This section provides an overview for the MicroATX Pentium
II based
PCI/ISA Printed Wiring Assembly (PWA) code-named "IN440EX-D-D". It describes functional blocks and their relationship. The following diagram shows the functional blocks
1.1. Overview
The IN440EX-D-D is an implementation of BCM Advanced Research for a
High-Volume MicroATX motherboard featuring these subsystems:
§ Intel Pentium™ II MMX Processor cartridge support through the SLOT 1 connector
§ Intel 82440EX PCIset: 82443EX (“PAC” PCI A.G.P. Controller) and

§
Accelerated Graphics Port “AGP” connector
§
PCI IDE Bus Master interface
§
Embedded advanced I/O support
§ System Management Logic
§ Advanced multiple Audio interface
§
USB (Universal Serial Bus)
§
System Monitoring Hardware
§
MicroATX form-factor motherboard
The targeted Operating Systems for the IN440EX-D-D are: Windows 95,
Windows 98 and Windows NT.
1.1.1. Processor Subsystem
The IN440EX-D has provisions to support the following processors: Intel
Pentium™ II Processor with MMX™ technology (Deschutes) operating at
333/66, 300/66, 266/66 and 233/66, Celeron at 366/66, 400/66 and 433/66
MHz. The Processor speeds are selectable with a four, (4) jumper block combination for the bus-to-core frequency ratio and CPU bus speed. The bus-to-core ratio is either 2/7, 1/4, 2/9 or 1/5 yielding the bus/core frequency;
66/233, 66/266, 66/300, 66/333, 66/366, 66/400 or 66/433 MHz respectively.
High-performance features, including pipelined 32-bit addressing, 64-bit data, 16KB/16KB Instruction/Data Write-back or Write-through 2-way set
15
INTRODUCTION associative primary cache. 0KB/512KB Write-back direct mapped secondary cache on the CPU Cartridge using a Back-Side-Bus (BSB). Two (2) Memory
DIMM for support of SDRAM.
Two onboard DC/DC converters supply the +2.5 Volts for the CPU I/O voltage and the +1.5 Volts GTL+ bus voltage (VTT). An on-board switching power converter supplies the CPU core voltage (VCORE), the switcher supports the Pentium
II Voltage-ID pins for auto-voltage programming of the switcher supply.
1.1.2. Cache Subsystem
The cache and control functions are part of the Pentium
II Processor. The cache SRAM interface is through the processor’s Back-Side-Bus (BSB) and is included within the CPU cartridge.
The IN440EX-D can accept either the Pentium
II cartridge with 512KB of second level (L2) Pipelined Burst SRAM cache. The Pentium
II second level cache supports a direct mapped organization with a write-back policy, providing all necessary snoop functions and inquire cycles. Cacheability of the entire memory space in the first level cache is supported. For the second level cache only the first 512MB of main memory is cacheable, and only main memory controlled by the PAC DRAM interface will be cached, PCI and
ISA memory is not cached.
1.1.3. Memory Subsystem
The IN440EX-D DRAM controller supports a 64-bit memory data interface, optionally supporting 64-bit wide DIMM modules, without ECC/EC. The
DRAM types supported are Synchronous DRAM (SDRAM). SDRAM is supported at 66 MHz using symmetrical addressing.
The IN440EX-D Main Memory interface provides two (2) 168-pin DIMM socket (DIMM0 and DIMM1) sites, allowing system memory from 8MB to
256MB of SDRAM.
The DIMM sockets support either single or double-sided ‘Unbuffered DIMM’ modules. The installed DRAM type can be 8MB, 16MB, 32MB, 64MB or
128MB DIMMs. The DRAM Controller uses the JEDEC standard Serial
Presence Detect (SPD) Mechanism to detect memory and array configurations, there is no jumper settings required for the memory size.
Memory is automatically detected by the system BIOS.
Rules for Populating the DIMM memory array
16
INTRODUCTION
§ DIMM sockets can be populated in any order.
§ The DRAM Timing register, which provides the DRAM speed grade control for the entire memory array, will be programmed to use the timings of the slowest DRAMs installed.
1.1.4. Data Integrity Subsystem
Several data integrity features are included in the system. These are 64-bit
DRAM interface for EX chipset, parity generation and checking on the PCI
Bus and A.G.P. (for PCI transactions).
PCI Bus.
The system implements parity generation/checking as defined by the PCI specification.
A.G.P. Bus.
For the operations on the A.G.P. interface using PCI protocol, the system supports Parity generation/checking as defined by the PCI specification.
Main Memory DRAM Protection Modes.
The system supports three modes of data protection of the DRAM array:
Non-ECC with Byte-Wise Write Support (Default mode, in this mode there is no provision for protecting the integrity of data in the DRAM array.)
1.1.5. A.G.P. Interface
The A.G.P. is a high performance, component level interconnect targeted at
3D graphics applications and is based on a set of performance enhancements to PCI. The IN440EX-D is designed to support the A.G.P.
Interface.
The A.G.P. implementation is compatible with the Accelerated Graphics Port
Specification. The system supports only a synchronous A.G.P. interface coupling to the host bus frequency. The actual bandwidth will be limited by the capability of the system’s memory, reaching the highest performance with fast SDRAM. The A.G.P. Interface supports PCI operations as defined by the PCI specification. Electrically, only 66MHz PCI operations are supported.
For the definition of A.G.P. Interface functionality (protocols, rules and signalling mechanisms, as well as the platform aspect of A.G.P. functionality), refer to the latest A.G.P. Interface Specification. This
17
INTRODUCTION document focuses only on the Controller specifics of the A.G.P. interface functionality.
1.1.6. Embedded PCI Devices
The PCI bus contains 1 embedded PCI device: PCI bus mastering IDE interface. The arbiter within the PAC performs arbitration for PCI bus masters.
1.1.7. PCI Bus Master IDE
PIIX-4 provides an integrated Bus Mastering IDE controller with two high performance IDE interfaces for up to four devices, such as Hard Drives and
CD-ROM.
1.1.8. PCI Add-in Cards
High Performance PCI I/O cards can be used in the IN440EX-D through the
PCI connector slots. The PCI bus is specified to support 10 loads. Each embedded controller or bridge (Video, PCI to ISA Bridge) count as 1 load, each PCI expansion slot used counts as 2 loads. To support multiple PCI devices in a single slot, add an expansion board containing PCI to PCI
Bridge to a secondary PCI segment.
1.1.9. Embedded A.G.P. Devices
The AGP bus contains 1 embedded device: The ATI 3D Rage Pro Turbo 2X
Graphics Accelerator. The 3D Rage Pro is a highly integrated graphics controller, integrating the 2D, 3D and video accelerators, palette DAC and quadruple clock synthesiser.
1.1.10. Embedded I/O Subsystem
The Winbond Plug and Play Ultra I/O controller “W83977TF” represents the newest technology in functionality and integration. While providing the standard PC I/O requirements the Ultra I/O complies with the ISA Plug-and-
Play standard version 1.0a, and provides for the recommended functionality to support Windows 95. The Ultra I/O qualifies 16-bit address to allow relocation of 480 different addresses, with 13 IRQ options and 3 DMA channels available for each logical device.
18
INTRODUCTION
Other features of the Ultra I/O are: 8042 keyboard controller. An Infrared interface for Fast IR (FIR), IrDA and ASKIR. Floppy interface. Two serial ports with 16-byte FIFOs. One EPP/ECP supported bi-directional parallel port.
1.1.11. System Management Subsystem
The IN440EX-D support the System Monitor services using Winbond’s
W83781D System Management chip. The W83781D is used to monitor
Voltage, Temperature and Fan Speed. The combination of the System
Monitor and the Wake On LAN (WOL) functionality achieves the
Management Level 3.
1.1.12. Advanced Configuration and Power Interface “ACPI”
The IN440EX-D supports the ACPI specification and its key elements; The
Operating System Directed Power Management (OSPM). ACPI evolves the existing collection of power management BIOS code, APM APIs, PNP BIOS
APIs, and so on into a well-specified power management and configuration mechanism. It provides support for an orderly transition from existing
(legacy) hardware to ACPI hardware, and it allows for both mechanisms to exist in a single machine and be used as needed. ACPI evolves the existing motherboard configuration interfaces to support these advanced architectures in a more robust, and potentially more efficient manner.
OSPM provides a new appliance interface to customers. In particular, it provides for a sleep button. This sleep button is a “soft” button, which does not turn the machine physically off but signals the OS to go into a ‘soft off’ or sleeping state. ACPI defines two types of these “soft” buttons: one for putting the machine into sleep mode and one for putting the machine into ‘soft off’ mode.
This gives the OEM two different ways to implement machines: A one or a two-button model. The button on the one-button model can be used as a power button or a sleep button as determined by user settings. The twobutton model has an easily accessible sleep button and a separate power button. In either model, an override feature that forces the machine to turn off or to reset without OS consent is also needed to deal with various rare, but problematic, situations.

FUNCTIONAL ARCHITECTURE
2.5. Video Subsystem
3D RAGE PRO Graphics Controller is a highly integrated graphics controller.
Incorporated within this single chip are the 2D, 3D and video accelerators, palette DAC, and quadruple clock synthesiser. This multi-function integrated controller delivers superior 3D performance, TV-quality scaled video optimized for MPEG playback, industry-leading Mach64 2D performance, and video expansion capability suited for video conferencing, cable TV viewing, and hardware MPEG decoding.
The availability of ATI BIOS, drivers, utilities, and application software developed for the entire chip family is a major strength for the 3D RAGE
PRO. Being register-compatible with all other controllers in the Mach64 accelerator series means immediate compatibility with a wide range of application drivers. Since this controller is also pin-compatible with ATI's family of other mach64 integrated controllers, it provides to the OEM a lowcost upgrade path to additional features and performance.
This controller uses active power management techniques to monitor activity levels within its’ self and to perform real-time power reductions such as dynamic clock control and graphics engine shutdown. Because full-speed operation can be restored without delay, these techniques do not impact performance. Major advances have been included in this chip to boost performance in the area of a new bus interface, Accelerated Graphics Port
(AGP). With AGP data the throughput between host and 3D RAGE PRO has greatly increased. The result is even faster 2D and 3D performance and enhancements to motion video support (e.g. MPEG-2 motion compensation).

2.9.6. Real-Time Clock
The integrated Real Time Clock (RTC) is DS12887/MC146818 compatible and provides the time of day clock, 100-year calendar with alarm features and is accurate to within 1 minute per month, it consumes less than 1
µ
A of standby current (Typ.). The (RTC) supports 256 bytes of battery backed
Non-volatile CMOS memory in two banks of 128 bytes each, both banks being reserved for BIOS use. One bank of CMOS memory is used to maintain the clock and user-system-setting configuration parameters when the main system power is removed. The other bank (128 bytes) is lockable in 4x32 byte blocks and can be used to store and lock miscellaneous information.
The CMOS RAM can be set to specific values or cleared to the system default values using the BIOS SETUP program. Also to prevent a lock-up situation the CMOS RAM values can be cleared to the system defaults by using the CLR CMOS jumper on the PWA.
2.9.7. Non-volatile CMOS Memory Battery
An external coin-cell style battery provides power to the RTC and CMOS memory when system power is removed. The battery has an estimated lifetime of five to seven years and is socketed for easy replacement.

The input power is supplied via the ATX power supply. The ATX power supply incorporates the power supply connector (J17) on the system PWA.
4.3.2. Input Power Budget
The +5V current available reflects the rating of the power connector. The
Power itself may deliver more so the system integrator must be sure that the total load does not exceed the system power supply or board power connector rating, whichever is less. The rating of the ISA slots is 4.5A per slot. The ISA specification recommends supporting an average of 3.0A per slot. The average current consumption may not exceed 3A per slot. The system integrator must also guarantee that worst-case power consumption does not exceed the maximum allowed by the motherboard power connector.

I
I O S S E T
U
P
The IN440EX-D motherboard uses AWARD BIOS, which is stored in a Flash
EEPROM and can be upgraded by a floppy disk-based program. The BIIOS has a built-in Setup Program that allows users to modify the basic system configuration settings. The settings are then stored in a dedicated batterybacked memory, called CMMOS RAM that retains the information when the power is turned off. The BIOS provides critical low-level support for the system’s central processing, memory and I/O subsystems. The AWARD
BIOS has been customized by adding important, nonstandard, features such as virus and password protection, power management, and detailed finetuning of the chipset which controls the system. The remainder of this manual is intended to guide you through the process of configuring your system using the BIOS Setup.
5.1. How To Enter BIOS Setup
The AWARD BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking the system and configuring it through the power-on self test (POST). When these preliminaries are finished, the BIOS seek an operation system on the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands over control of system operation to it.
To start Setup, press the <Del> key during boot-up before or while a message similar to this appears briefly at the bottom of the screen during
POST (Power On Self Test):
Press DEL if you want to enter SETUP
If the above message disappears before you have responded and you still wish to enter Setup, reboot the system to try again by pressing the “RESET” button on the system case. You may also restart by simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys.
Press F1 to continue, DEL to enter SETUP

5.1.2. Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to use and the possible selections for the highlighted item. To exit the Help
Window press Esc or the F1 key again.
5.1.3. In Case of Problems
If after making and saving system changes with Setup, you discover that your computer no longer is able to boot, the Award BIOS supports an override to the CMOS settings that resets your system to its default configuration.
The best advice is to alter only settings that you thoroughly understand. In particular, do not change settings in the Chipset screen without a good reason. BCM
Advanced Research Inc. or your system manufacturer for the best performance and reliability has carefully chosen the Chipset defaults. Even a seemingly small change to the Chipset setup may cause the system to become unstable.
5.2. Main Setup Menu
When you enter the Award BIOS CMOS Setup Utility, a Main Menu (Figure
1) appears on the screen. The Main Menu allows you to select from several
Setup functions and two exit choices. Use the arrow keys to select among the items and press Enter to accept and enter the sub-menu.

BIOS SETUP
The BIOS supports up to four IDE drives. This section does not show information about other IDE devices, such as a CD-ROM drive, or about other hard drive types, such as SCSI drives.
NOTE: We recommend that you select type AUTO for all drives.
The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type AUTO for a hard drive, the BIOS detects its specifications during POST, every time the system boots.
If you do not want to select drive type AUTO, other methods of selecting the drive type are available:
Match the specifications of your installed IDE hard drive(s) with the preprogrammed values for drive types 1 through 45.
Select USER and enter values into each drive parameter field.
Use the IDE HDD AUTO DECTECTION function in Setup.
Here is a brief explanation of drive specifications:
Type: The BIOS contains a table of pre-defined drive types. Each defined drive type has a specified number of cylinders, number of heads, write precompensation factor, landing zone, and number of sectors, Drives whose specifications do not accommodate any pre-defined type are classified as type USER.
Size: Disk drive capacity (approximate). Note that this size is usually slightly greater than the size of a formatted disk given by a disk-checking program.
Cyls: Number of cylinders
Head: Number of herds
Precomp: Write precompensation cylinder
Landz: Landing zone
Sector: Number of sectors
Mode: Auto, Normal, large, or LBA
Auto: The BIOS automatically determines the optimal mode.
Normal: Maximum number of cylinders, heads, and sectors supported are
1024, 16 and 63.
50
BIOS SETUP
Large: For drives that do not support LBA and have more than 1024 cylinders.
LBA (Logical Block Addressing): During drive accesses, the IDE controller
Transforms the data address described by sector, head, and cylinder number into a physical block address, significantly improving data transfer rates. For drives with greater than 1024 cylinders.
5.3.4. Drive A/B type
Select the correct specifications for the diskette drive(s) installed in the computer.
None No diskette drive installed
360K, 5.25 in 5-1/4 inch PC-type standard drive; 360 kilobyte capacity
1.2M, 5.25 in 5-1/4 inch AT-type high-density drive; 1.2 megabyte capacity
720K, 3.5 in 3-1/2 inch double-sided drive; 720 kilobyte capacity
1.44M, 3.5 in 3-1/2 inch double-sided drive; 1.44 megabyte capacity
2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity
5.3.5. Video
Select the type of primary video subsystem in your computer. The BIOS usually detects the correct video type automatically. The BIOS supports a secondary video subsystem, but you do not select it in Setup.
EGA/VG
A
Enhanced Graphics Adapter/Video Graphics Array. For EGA,
VGA, SEGA, SVGA or PGA monitor adapters.
CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode.
MONO Monochrome adapter includes high-resolution monochrome adapters.
5.3.6. Halt on
During the power-on self-test (POST), the computer stops if the BIOS detect a hardware error. You can tell the BIOS to ignore certain errors during
POST and continue the boot-up process. These are the selections:
No errors POST does not stop for any errors.
All errors If the BIOS detect any non-fatal error, POST stops and prompts you to take corrective action.
All, But POST does not stop for a keyboard error, but stops for all
51
BIOS SETUP
Keyboard other errors.
All, But Diskette POST does not stop for diskette drive errors, but stops for all other errors.
All, But
Disk/Key
POST does not stop for a keyboard or disk error, but stops for all other errors.
5.3.7. Memory
You cannot change any values in the Memory fields; they are only for your information. The fields show the total installed random access memory
(RAM) and amounts allocated to base memory, extended memory, and other
(high) memory, RAM is counted in kilobytes (KB: approximately one thousand bytes) and megabytes (MB: approximately one million bytes).
RAM is the computer’s working memory, where the computer stores programs and data currently being used, so they are accessible to the CPU.
Modern personal computers may contain up to 64MB, 128MB, or more.
Base Memory
Typically 640 KB. Also called conventional memory. The DOS operating system and conventional applications use this area.
Extended Memory
Above the 1-MB boundary. Early IBM personal computers could not use memory above 1 MB, but current PCs and their software can use extended memory.
Other Memory
Between 640 KB and 1 MB; often called High memory. DOS may load terminate-and- stay-resident (TSR) programs, such as device drivers, in this area, to free as much conventional memory as possible for applications. Lines in your
CONFIG.SYS file that start with LOADHIGH load programs into high memory
Total memory
System total memory is the sum of base memory, extended memory, and other memory.

5.4.1. Virus Warning
When enabled, you receive a warning message if a program (specifically, a virus) attempts to write to the boot sector or the partition table of the hard disk drive. You should then run an anti-virus program. Keep in mind that this feature protects only the boot sector, not the entire hard drive.
NOTE: Many disk diagnostic programs that access the boot sector table can trigger the virus-warning message. If you plan to run such a program, we recommend that you first disable the virus warning.
5.4.2. Quick Power On Self Test
Select Enabled allows system to shorten or skip certain checks during the
Power On Self Test(POST). The system will boot more quickly.
5.4.3. Boot Sequence
The original IBM PCs loaded the DOS operating system from drive A (floppy disk), so IBM PC-compatible systems are designed to search for an operating system first on drive A, and then on drive C (hard disk). However,
53
BIOS SETUP the BIOS now offers 10 different boot sequences options of three drive each.
In addition to the traditional drives A and C, options include IDE hard drives
D, E, and F; plus a SCSI hard drive and a CD-ROM drive.
5.4.4. Swap Floppy Drive
This field is effective only in systems with two floppy drives. Selecting
Enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B. or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KN<
1.2MB, and 1.44MB capacity all have 80 tracks. Because very few modern
PCs have 40-track
5.4.5. Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 floppy drives, we recommend that you set this field to Disabled to save time.
5.4.6. Boot Up NumLock Status
Toggle between On or off to control the state of the NumLock key when the system boots. When toggled on, the numeric keypad generates numbers instead of controlling cursor operations.
5.4.7. Typematic Rate Setting
When Disabled, the following two items (Typematic Rate and Typematic
Delay) are irrelevant. Keystrokes repeat at a rate determined by the keyboard controller in your system. When Enabled, you can select a typematic a\rate and typematic delay.
5.4.8. Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can select a typematic rate
(the rate at which character repeats when you hold down a key) of
6,8,10,12,15,20,24, or 30 characters per second.
5.4.9. Typematic Delay (Msec)
When the typematic rate setting is enabled, you can select a typematic delay
(the delay before keystrokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.
5.4.10. Security Option
If you have set a password, select whether the password is required every time the System boots, or only when you enter Setup.
54
BIOS SETUP
5.4.11. PCI/VGA Palette Snoop
Some display cards that are not standard VGA such as graphics accelerators or MPEG cards may not show the correct colors, the setting can correct this problem once you set it to Enable, To default setting leave at
Disabled.
5.4.12. Assign IRQ For VGA
Set this option to Yes to allocate an IRQ to VGA device on the PCI Bus. The setting are Enabled or Disabled.
5.4.13. OS select for DRAM>64MB
Select OS2 only if you are running OS/2 operating system with greater than
64MB of RAM on your system.
5.4.14. Shadow
Software that resides in a read-only memory (ROM) chip on a device is called firmware. The Award BIOS permits shadowing of firmware such as the system BIOS, video BIOS, and similar operating instructions that come with some expansion peripherals, such as, for example, a SCSI adapter.
Shadowing copy firmware from ROM into system RAM, where the CPU can read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must be read by the system through the 8-bit x-bus. Shadowing improves the performance of the system BIOS and similar ROM firmware for expansion peripherals, but it also reduces the amount of high memory (640KB to 1 MB) available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Many system designers hardwire shadowing of the system BIOS and eliminate a System
BIOS Shadow option.
Video BIOS shadows into memory area C0000-C7FFF> The remaining areas shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains
ROM-based firmware, you need to know the address range the ROM occupies to shadow it into the correct area of RAM.

5.5.1. SDRAM CAS latency Time
You can select CAS latency time in HCLKs of 2/2 or 3/3. The system board designer should set the values in this field, depending on the DRAM installed. Do not change the values in this field unless you change specifications of the installed DRAM or the installed CPU.
5.5.2. System BIOS Cacheable
Select Enabled allows caching of the system BIOS ROM at F000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.
5.5.3. Video BIOS Cacheable
56
BIOS SETUP
Select Enabled allows caching of the video BIOS ROM at F0000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.
5.5.4. Video RAM Cacheable
Select Enabled allows caching of the video RAM, resulting in better system performance. However, if any program writes to this memory area, a system error may result.
5.5.5. 8 Bit I/O Recovery Time
The recovery time is the length of time, measured in CPU clocks, which the system will delay after the completion of an input/output request. This delay takes place because the CPU is operating so much faster than the input/output bus that the CPU must be delayed to allow for the completion of the I/O.
This item allows you to determine the recovery time allowed for 8 bit I/O.
Choices are from NA, 1 to 8 CPU clocks.
5.5.6. 16 Bit I/O Recovery Time
This item allows you to determine the recovery time allowed for 16 bit I/O.
Choices are from NA, 1 to 4 CPU clocks.
5.5.7. Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved for ISA cards. This memory must be mapped into the memory space below
16 MB. You can reserve this area of system memory for ISA adapter ROM.
When that area is reserved it cannot be cached. The user information of peripherals that need to use this area of system memory usually discusses their memory requirements.
5.5.8. Passive Release
When Enabled, CPU to PCI bus accesses are allowed during passive release. Otherwise, the arbiter only accepts another PCI master access to local DRAM.
5.5.9. Delayed Transaction
The chipset has an embedded 32-bit posted write buffer to support delay transactions cycles. Select Enabled to support compliance with PCI specification version 2.1.
5.5.10. AGP Aperture Size (MB)
57
BIOS SETUP
Select the size of the Accelerated Graphics Port (AGP) aperture. The aperture is a portion of the PCI memory address range dedicated for graphics memory address space. Host cycles that hit the aperture range are forwarded to the AGP without any translation. See www.agpforum.org
for
AGP information.
5.5.11. Power-Up State

5.6.2. Power Management
58
BIOS SETUP
This option allows you to select the type (or degree) of power saving for
Doze, Standby, and Suspend modes. See the section PM Timers for a brief description of each mode. This table describes each power management mode:
Disable Global Power Management will be disabled
Max Saving Maximum power savings. Only Available for SL CPUs.
Inactivity period is 1 minute in each mode.
User Define Set each mode individually. Select time-out periods in the
PM Timers section, following.
Min Saving Minimum power savings. Inactivity period is 1 hour in each mode (except the hard drive).
5.6.3. PM Control by APM
If Advanced Power Management (APM) is installed on your system, selecting
Yes gives better power savings.
5.6.4. Video Off Method
Determines the manner in which the monitor is blanked.
V/H
SYNC+Blank
System turns off vertical and horizontal synchronization ports and writes blanks to the video buffer.
DPMS Support Select this option if your monitor supports the Display
Power Management Signaling (DPMS) standard of the
Video Electronics Standards Association (VESA). Use the software supplied for your video subsystem to select video power management values.
Blank Screen System only writes blanks to the video buffer.
5.6.5. Video Off After
As the system moves from lesser to greater power-saving modes, select the mode in which you want the monitor to blank.
5.6.6. MODEM Use IRQ
Name the interrupt request (IRQ) line assigned to the modem (if any) on your system. Activity of the selected IRQ always awakens the system.
5.6.7. Doze Mode
Defines the continuous idle time before the system entering DOZE mode.
The range is from 1 min to 1 Hr. If any item defined is enabled & active,
STANDBY timer will be reloaded
5.6.8. Standby Mode
59
BIOS SETUP
After the selected period of system inactivity (1 minute to 1 hour), the fixed disk drive and the video shut off while all other devices still operate at full speed.
5.6.9. Suspend Mode
After the selected period of system inactivity (1 minute to 1 hour), all devices except the CPU shut off.
5.6.10. HDD Power Down
After the selected period of drive inactivity (1 to 15 minutes), the hard disk drive powers down while all other devices remain active.
5.6.11. Throttle Duty Cycle
When the system enters Doze mode, the CPU clock runs only part of the time. You may select the percent of time that the clock runs.
5.6.12. VGA Active Monitor
When Enabled, any video activity restarts the global timer for Standby mode.
5.6.13. Soft-Off by PWR-BTTN
When this feature set to “Delay 4 sec.” , the system will become suspend once the Power Switch be pressed within 4 second, and the system will
Power Off once the Power Switch be pressed over 4 second. If it set to
“Instant Off”, the system will unconditional Power Off once the Power Switch be pressed.
5.6.14. Resume by Ring
An input signal on the serial Ring Indicator (RI) line (in other words, an incoming call on the modem) awakens the system from a soft off state.
5.6.15. Resume By Alarm
This allows you to have an unattended or automatic power up of your system. You may configure your system to power up at a certain time on a certain date by selecting Enabled to configure it.
5.6.16. Wake Up On LAN
This option specifies whether the computer responds to an incoming call or not. Wake-On Lan requires a PCI add-in network interface card with remote wakeup capabilities.
