Introduction EP-61BXA-M

Overview

Pentium II or Deschutes Processor

The Pentium

®

II or Deschutes Processor (The Deschutes Processor as 300/

100MHz, 350/100MHz, 400/100MHz and 450/100MHz speed with 512K-L2 cache

Versions.) is the follow-on to the Pentium

®

Processor. The Pentium

®

II or

Deschutes Processor, like the Pentium

®

Pro processor, implements a Dynamic

Execution micro-architecture -- a unique combination of multiple branch prediction, data flow analysis, and speculative execution. This enables the Pentium

®

II Processor to deliver higher performance than the Pentium

®

processor, while maintaining binary compatibility with all previous Intel architecture processors.

A significant feature of the Pentium

®

II or Deschutes Processor, from a system perspective, is the built-in direct multiprocessing support. In order to achieve multiprocessing, and maintain the memory and I/O bandwidth to support it, new system designs are needed. For systems with dual processors, it is important to consider the additional power burdens and signal integrity issues of supporting multiple loads on a high speed bus. The Pentium

®

II or Deschutes Processor card supports both uni-processor and dual processor implementations.

The Pentium

®

II or Deschutes Processor utilizes Single Edge Contact (S.E.C.)

(Figure 1) cartridge packaging technology. The S.E.C. cartridge allows the L2 cache to remain tightly coupled to the processor, while maintaining flexibility when implementing high performance processors into OEM systems. The second level cache is performance optimized and tested at the cartridge level. The S.E.C. cartridge utilizes surface mounted core components and a printed circuit board with an edge finger connection. The S.E.C. cartridge package introduced on the Pentium

®

II Processor will also be used in future Slot 1 processors.

The S.E.C. cartridge has the following features: a thermal plate, a cover and a PCB with an edge finger connection. The thermal plate allows standardized heatsink attachment or customized thermal solutions. The thermal plate enables a reusable heatsink to minimize fit issues for serviceability, upgradeability and replacement. The full enclosure also protects the surface mount components. The edge finger connection maintains socketabilty for system configuration. The edge finger connector is denoted as ‘Slot 1 connector’ in this and other documentation.

The entire enclosed product is called the Pentium

®

II or Deschutes Processor. The

Page 1-2


packaging technology and each of the physical elements of the product are referred to using accurate technical descriptions. This allows clear reference to the products as just a processor. This is the model used in past packaging technologies like PGA,

TCP, PQFP, DIP, etc.

Accelerated Graphics Port

(AGP or A.G.P.)

Typically, 3D graphics rendering requires a tremendous amount of memory, and demands ever increasing throughput speed as well. As 3D products for the personal computer become more and more popular, these demands will only increase. This will cause a rise in costs for both end users and manufacturers. Lowering these costs as well as improving performance is the primary motivation behind AGP. By providing a massive increase in the bandwidth available between the video card and the processor, it will assist in relieving some of these pressures for quite sometime.

Hardware Monitoring

Hardware monitoring allows you to monitor various aspects of your systems operations and status. These include features such as CPU temperature, voltage and fan

RPM’s.

Desktop Management Interface

(DMI)

DMI, or Desktop Management Interface, is a BIOS level method for monitoring specific BIOS related hardware features. It allows the BIOS to collect and store information specific to the system, so that vendors and system integrators will have greater access to information regarding system configuration and design. This allows for better troubleshooting, migration planning, and upgradeability decision making.

EP-61BXA-M Form-Factor

The EPoX EP-61BXA-M is designed with ATX form factor - the latest industry standard of chassis. The ATX form factor is essentially a Baby-AT baseboard rotated 90 degrees within the chassis enclosure and a new mounting configuration for the power supply. With these changes the processor is relocated away from the expansion slots, allowing them all to hold full length add-in cards. ATX defines a double height aperture to the rear of the chassis which can be used to host a wide range of onboard I/O. Only the size and position of this aperture is defined, allowing

PC manufacturers to add new I/O features (e.g.; TV input, TV output, joystick, modem, LAN, audio, etc.) to systems. This will help systems integrators differentiate their products in the marketplace, and better meet your needs.

•

By integrating more I/O down onto the board and better positioning the hard drive and floppy connectors material cost of cables and add-in cards is reduced.

•

By reducing the number of cables and components in the system, manufacturing time and inventory holding costs are reduced and reliability will increase.

•

By using an optimized power supply, it's possible to reduce cooling costs and lower acoustical noise. An ATX power supply, which has a side-mounted fan, allows direct cooling of the processor and add-in cards making a secondary fan or active heatsink unnecessary in most system applications.

Power-On/Off (Remote)

The EP-61BXA-M has a single 20-pin connector for ATX power supplies. For ATX power supplies that support the Remote On/Off feature, this should be connected to the systems front panel for system Power On/Off button. The systems power On/

Off button should be a momentary button that is normally open.

The EP-61BXA-M has been designed with “Soft Off" functions. You can turn Off the system from one of two sources: The first is the front panel Power On/Off button, and the other is the "Soft Off" function (coming from the EP-61BXA-M’s onboard circuit controller) that can be controlled by the operating system. Windows

95 will control this when the user clicks that they are ready to Shutdown the system.

Installation EP-61BXA-M

Note: Based on the implementation of Intel 440BX PCIset, EP-61BXA-M is able

to provides two host bus frequencies -- either 66 or 100MHz for Slot1 processor and memory operating. Automatically, the default is at 66MHz once Pentium

®

II processor to be mounted onto this mainboard. In case of Deschutes processor, it is self-adjusted to 100MHz without any manual modification required. However, no matter what kind of Slot1 processor you installed, it should come with right memory modules for normal and stable operation. For example, if you install a Deschutes processor, you should use the SDRAM module with 100MHz based(or above) to match the CPU speed. Furthermore, one thing you may need to bear in mind, before the CPU installation, it is anyway our advice to use JP3 and set up right speed of Slot1 processor at any time. You may feel like to know about AGP interface, which always runs under 66MHz no matter what frequency of processor you installed.

System Memory Configuration

Memory Layout

The EP-61BXA-M supports (3) 168-pin DIMMs (Dual In-line Memory Module).

The DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized

DRAM). The DIMMs may be installed using just one chip.

•

•

We recommend using SDRAM DIMM can not mixing with EDO DIMM modules.

The EDO DIMM only support pentium

®

II Processor at 66MHz, not support Deschutes Processor at 100MHz.

• We recommend when installed the 100MHz Deschutes Processor using DIMM SDRAM must be 125MHz (-8ns) bus speed. If used

100MHz (-10ns) SDRAM may be critical timing for the motherboard.

• About the “PC/100 SDRAM spec.” information you may visit Inte’s home page at: http//developer.intel.com/design/pcisets/memory/index.htm

DIMM SDRAM may be 83MHz (-12ns), 100MHz (-10ns) or •

125MHz (-8ns) bus speed.

Section 3-3

Installing a Pentium II or Deschutes Processor

The EP-61BXA-M uses the Single Edge Contact (SEC) slot for a Pentium II processor packaged in an SEC cartridge. The SEC slot is not compatible with other non-

Pentium II processors.

Please have ready the following list of components so that we may install the processor onto the motherboard.

1.

Heat sink support (top/bottom piece)

2.

Pentium II processor heat sink

3.

Intel Pentium II Processor

OK, now that you have all of your components ready, we can start.

First, please refer to figure 8 below, and follow the direction to lift up the fixed foldable pentium

®

II Retention Mechanism. This pre-installed device is designed for you to install Pentium ® II CPU more easier and to avoide any damage on the board due to overtightening the four screws.

One thing must be kept in your mind that please make sure to lift upright the foldable parts of the Retention module to fit and install CPU properly.

Figure 8

Now we are going to install the heatsink support base piece (figure 9) onto the motherboard. There is both a large and small hole (figure 10) so that the base will only fit in one direction. This piece needs to be pushed into the holes firmly until it is seated.

Now we are ready to install the SEC Cartridge (Pentium II Processor) into the

Retention Module. The SEC Cartridge is mounted by sliding the SEC Cartridge into the Retention Module and letting it slide all the way down. Once it reaches the

Page 3-8


bottom make sure you press firmly on SEC cartridge to firmly secure into the Slot 1

Socket.

Now we need to secure the heatsink with the top half of the support (figure 11).

Take the top piece of the support and slide it into the bottom fin (figure 11) on the heatsink and then push forward until it clips into the bottom base (figure 9) that is already there (figure 11).

External Modem Ring-in Power

ON and Keyboard Power ON

Functions (KBPO)

On the basis of bounded functions in I/O chipset, the two serial ports are able to support the External Modem Ring-in Power ON function. Once users connect the external modem to COM1 or COM2, the EP-61BXA-M mainboard allows users to turn on their system through the remote and host's dial-up control.

Exclusive Keyboard Power ON Function

To innovate a unique feature to benefit users, we devoted the easiest and most convenient way to turn on your system based on the the ATX power supply.

How to work with it

Step 1:Please check JP13 at the position 1-2 after you finished the system installation.

1 -2 : E n a b led

2 -3 : D is a b led (D efa u lt)

Step 2:Push the momentary switch (J3 PW-ON) to turn on your system and then push again to hold for more than 4 seconds to turn it off affter counted memory as soon as you turn it on.

Step 3:You can enjoy the Keyboard Power ON function (KBPO) by pressing any 1

key, Hot key (Ctrl-F1, F2.....F12), Password (A maximum of 5 charac ters can be entered.) and BUTTON only to turn on your system. Please refer tothe BIOS Integrated peripherals setup for detail (Page 4-23).The

BIOS Default is keyboard Hot key <Ctrl> - <F1> to turn on the system.

Your system will be turned on automatically, after releasing the keys. To power off you system, you can use the Soft-OFF function under Windows 95.

Page 3-12


Notes:

1.Intel ATX version 2.0 specification has recommended you use the power supply with 0.72A(720mA) in 5.0VSB. With our EP-61BXA-M mainboard, the 5.0VSB standby power only has to be > = 0.1A

(100mA) then you can enjoy this unique benefit. However, the ATX power supply which is < 0.1 (100mA) is still applicable to your system by placed JP13 at the position 2-3 to disable this feature.

AWARD BIOS SETUP

BIOS Instructions

Award’s ROM BIOS provides a built-in Setup program which allows user to modify the basic system configuration and hardware parameters. The modified data will be stored in a battery-backed CMOS, so that data will be retained even when the power is turned off. In general, the information saved in the CMOS RAM will stay unchanged unless there is a configuration change in the system, such as hard drive replacement or a device is added.

It is possible for the CMOS battery to fail, this will cause data loss in the CMOS only. If this does happen you will need to reconfigure your BIOS settings.

To enter the Setup Program :

Power on the computer and press the <Del> key immediately, this will bring you into the BIOS CMOS SETUP UTILITY.

No.

Yes: Select if you are using a PNP OS

No: Select if your OS does not support PNP.

Resources Controlled By: Who controlled the system PNP/PCI resources.

The default is Manual.

Manual: PNP Card’s resources will be controlled manually. You can set which IRQ-X and DMA-X are assigned to PCI/ISA PNP or Legacy ISA

Cards.

Auto: If your ISA card and PCI card are all PNP cards, BIOS will assign the interrupt resource automatically.

Reset Configuration Data: This setting allows you to clear ESCD data.

The default is Disabled

Disabled: Normal Setting.

Enabled: If you have plugged in some Legacy cards to the system and they were recorded into ESCD (Extended System Configuration Data), you can set this field to Enabled in order to clear ESCD.

PCI IDE IRQ Map To: This item allows the user to configure the system for the type of IDE hard disk controller in use. By default, the BIOS assumes that the hard drive controller is an ISA device rather than a PCI controller. If you are using a PCI controller, then you will need to change this to specify which PCI slot has the controller and which PCI interrupt (A, B, C, or D) is associated with the connected IDE devices.

The default value is PCI-AUTO. This will allow the system to automatically configure the IDE devices.

Used MEM base addr: The Used MEM base addr (CB00, CC00, D000, D400,

D800, DC00) and Used MEM Length (8K, 16K, 32K, 64K) are used to support some specific ISA Legacy cards with requested memory space below 1M address.

Now with these two functions, users can define where the used memory address is located and its length of the legacy area that is used by the legacy device to avoid the memory space conflict. For example, if you select “D000” for Used MEM base addr” and “16K” for “Used MEM Length”, that means the address region D000H-

D3FFFH is occupied by ISA legacy cards, and thus BIOS will not assign this region for PnP/ISA and PCI cards.

The default is N/A.

528 Megabytes

If user set his HDD to NORMAL mode, the maximum accessible HDD size will be

528 Megabytes even though its physical size may be greater than that!

LBA (Logical Block Addressing) mode: A new HDD accessing method to overcome the 528 Megabyte bottleneck. The number of cylinders, heads & sectors shown in setup may not be the number physically contained in the HDD. During

HDD accessing, the IDE controller will transform the logical address described by sector, head & cylinder into its own physical address inside the HDD. The maximum

HDD size supported by LBA mode is 8.4 GigaBytes which is obtained by the following formula: no. Cylinder x no. Head x no. Sector x bytes per sector

Note: To support LBA or LARGE mode of HDDs, there must be some software involved. All the software is located in the Award HDD Service

Routine (INT 13h). It may fail to access a HDD with LBA (LARGE) mode selected if you are running under an Operating System which replaces the whole INT 13h.

UNIX operating systems do not support either LBA or LARGE and must utilize the

EP-61BXA-M DMI Access

Section 5

DMI ACCESS

DMI Access

DMI, or desktop Management Interface, is a feature that is able to auto-detect and record information about your computer system. This information is used by computing professionals to accurately determine your system configuration and to diagnose and resolve problems.

The computer’s BIOS will detect and record as much information as it is able to, and will store that information in a special location in the BIOS.

The DMI configuration utility will allow system integrators to add information that the

BIOS cannot detect, such as model and brand of motherboard and other components.

This information cannot be detected by the bios and must be added by the system integrator or vendor.
