path (AD31-00 lines) that uses a multiplexed scheme for handling both address and data transfers. A bus transaction consists of an address cycle and one or more data cycles, with each cycle requiring a clock (PCICLK) cycle. High performance is achieved during burst modes in which a transaction with contiguous memory locations requires that only one address cycle be conducted and subsequent data cycles are completed using auto-incremented addressing.

Devices on the PCI bus must comply with PCI protocol that allows configuration of that device by software. In this system, configuration mechanism #1 (as described in the PCI Local Bus specification Rev. 2.3) is employed.

System Support

The PCI bus supports a bus master/target arbitration scheme. A bus master is a device that has been granted control of the bus for the purpose of initiating a transaction. A target is a device that is the recipient of a transaction. The Request (REQ), Grant (GNT), and FRAME signals are used by PCI bus masters for gaining access to the PCI bus. When a PCI device needs access to the PCI bus (and does not already own it), the PCI device asserts its REQn signal to the PCI bus arbiter (a function of the system controller component). If the bus is available, the arbiter asserts the GNTn signal to the requesting device, which then asserts FRAME and conducts the address phase of the transaction with a target. If the PCI device already owns the bus, a request is not needed and the device can simply assert FRAME and conduct the transaction. Table 4-2 shows the grant and request signals assignments for the devices on the PCI bus.

[2] CMT form factor only

PCI bus arbitration is based on a round-robin scheme that complies with the fairness algorithm specified by the PCI specification. The bus parking policy allows for the current PCI bus owner

(excepting the PCI/ISA bridge) to maintain ownership of the bus as long as no request is asserted by another agent. Note that most CPU-to-DRAM accesses can occur concurrently with PCI traffic, therefore reducing the need for the Host/PCI bridge to compete for PCI bus ownership.

4.2.2 PCI Express Bus Operation

The PCI Express (PCIe) v1.1 bus is a high-performace extension of the legacy PCI bus specification. The PCI Express bus uses the following layers:

Software/driver layer

Transaction protocol layer

Link layer

Physical layer

Software/Driver Layer

The PCI Express bus maintains software compatibility with PCI 2.3 and earlier versions so that there is no impact on existing operating systems and drivers. During system intialization, the PCI

Express bus uses the same methods of device discovery and resource allocation that legacy

PCI-based operating systems and drivers are designed to use.

Transaction Protocol Layer

The transaction protocol layer processes read and write requests from the software/driver layer and generates request packets for the link layer. Each packet includes an identifier allowing any required responcse packets to be directed to the originator.

Technical Reference Guide www.hp.com

4-3

System Support

Link Layer

The link layer provides data integrity by adding a sequence information prefix and a CRC suffix to the packet created by the transaction layer. Flow-control methods ensure that a packet will only be transferred if the receiving device is ready to accomodate it. A corrupted packet will be automatically re-sent.

Physical Layer

The PCI Express bus uses a point-to-point, high-speed TX/RX serial lane topology. One or more full-duplex lanes transfer data serially, and the design allows for scalability depending on end-point capabilities. Each lane consists of two differential pairs of signal paths; one for transmit, one for receive (Figure 4-1).

System Board PCI Express Card

Device A

TX

RX

Device B

Figure 4-1. PCI Express Bus Lane

Each byte is transferred using 8b/10b encoding. which embeds the clock signal with the data.

Operating at a 2.5 Gigabit transfer rate, a single lane can provide a data flow of 200 MBps. The bandwidth is increased if additional lanes are available for use. During the initialization process, two PCI Express devices will negotiate for the number of lanes available and the speed the link can operate at. In a x1 (single lane) interface, all data bytes are transferred serially over the lane.

In a multi-lane interface, data bytes are distributed across the lanes using a multiplex scheme.

4.2.3 Option ROM Mapping

During POST, the PCI bus is scanned for devices that contain their own specific firmware in

ROM. Such option ROM data, if detected, is loaded into system memory's DOS compatibility area (refer to the system memory map shown in chapter 3).

4.2.4 PCI Interrupts

Eight interrupt signals (INTA- thru INTH-) are available for use by PCI devices. These signals may be generated by on-board PCI devices or by devices installed in the PCI slots. For more information on interrupts including PCI interrupt mapping refer to the “System Resources” section 4.3.

4.2.5 PCI Power Management Support

This system complies with the PCI Power Management Interface Specification (rev 1.0). The

PCI Power Management Enable (PME-) signal is supported by the chipset and allows compliant

PCI peripherals to initiate the power management routine.

4.3 System Resources

This section describes the availability and basic control of major subsystems, otherwise known as resource allocation or simply “system resources.” System resources are provided on a priority basis through hardware interrupts and DMA requests and grants.

4.3.1 Interrupts

The microprocessor uses two types of hardware interrupts; maskable and nonmaskable. A maskable interrupt can be enabled or disabled within the microprocessor by the use of the STI and CLI instructions. A nonmaskable interrupt cannot be masked off within the microprocessor, but may be inhibited by legacy hardware or software means external to the microprocessor.

The maskable interrupt is a hardware-generated signal used by peripheral functions within the system to get the attention of the microprocessor. Peripheral functions produce a unique INTA-H

(PCI) or IRQ0-15 (ISA) signal that is routed to interrupt processing logic that asserts the interrupt (INTR-) input to the microprocessor. The microprocessor halts execution to determine the source of the interrupt and then services the peripheral as appropriate.

Most IRQs are routed through the I/O controller of the super I/O component, which provides the serializing function. A serialized interrupt stream is then routed to the ICH component.

Interrupts may be processed in one of two modes (selectable through the F10 Setup utility):

8259 mode

APIC mode

These modes are described in the following subsections.

8259 Mode

The 8259 mode handles interrupts IRQ0-IRQ15 in the legacy (AT-system) method using

8259-equivalent logic. If more than one interrupt is pending, the highest priority (lowest number) is processed first.

APIC Mode

The Advanced Programmable Interrupt Controller (APIC) mode provides enhanced interrupt processing with the following advantages:

Eliminates the processor's interrupt acknowledge cycle by using a separate (APIC) bus

Programmable interrupt priority

Additional interrupts (total of 24)

The APIC mode accommodates eight PCI interrupt signals (PIRQA-..PIRQH-) for use by PCI devices. The PCI interrupts are evenly distributed to minimize latency and wired as shown in

Table 4-5.

The PCI interrupts can be configured by PCI Configuration Registers 60h..63h to share the standard ISA interrupts (IRQn).

The APIC mode is supported by Windows NT, Windows 2000, and Windows XP, and Windows

Vista operating systems. Systems running the Windows 95 or 98 operating system will need to run in 8259 mode.

4.3.2 Direct Memory Access

Direct Memory Access (DMA) is a method by which a device accesses system memory without involving the microprocessor. Although the DMA method has been traditionally used to transfer blocks of data to or from an ISA I/O device, PCI devices may also use DMA operation as well.

The DMA method reduces the amount of CPU interactions with memory, freeing the CPU for other processing tasks. For detailed information regarding DMA operation, refer to the data manual for the Intel 82801 ICH10 I/O Controller Hub.

4.4 Real-Time Clock and Configuration Memory

The Real-time clock (RTC) and configuration memory (also referred to as “CMOS”) functions are provided by the 82801 component and is MC146818-compatible. As shown in the following figure, the 82801 ICH10 component provides 256 bytes of battery-backed RAM divided into two

128-byte configuration memory areas. The RTC uses the first 14 bytes (00-0Dh) of the standard memory area. All locations of the standard memory area (00-7Fh) can be directly accessed using conventional OUT and IN assembly language instructions through I/O ports 70h/71h, although the suggested method is to use the INT15 AX=E823h BIOS call.

Figure 4 4. Configuration Memory Map

A lithium 3-VDC battery is used for maintaining the RTC and configuration memory while the system is powered down. During system operation a wire-Ored circuit allows the RTC and configuration memory to draw power from the power supply. The battery is located in a battery holder on the system board and has a life expectancy of three or more years. When the battery has expired it is replaced with a CR2032 or equivalent 3-VDC lithium battery.

4.4.1 Clearing CMOS

The contents of configuration memory (including the Power-On Password) can be cleared by the following procedure:

1. Turn off the unit.

2. Disconnect the AC power cord from the outlet and/or system unit.

3. Remove the chassis hood (cover) and insure that no LEDs on the system board are illuminated.

4. On the system board, press and hold the CMOS clear button (switch SW50, colored yellow) for at least 5 seconds.

5. Replace the chassis hood (cover).

6. Reconnect the AC power cord to the outlet and/or system unit.

7. Turn the unit on.

To clear only the Power-On Password refer to section 4.5.1.

4.5 System Management

This section describes functions having to do with security, power management, temperature, and overall status. These functions are handled by hardware and firmware (BIOS) and generally configured through the Setup utility.

4.5.1 Security Functions

These systems include various features that provide different levels of security. Note that this subsection describes only the hardware functionality (including that supported by Setup) and does not describe security features that may be provided by the operating system and application software.

4-10 www.hp.com

Technical Reference Guide

System Support

Power-On / Setup Password

These systems include a power-on and setup passwords, which may be enabled or disabled

(cleared) through a jumper on the system board. The jumper controls a GPIO input to the 82801

ICH10 that is checked during POST. The password is stored in configuration memory (CMOS) and if enabled and then forgotten by the user will require that either the password be cleared

(preferable solution and described below) or the entire CMOS be cleared (refer to section 4.4.1).

To clear the password, use the following procedure:

1. Turn off the system and disconnect the AC power cord from the outlet and/or system unit.

2. Remove the cover (hood) as described in the appropriate User Guide or Maintainance And

Service Reference Guide. Insure that all system board LEDs are off (not illuminated).

3. Locate the password clear jumper (header is colored green and labeled E49 on these systems) and move the jumper from pins 1 and 2 and place on (just) pin 2 (for safekeeping).

4. Replace the cover.

5. Re-connect the AC power cord to the AC outlet and/or system unit.

6. Turn on the system. The POST routine will clear and disable the password.

7. To re-enable the password feature, repeat steps 1-6, replacing the jumper on pins 1 and 2 of header E49.

Setup Password

The Setup utility may be configured to be always changeable or changeable only by entering a password. Refer to the previous procedure (Power On / Setup Password) for clearing the Setup password.

Cable Lock Provision

These systems include a chassis cutout (on the rear panel) for the attachment of a cable lock mechanism.

I/O Interface Security

The SATA, serial, parallel, USB, and diskette interfaces may be disabled individually through the

Setup utility to guard against unauthorized access to a system. In addition, the ability to write to or boot from a removable media drive (such as the diskette drive) may be enabled through the

Setup utility. The disabling of the serial, parallel, and diskette interfaces are a function of the SIO controller. The USB ports are controlled through the 82801.

Chassis Security

Some systems feature Smart Cover (hood) Sensor and Smart Cover (hood) Lock mechanisms to inhibit unauthorized tampering of the system unit.

Smart Cover Sensor

These systems include a plunger switch that, when the cover (hood) is removed, closes and grounds an input of the 82801 component. The battery-backed logic will record this “intrusion” event by setting a specific bit. This bit will remain set (even if the cover is replaced) until the system is powered up and the user completes the boot sequence successfully, at which time the bit will be cleared. Through Setup, the user can set this function to be used by Alert-On-LAN and or one of three levels of support for a “cover removed” condition:

Technical Reference Guide www.hp.com

4-11

System Support

Level 0—Cover removal indication is essentially disabled at this level. During POST, status bit is cleared and no other action is taken by BIOS.

Level 1—During POST the message “The computer's cover has been removed since the last system start up” is displayed and time stamp in CMOS is updated.

Level 2—During POST the “The computer's cover has been removed since the last system start up” message is displayed, time stamp in CMOS is updated, and the user is prompted for the administrator password. (A Setup password must be enabled in order to see this option).

Smart Cover Lock (Optional)

The SFF and CMT systems support an optional solenoid-operated locking bar that, when activated, prevents the cover (hood) from being removed. The GPIO ports 44 and 45 of the SIO controller provide the lock and unlock signals to the solenoid. A locked hood may be bypassed by removing special screws that hold the locking mechanism in place. The special screws are removed with the Smart Cover Lock Failsafe Key.

4.5.2 Power Management

These systems provide baseline hardware support of ACPI- and APM-compliant firmware and software. Key power-consuming components (processor, chipset, I/O controller, and fan) can be placed into a reduced power mode either automatically or by user control. The system can then be brought back up (“wake-up”) by events defined by the ACPI 2.0 specification. The ACPI wake-up events supported by this system are listed as follows:

4.5.4 Thermal Sensing and Cooling

All systems feature a variable-speed fan mounted as part of the processor heatsink assembly. All systems also provide or support an auxiliary chassis fan. All fans are controlled through temperature sensing logic on the system board and/or in the power supply. There are some electrical differences between form factors and between some models, although the overall functionally is the same. Typical cooling conditions include the following:

1. Normal—Low fan speed.

2. Hot processor—ASIC directs Speed Control logic to increase speed of fan(s).

3. Hot power supply—Power supply increases speed of fan(s).

4. Sleep state—Fan(s) turned off. Hot processor or power supply will result in starting fan(s).

Technical Reference Guide www.hp.com

4-13

System Support

The RPM (speed) of all fans is the result of the temperature of the CPU as sensed by speed control circuitry. The fans are controlled to run at the slowest (quietest) speed that will maintain proper cooling.

Units using chassis and CPU fans must have both fans connected to their corresponding headers to ensure proper cooling of the system.

4.6.2 GPIO Functions

ICH10 Functions

The ICH10 provides various functions through the use of programmable general purpose input/output (GPIO) ports. These systems use GPIO ports and associate registers of the ICH10 for the following functions:

PCI interupt request control

Chassis and board ID

Hood (cover) sensor and lock detect

Media card reader detect

S4 state indicator

USB port over-current detect

Flash security override

Serial port detect

REQn#/GNTn# sigal control

SIO Controller Functions

In addition to the serial and parallel port functions, the SIO controller provides the following specialized functions through GPIO ports:

Power/Hard drive LED control for indicating system events (refer to Table 4-8)

Hood lock/unlock controls the lock bar mechanism

Thermal shutdown control turns off the CPU when temperature reaches certain level

Processor present/speed detection detects if the processor has been removed. The occurrence of this event will, during the next boot sequence, initiate the speed selection routine for the processor.

■ Legacy/ACPI power button mode control uses the pulse signal from the system's power button and produces the PS On signal according to the mode (legacy or ACPI) selected.

Input/Output Interfaces

5.1 Introduction

This chapter describes the standard interfaces that provide input and output (I/O) porting of data and that are controlled through I/O-mapped registers. The following I/O interfaces are covered in this chapter:

SATA/eSATA interfaces (5.2)

Diskette drive interface (5.3)

Serial interfaces (5.4)

Parallel interface support (5.5)

Keyboard/pointing device interface (5.6)

Universal serial bus interface (5.7)

Audio subsystem (5.8)

Network interface controller (5.9)

Technical Reference Guide www.hp.com

5-1

Input/Output Interfaces

These systems provide two, three, or four serial ATA (SATA) interfaces that support tranfer rates up to 3.0 Gb/s and RAID data protection functionality. The SFF and CMT form factors can also support an external SATA (eSATA) device through an optional bracket/cable assembly.

5.2.1 SATA interface

The SATA interface duplicates most of the functionality of the EIDE interface through a register interface that is equivalent to that of the legacy IDE host adapter. The ICH10 DO component includes Intel RAID migration technology that simplifies the migration from a single hard to a

RAID0 or RAID1 dual hard drive array without requiring OS reinstallation. Intel Matrix RAID provides exceptional storage performance with increased data protection for configurations using dual drive arrays. A software solution is included that provides full management and status reporting of the RAID array, and the BIOS ROM also supports RAID creation, naming, and deletion of RAID arrays.

The standard 7-pin SATA connector is shown in the figure below.

Input/Output Interfaces

5.2.2 eSATA interface

The SFF and CMT form factors provide a SATA/eSATA port (connector P64 on the system board) that can support an external SATA (eSATA) storage device. The eSATA interface provides higher bandwidth than USB 2.0 and Firewire (1394) interfaces.

An optional bracket/cable assembly (Figure 5-2) is required to attach an eSATA device to the

SFF or CMT system.

Figure 5-2. Optional eSATA Bracket/Cable Assembly.

The following operating parameters of the eSATA interface can be set in the ROM-based Setup utility:

Transfer speed: 1.5 or 3 Gbps (default set to 1.5 Gbps for reliability)

Emulation mode: IDE, AHCI, or RAID (default set to AHCI)

Port availability: Available or Hidden (default set to Available)

In the IDE or AHCI modes, the system BIOS ROM controls the hard drives and Removeable

Media Boot setting applies. In the RAID mode, the RAID option ROM controls the hard drives and the Removeable Media Boot setting does not apply.

For hot-plug functionality, the eSATA port must be set to the AHCI or RAID mode and an AHCI driver with hot-plug support must be loaded onto the system. This driver is pre-loaded on systems shipped with a Windows XP or Vista image. If the system is wiped clean or the Windows

OS is re-installed, the AHCI driver can be loaded by installing the OS while the eSATA emulation mode is set to AHCI.

Technical Reference Guide www.hp.com

5-3

Input/Output Interfaces

The SFF and CMT form factors support a diskette drive through a standard 34-pin diskette drive connector.

The diskette drive interface function is integrated into the super I/O component. The internal logic of the I/O controller is software-compatible with standard 82077-type logic. The diskette drive controller has three operational phases in the following order:

Command phase—The controller receives the command from the system.

Execution phase—The controller carries out the command.

Results phase—Status and results data is read back from the controller to the system.

The Command phase consists of several bytes written in series from the CPU to the data register

(3F5h/375h). The first byte identifies the command and the remaining bytes define the parameters of the command. The Main Status register (3F4h/374h) provides data flow control for the diskette drive controller and must be polled between each byte transfer during the

Command phase.

The Execution phase starts as soon as the last byte of the Command phase is received. An

Execution phase may involve the transfer of data to and from the diskette drive, a mechnical control function of the drive, or an operation that remains internal to the diskette drive controller.

Data transfers (writes or reads) with the diskette drive controller are by DMA, using the DRQ2 and DACK2- signals for control.

The Results phase consists of the CPU reading a series of status bytes (from the data register

(3F5h/375h)) that indicate the results of the command. Note that some commands do not have a

Result phase, in which case the Execution phase can be followed by a Command phase.

During periods of inactivity, the diskette drive controller is in a non-operation mode known as the

Idle phase.

Input/Output Interfaces

Systems covered in this guide may include one RS-232-C type serial interface to transmit and receive asynchronous serial data with external devices. Some systems may allow the installation of a second serial interface through an optional bracket/cable assembly that attaches to header

P52 on the system board. The serial interface function is provided by the super I/O controller component that includes two NS16C550-compatible UARTs.

The UART supports the standard baud rates up through 115200, and also special high speed rates of 239400 and 460800 baud. The baud rate of the UART is typically set to match the capability of the connected device. While most baud rates may be set at runtime, baud rates 230400 and

460800 must be set during the configuration phase.

The serial interface uses a DB-9 connector as shown in the following figure with the pinout listed in Table 5-4.

5.5 Parallel Interface Support

The SFF and CMT form factors include a system board header (J50) that supports an optional parallel bracket/cable assembly that provides a parallel interface for a peripheral device such as a printer. The parallel interface supports bi-directional 8-bit parallel data transfers with a peripheral device. The parallel interface supports three main modes of operation:

Standard Parallel Port (SPP) mode

Enhanced Parallel Port (EPP) mode

Extended Capabilities Port (ECP) mode

These three modes (and their submodes) provide complete support as specified for an IEEE 1284 parallel port.

5.5.1 Standard Parallel Port Mode

The Standard Parallel Port (SPP) mode uses software-based protocol and includes two sub-modes of operation, compatible and extended, both of which can provide data transfers up to

150 KB/s. In the compatible mode, CPU write data is simply presented on the eight data lines. A

CPU read of the parallel port yields the last data byte that was written.

5.5.2 Enhanced Parallel Port Mode

In Enhanced Parallel Port (EPP) mode, increased data transfers are possible (up to 2 MB/s) due to a hardware protocol that provides automatic address and strobe generation. EPP revisions 1.7 and 1.9 are both supported. For the parallel interface to be initialized for EPP mode, a negotiation phase is entered to detect whether or not the connected peripheral is compatible with EPP mode.

If compatible, then EPP mode can be used. In EPP mode, system timing is closely coupled to

EPP timing. A watchdog timer is used to prevent system lockup.

5.5.3 Extended Capabilities Port Mode

The Extended Capabilities Port (ECP) mode, like EPP, also uses a hardware protocol-based design that supports transfers up to 2 MB/s. Automatic generation of addresses and strobes as well as Run Length Encoding (RLE) decompression is supported by ECP mode. The ECP mode includes a bi-directional FIFO buffer that can be accessed by the CPU using DMA or programmed I/O. For the parallel interface to be initialized for ECP mode, a negotiation phase is entered to detect whether or not the connected peripheral is compatible with ECP mode. If compatible, then ECP mode can be used.

The ECP mode includes several sub-modes as determined by the Extended Control register. Two submodes of ECP allow the parallel port to be controlled by software. In these modes, the FIFO is cleared and not used, and DMA and RLE are inhibited.

Input/Output Interfaces

5.6 Keyboard/Pointing Device Interface

The keyboard/pointing device interface function is provided by the SIO controller component, which integrates 8042-compatible keyboard controller logic (hereafter referred to as simply the

“8042”) to communicate with the keyboard and pointing device using bi-directional serial data transfers. The 8042 handles scan code translation and password lock protection for the keyboard as well as communications with the pointing device.

5.6.1 Keyboard Interface Operation

The data/clock link between the 8042 and the keyboard is uni-directional for Keyboard Mode 1 and bi-directional for Keyboard Modes 2 and 3. (These modes are discussed in detail in

Appendix C). This section describes Mode 2 (the default) mode of operation.

Communication between the keyboard and the 8042 consists of commands (originated by either the keyboard or the 8042) and scan codes from the keyboard. A command can request an action or indicate status. The keyboard interface uses IRQ1 to get the attention of the CPU.

The 8042 can send a command to the keyboard at any time. When the 8042 wants to send a command, the 8042 clamps the clock signal from the keyboard for a minimum of 60 us. If the keyboard is transmitting data at that time, the transmission is allowed to finish. When the 8042 is ready to transmit to the keyboard, the 8042 pulls the data line low, causing the keyboard to respond by pulling the clock line low as well, allowing the start bit to be clocked out of the 8042.

The data is then transferred serially, LSb first, to the keyboard (Figure 5-6). An odd parity bit is sent following the eighth data bit. After the parity bit is received, the keyboard pulls the data line low and clocks this condition to the 8042. When the keyboard receives the stop bit, the clock line is pulled low to inhibit the keyboard and allow it to process the data.

Control of the data and clock signals is shared by the 8042 and the keyboard depending on the originator of the transferred data. Note that the clock signal is always generated by the keyboard.

After the keyboard receives a command from the 8042, the keyboard returns an ACK code. If a parity error or timeout occurs, a Resend command is sent to the 8042.

5.6.2 Pointing Device Interface Operation

The pointing device (typically a mouse) connects to a 6-pin DIN-type connector that is identical to the keyboard connector both physically and electrically. The operation of the interface (clock and data signal control) is the same as for the keyboard. The pointing device interface uses the

IRQ12 interrupt.

5.6.3 Keyboard/Pointing Device Interface Connector

The legacy-light model provides separate PS/2 connectors for the keyboard and pointing device.

Both connectors are identical both physically and electrically. Figure 5-7 and Table 5-6 show the connector and pinout of the keyboard/pointing device interface connectors.

5.7 Universal Serial Bus Interface

The Universal Serial Bus (USB) interface provides asynchronous/isochronous data transfers with compatible peripherals such as keyboards, printers, or modems. This high-speed interface supports hot-plugging of compatible devices, making possible system configuration changes without powering down or even rebooting systems.

These systems provide eight externally-accessible USB ports, two front panel USB ports (which may be disabled) and six USB ports on the rear panel. In addition, the SFF and CMT form factors support a media reader accessory that uses two USB ports through a system board connection.

The USB ports are dynamically configured to either a USB 1.1 controller or the USB 2.0 controller depending on the capability of the peripheral device. The 1.1 controllers provide a maximum transfer rate of 12 Mb/s while the 2.0 controller provides a maximum transfer rate of

480 Mb/s. Table 5-7 shows the mapping of the USB ports.

Input/Output Interfaces

These systems use the HD audio controller of the 82801 component to access and control an

Analog Devices AD1884A HD Audio Codec, which provides 2-channel high definition analog-to-digital (ADC) and digital-to-analog (DAC) conversions. A block diagram of the audio subsystem is shown in Figure 5-9. All control functions such as volume, audio source selection, and sampling rate are controlled through software through the HD Audio Interface of the 82801

ICH component. Control data and digital audio streams (record and playback) are transferred between the ICH and the Audio Codec over the HD Audio Interface. The codec’s speaker output is applied to a 1.5-watt amplifier that drives the internal speaker. A device plugged into the

Headphone jack or the line input jack is sensed by the system, which will inhibit the Speaker

Audio signal.

These systems provide the following analog interfaces for external audio devices:

Microphone In—This input uses a three-conductor 1/8-inch mini-jack that accepts a stereo microphone.

Line In—This input uses a three-conductor (stereo) 1/8-inch mini-jack designed for connection of a high-impedance audio source such as a tape deck. This jack can be re-tasked to a

Microphone In function.

Headphones Out—This input uses a three-conductor (stereo) 1/8-inch mini-jack that is designed for connecting a set of 32-ohm (nom.) stereo headphones. Plugging into the

Headphones jack mutes the signal to the internal speaker and the Line Out jack as well.

Line Out—This output uses a three-conductor (stereo) 1/8-inch mini-jack for connecting left and right channel line-level signals. Typical connections include a tape recorder's Line In

(Record In) jacks, an amplifier's Line In jacks, or to powered speakers that contain amplifiers.

5.8.2 HD Audio Link Bus

The HD audio controller and the HD audio codec communicate over a five-signal HD Audio

Link Bus (Figure 5-10). The HD Audio Interface includes two serial data lines; serial data out

(SDO, from the controller) and serial data in (SDI, from the audio codec) that transfer control and PCM audio data serially to and from the audio codec using a time-division multiplexed

(TDM) protocol. The data lines are qualified by the 24-MHz BCLK signal driven by the audio controller. Data is transferred in frames synchronized by the 48-KHz SYNC signal, which is derived from the clock signal and driven by the audio controller. When asserted (typically during a power cycle), the RESET- signal (not shown) will reset all audio registers to their default values.

The Network Interface Controller includes the following features:

VLAN tagging with Windows XP and Linux

Multiple VLAN support with Windows XP

Power management support for ACPI 1.1, PXE 2.0, WOL, ASF 1.0, and IPMI

Cisco Etherchannel support

Link and Activity LED indicator drivers

The controller features high and low priority queues and provides priority-packet processing for networks that can support that feature. The controller's micro-machine processes transmit and receive frames independently and concurrently. Receive runt (under-sized) frames are not passed on as faulty data but discarded by the controller, which also directly handles such errors as collision detection or data under-run.

The NIC uses 3.3 VDC auxiliary power, which allows the controller to support Wake-On-LAN

(WOL) and Alert-On-LAN (AOL) functions while the main system is powered down.

For the features in the following paragraphs to function as described, the system unit must be plugged into a live AC outlet. Controlling unit power through a switchable power strip will, with the strip turned off, disable any wake, alert, or power mangement functionality.

Technical Reference Guide

Input/Output Interfaces

5.9.1 Wake-On-LAN Support

The NIC supports the Wired-for-Management (WfM) standard of Wake-On-LAN (WOL) that allows the system to be booted up from a powered-down or low-power condition upon the detection of special packets received over a network. The NIC receives 3.3 VDC auxiliary power while the system unit is powered down in order to process special packets. The detection of a

Magic Packet by the NIC results in the PME- signal on the PCI bus to be asserted, initiating system wake-up from an ACPI S1 or S3 state.

5.9.2 Alert Standard Format Support

Alert Standard Format (ASF) support allows the NIC to communicate the occurrence of certain events over a network to an ASF 1.0-compliant management console and, if necessary, take action that may be required. The ASF communications can involve the following:

Alert messages sent by the client to the management console.

Maintenance requests sent by the management console to the client.

Description of client's ASF capabilities and characteristics.

The activation of ASF functionality requires minimal intervention of the user, typically requiring only booting a client system that is connected to a network with an ASF-compliant management console.

5.9.3 Power Management Support

The NIC features Wired-for-Management (WfM) support providing system wake up from network events (WOL) as well as generating system status messages (AOL) and supports ACPI power management environments. The controller receives 3.3 VDC (auxiliary) power as long as the system is plugged into a live AC receptacle, allowing support of wake-up events occurring over a network while the system is powered down or in a low-power state.

The Advanced Configuration and Power Interface (ACPI) functionality of system wake up is implemented through an ACPI-compliant OS and is the default power management mode. The following wakeup events may be individually enabled/disabled through the supplied software driver:

■ Magic Packet—Packet with node address repeated 16 times in data portion

The following functions are supported in NDIS5 drivers but implemented through remote management software applications (such as LanDesk).

Individual address match—Packet with matching user-defined byte mask

Multicast address match—Packet with matching user-defined sample frame

ARP (address resolution protocol) packet

Flexible packet filtering—Packets that match defined CRC signature

The PROSet Application software (pre-installed and accessed through the System Tray or

Windows Control Panel) allows configuration of operational parameters such as WOL and duplex mode.

Integrated Graphics Subsystem

6.1 Introduction

This chapter describes the graphics subsystem that is integrated into the Q45 GMCH component.

This graphics subsystem employs the use of system memory to provide efficient, economical 2D and 3D performance.

All systems provide dual-monitor support in the standard configuration. The SFF and CMT systems include two PCIe graphics slots for upgrading the graphics controller by:

■ Installing a PCIe x16 graphics card in the PCIe x16 graphics slot, which disables the integrated graphics controller

■ Installing a PCIe x4 graphics card in the PCIe x4 slot (x16 connector), in which the integrated graphics controller can be re-enabled through the BIOS settings

6.2 Functional Description

The Intel Q45 GMCH component includes an Intel integrated Graphics Media Accelerator

(GMA) 4500 controller (Figure 6-1). The GMA 4500 operates off the internal PCIe x16 bus and can directly drive an external, analog multi-scan monitor and a DisplayPort-compatible digital monitor simultaneously. The GMA 4500 includes a memory management feature that allocates portions of system memory for use as the frame buffer and for storing textures and 3D effects.

The GMA 4500 provides the following features:

■ Rapid pixel and texel rendering using four pipelines that allow 2D and 3D operations to overlap, speeding up visual effects, reducing the amount of memory for texture storage

■ Zone rendering for optimizing 3D drawing, eliminating the need for local graphics memory by reducing the bandwidth

■ Dynamic video memory allocation, where the amount of memory required by the application is acquired (or released) by the controller

■ Intelligent memory management allowing tiled memory addressing, deep display buffering, and dynamic data management

Integrated Graphics Subsystem

The GMA 4500 uses a portion of system memory for instructions, textures, and frame (display) buffering. Using a process called Dynamic Video Memory Technology (DVMT), the controller dynamically allocates display and texture memory amounts according to the needs of the application running on the system.

The total memory allocation is determined by the amount of system memory installed in a system. The video BIOS pre-allocates 8 megabytes of memory during POST. System memory that is pre-allocated is not seen by the operating system, which will report the total amount of memory installed less the amount of pre-allocated memory.

The GMA 4500 will use, in standard VGA/SVGA modes, pre-allocated memory as a true dedicated frame buffer. If the system boots with the OS loading the GMA Extreme Graphics drivers, the pre-allocated memory will then be re-claimed by the drivers and may or may not be used by the GMA in the “extended” graphic modes. However, it is important to note that pre-allocated memory is available only to the GMA, not to the OS.

The Q45's DVMT function is an enhancement over the Unified Memory Architecture (UMA) of earlier systems. The DVMT of the Q45 selects, during the boot process, the maximum graphics memory allocation possible according on the amount of system memory installed:

Table 6-1.

GMA 4500 Memory Allocation

SDRAM Installed Maximum Memory Allocation

1 GB

> 1 GB

256 or 512 MB

384 MB

The actual amount of system memory used by the GMA in the “extended” or “extreme” modes will increase and decrease dynamically according to the needs of the application. The amount of memory used solely for graphics (video) may be reported in a message on the screen, depending on the operating system and/or applications running on the machine.

For viewing the maximum amount of available frame buffer memory MS Windows go to the

Control Panel and select the Display icon, then > Settings > Advanced > Adapter.

The Microsoft Direct Diagnostic tool included in most versions of Windows may be used to check the amount of video memory being used. The Display tab of the utility the “Approx. Total

Memory” label will indicate the amount of video memory. The value will vary according to OS.

Some applications, particularly games that require advanced 3D hardware acceleration, may not install or run correctly on systems using the GMA.

All systems include both a legacy VGA connector and a DisplayPort interface. The DisplayPort is an alternate solution to (but not compatible with) HDMI and DVI. The DisplayPort interface consists of four data pair links, each of which can carry video, audio, and clock signals at a transfer rate of 1.62 or 2.7 Gb/s.

The DisplayPort interface provides multimode support through the use of an optional external adapter for connecting a DVI or VGA monitor.

6.4 Upgrading

All systems provide direct, dual-monitor support; a VGA montor and a DisplayPort monitor can be connected and driven simultaneously. The SFF and CMT systems also include a PCIe x16 graphics connector that specifically supports a PCIe x16 graphics card and a PCIe x16 connector that provides PCIe x4 operation for an x4 or x16 PCIe card. These two PCIe slots provide the

SFF and CMT form factors with flexible graphics upgrade paths.

The upgrade procedure for SFF and CMT formfactors is as follows:

1. Shut down the system through the operating system.

2. Unplug the power cord from the rear of the system unit.

3. Remove the chassis cover.

4. Install the graphics card into the PCIe x16 graphics slot or the PCIe x4/x16 slot.

5. Replace the chassis cover.

6. Reconnect the power cord to the system unit.

7. Power up the system unit:

If a PCIe graphics controller card is installed in the PCIe x16 graphics slot, the BIOS will detect the presence of the PCIe card and disable the integrated GMA of the Q45 GMCH. In this configuration, the integrated GMA cannot be enabled.

If a PCIe graphics controller card is installed in the PCIe x4 /x16 slot, the integrated GMA will be disabled by default, but can be re-enabled through the BIOS settings to allow an alternate method of multi-monitor operation. Press the

F10 key during the boot process to enter the

ROM-based Setup utility and re-enable the GMA for multi-monitor operation. A PCIe x16 card installed in the PCIe x4/x16 slot will be limited to x4 operation.

Two PCIe graphics can be installed in an SFF or CMT simultaneously to provide an alternate method for multi-monitor support. In this configuration, the integrated GMA will be disabled.

Power and Signal Distribution

7.1 Introduction

This chapter describes the power supplies and discusses the methods of general power and signal distribution. Topics covered in this chapter include:

Power distribution (7.2)

Power Control (7.3)

Signal distribution (7.4)

Each form factor uses a unique power supply assembly and implements different methods of power generation and distribution. The USDT form factor uses an external (“brick”) supply while the SFF and CMT form factors use a power supply unit contained within the system chassis. The subassemblies are not interchangeable between the three form factors.

7.2.1 USDT Power Distribution

The USDT form factor uses an external (“brick”) supply that connects to the chassis through a three-conductor cable (Figure 7-1). All voltages required by the processing circuits, peripherals, and storage devices are produced on the system board from the 19.5 VDC produced by the external power supply assembly. The external power supply always produces 19.5 VDC as long as it is connected to an active AC outlet.

Power and Signal Distribution

The generation of +3, +5, and +12 VDC is controlled digitally with the PS On signal. When the

PS On signal is asserted, all DC voltages are produced. When PS On is de-asserted, only auxiliary power (+5 AUX) is generated. The +5 AUX voltage is always produced as long as the system is connected to a live AC source.

7.3.1 Power Button

The PS On signal is typically controlled through the Power Button which, when pressed and released, applies a negative (grounding) pulse to the power control logic on the system board.

The resultant action of pressing the power button depends on the state and mode of the system at that time and is described as follows:

System State

Off

On, ACPI Disabled

On, ACPI Enabled

Table 7-4.

Power Button Actions

Pressed Power Button Results In:

Negative pulse, of which the falling edge results in power control logic asserting PS On signal to Power Supply Assembly, which then initializes. ACPI four-second counter is not active.

Negative pulse, of which the falling edge causes power control logic to de-assert the PS On signal. ACPI four-second counter is not active.

Pressed and Released Under Four Seconds:

Negative pulse, of which the falling edge causes power control logic to generate SMI-, set a bit in the SMI source register, set a bit for button status, and start four-second counter. Software should clear the button status bit within four seconds and the Suspend state is entered. If the status bit is not cleared by software in four seconds PS On is de-asserted and the power supply assembly shuts down (this operation is meant as a guard if the OS is hung).

Pressed and Held At least Four Seconds Before Release:

If the button is held in for at least four seconds and then released, PS On is negated, de-activating the power supply.

Power and Signal Distribution

7.3.2 Wake Up Events

The PS On signal can be activated with a power “wake-up” of the system due to the occurrence of a magic packet, serial port ring, or PCI power management event (PME). These events can be individually enabled through the Setup utility to wake up the system from a sleep (low power) state.

Wake-up functionality requires that certain circuits receive auxiliary power while the system is turned off. The system unit must be plugged into a live AC outlet for wake up events to function.

Using an AC power strip to control system unit power will disable wake-up event functionality.

The wake up sequence for each event occurs as follows:

Wake-On-LAN

The network interface controller (NIC) can be configured for detection of a “Magic Packet” and wake the system up from sleep mode through the assertion of the PME- signal on the PCI bus.

Refer to Chapter 5, “Network Support” for more information.

Modem Ring

A ring condition on a serial port can be detected by the power control logic and, if so configured, cause the PS On signal to be asserted.

Power Management Event

A power management event that asserts the PME- signal on the PCI bus can be enabled to cause the power control logic to generate the PS On. Note that the PCI card must be PCI ver. 2.2 (or later) compliant to support this function.

SYSTEM BIOS

8.1 Introduction

The System Basic Input/Output System (BIOS) of the computer is a collection of machine language programs stored as firmware in read-only memory (ROM). The system BIOS includes such functions as Power-On Self Test (POST), PCI device initialization, Plug 'n Play support, power management activities, and the Setup utility. The firmware contained in the system BIOS

ROM supports the following operating systems and specifications:

DOS 6.2, Windows 2000, XP, and Vista (Home and Professional versions)

Windows NT 4.0 (SP6 required for PnP support)

OS/2 ver 2.1 and OS/2 Warp

SCO Unix

DMI 2.1

Intel Wired for Management (WfM) ver. 2.2

Alert Standard Format (ASF) 2.0

ACPI and OnNow

SMBIOS 2.5

Intel PXE boot ROM for the integrated LAN controller

BIOS Boot Specification 1.01

Enhanced Disk Drive Specification 3.0

“El Torito” Bootable CD-ROM Format Specification 1.0

ATAPI Removeable Media Device BIOS Specification 1.0

Serial ATA Advanced Host Controller Interface (AHCI) 1.2

ATA with Packet Interface (ATA/ATAPI-7

The BIOS firmware is contained in a 32 Mb flash ROM part. The runtime portion of the BIOS resides in a 128KB block from E0000h to FFFFFh.

This chapter includes the following topics:

ROM flashing (8.2)

Boot functions (8.3)

Client management functions (8.4)

SMBIOS support (8.5)

USB legacy support (8.6)

Management engine functions (8.7)

Technical Reference Guide www.hp.com

8-1

SYSTEM BIOS

8.2 ROM Flashing

The system BIOS firmware is contained in a flash ROM device that can be re-written with new

BIOS code using a flash utility locally (with F10 setup), with the HPQFlash program in a

Windows environment, or with the FLASHBIN.EXE utility in a DOS or DOS-like environment.

8.2.1 Upgrading

Upgrading the BIOS is not normally required but may be necessary if changes are made to the unit's operating system, hard drive, or processor. All System BIOS upgrades are available directly from HP. Flashing is done either locally through F10 setup, the HPQFlash program in a

Windows environment, or with the FLASHBIN.EXE utility in a DOS or DOS-like environment.

Flashing may also be done by deploying either HPQFlash or FLASHBIN.EXE through the network boot function.

This system includes 64 KB of write-protected boot block ROM that provides a way to recover from a failed flashing of the system BIOS ROM. If the system BIOS ROM fails the flash check, the boot block code provides the minimum amount of support necessary to allow booting the system and re-flashing the system BIOS ROM with a CD or USB disk/thumb drive.

8.2.2 Changeable Splash Screen

A corrupted splash screen may be restored by reflashing the BIOS image through F10 setup, running HPQFlash, or running FLASHBIN.EXE. Depending on the system, changing

(customizing) the splash screen may only be available with asistance from HP.

The splash screen (image displayed during POST) is stored in the system BIOS ROM and may be replaced with another image of choice by using the Image Flash utility (Flashi.exe). The

Image Flash utility allows the user to browse directories for image searching and pre-viewing.

Background and foreground colors can be chosen from the selected image's palette.

The splash screen image requirements are as follows:

Format = Windows bitmap with 4-bit RLE encoding

Size = 424 (width) x 320 (height) pixels

Colors = 16 (4 bits per pixel)

File Size = < 64 KB

The Image Flash utility can be invoked at a command line for quickly flashing a known image as follows:

>\Flashi.exe [Image_Filename] [Background_Color] [Foreground_Color]

The utility checks to insure that the specified image meets the splash screen requirements listed above or it will not be loaded into the ROM.

SYSTEM BIOS

8.3 Boot Functions

The BIOS supports various functions related to the boot process, including those that occur during the Power On Self-Test (POST) routine.

8.3.1 Boot Device Order

The default boot device order is as follows:

1. CD-ROM drive (EL Torito CD images)

2. Diskette drive (A:)

3. USB device

4. Hard drive (C:)

5. Network interface controller (NIC)

The above order assumes all devices are present in the initial configuration. If, for example, a diskette drive is not initially installed but added later, then drive A would be added to the end of the order (after the NIC)

The order can be changed in the ROM-based Setup utility (accessed by pressing F10 when so prompted during POST). The options are displayed only if the device is attached, except for USB devices. The USB option is displayed even if no USB storage devices are present. The hot IPL option is available through the F9 utility, which allows the user to select a hot IPL boot device.

8.3.2 Network Boot (F12) Support

The BIOS supports booting the system to a network server. The function is accessed by pressing the F12 key when prompted at the lower right hand corner of the display during POST. Booting to a network server allows for such functions as:

Flashing a ROM on a system without a functional operating system (OS).

Installing an OS.

Installing an application.

These systems include, as standard, an integrated Intel 82562-equivalent NIC with Preboot

Execution Environment (PXE) ROM and can boot with a NetPC-compliant server.

8.3.3 Memory Detection and Configuration

This system uses the Serial Presence Detect (SPD) method of determining the installed DIMM configuration. The BIOS communicates with an EEPROM on each DIMM through the SMBus to obtain data on the following DIMM parameters:

Presence

Size

Type

Timing/CAS latency

Refer to Chapter 3, “Processor/Memory Subsystem” for the SPD format and DIMM data specific to this system.

Technical Reference Guide www.hp.com

8-3

SYSTEM BIOS

The BIOS performs memory detection and configuration with the following steps:

1. Program the buffer strength control registers based on SPD data and the DIMM slots that are populated.

2. Determine the common CAS latency that can be supported by the DIMMs.

3. Determine the memory size for each DIMM and program the GMCH accordingly.

4. Enable refresh.

8.3.4 Boot Error Codes

The BIOS provides visual and audible indications of a failed system boot by using the system’s power LED and the system board speaker. The error conditions are listed in the following table.

Visual (power LED)

Blinks red 2 times @ 1 Hz

Blinks red 3 times @ 1 Hz

Bli nks red 4 times @ 1 Hz

SYSTEM BIOS

8.6 USB Legacy Support

The system BIOS ROM checks the USB port, during POST, for the presence of a USB keyboard.

This allows a system with only a USB keyboard to be used during ROM-based setup and also on a system with an OS that does not include a USB driver.

On such a system a keystroke will generate an SMI and the SMI handler will retrieve the data from the device and convert it to PS/2 data. The data will be passed to the keyboard controller and processed as in the PS/2 interface. Changing the delay and/or typematic rate of a USB keyboard though BIOS function INT 16 is not supported.

8.7 Management Engine Functions

The management engine function of Intel AMT allows a system unit to be managed remotely over a network, where or not the system is powered up or not 1 . The system BIOS can request the management engine to generate the following alerts:

Temperature alert

Fan failure alert

Chassis intrusion alert

Watchdog timer alert

No memory installed alert
