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
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.

II or Deschutes Processor, from a system

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

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.

S.E.C. Cartridge Terminology

• Pentium® II or Deschutes Processor
The new enclosed card packaging technology is called a “Single Edge
Contact cartridge.” This is similar to previous names for packaging
technology such as PGA or TCP.

• Processor card
The green PCB (with or without components on it)

• Processor core
The silicon on the PLGA package on the PCB

• Cover
The plastic cover on the opposite side from the thermal plate.

• Slot 1
The slot that the S.E.C. cartridge plugs into, just as the Pentium® Pro
processor uses Socket 8.

• Retention mechanism
Formerly ‘retention module’ the dual posts, etc. that holds the cartridge
in place.

• Thermal plate
The heatsink attachment plate.

• Heat sink supports

The support pieces that are
mounted on the mainboard
to provide added support for
heatsinks.

The L2 cache (TagRAM, PBSRAM)
components keep standard industry
names.

The Pentium

II or Deschutes Processor
is the first product to utilize the S.E.C.
cartridge technology and Slot 1
connector. Unless otherwise noted, any
references to “Pentium® II Processor,”

Introduction EP-BXT

EP-BXT Form-Factor

The EP-BXT is designed with ATX form factor - the new 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, etc.) to systems. This will help systems integrators differentiate their products
in the marketplace, and better meet your needs.

• Smaller size promotes a smaller system size.

• I/O shield does not need to be retooled in an ATX 2.01 or later. Mainboard could

be used in an ATX 2.01-compliant.

• A smaller power supply cam be used. High integration on mainboard reduces the

system costs.

The EP-BXT 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-BXT 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 the
button, and the other is the "Soft Off" function (coming from the EP-BXT’s onboard
circuit controller) that can be controlled by the operating system. Windows 95/98 will
control this when the user clicks that they are ready to Shutdown the system.

Note: Based on the implementation of Intel 440BX PCIset, EP-BXT is able to
provide two host bus frequencies -- either 66 or 100MHz for Slot1 processor
and memory operating. The default is set at 100MHz once Pentium® II
processor to be mounted onto this mainboard. 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.

System Memory Configuration

Memory Layout

The EP-BXT supports (3) 168-pin DIMMs (Dual In-line Memory Module). The
DIMMs can be either EDO (Extended Data Out) or SDRAM (Synchronized
DRAM).

• We recommend using SDRAM DIMM can not mixing

with EDO DIMM modules together at 66MHz.

• The EDO DIMM only support pentium
support Deschutes Processor at 100MHz.

• 256MB only Support Registered synchronous DRAM Memory
Modules. The Registered SDRAM DIMM do not mix with SDRAM
DIMM modules together.

• 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 Intel’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.

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-BXT 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.

JP13 K eyboard P ower-O N Function Selection

1-2 : E nabled
2-3 : Disabled (Default)

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 counting
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
to the 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-BXT
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.

Figure 6: PCI Configuration Setup

PNP OS Installed: Do you have a PNP OS installed on your system. The default is
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

Page 4-16

BIOSEP-BXT

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 D000H­D3FFFH 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.

Assign IRQ For USB: This item allows BIOS to assign whether IRQ is with USB
or not. If you have not connect the USB device. Can release the IRQ for other
device.

4-9 IDE HDD Auto Detection

The “IDE HDD auto detection” utility is a very useful tool, especially when you do
not know which kind of hard disk type you are using. You can use this utility to detect
the correct disk type installed in the system automatically. But now you can set
HARD DISK TYPE to Auto in the STANDARD CMOS SETUP. You don’t need
the “IDE HDD AUTO DETECTION” utility. The BIOS will Auto-detect the hard
disk size and model on display during POST.

Figure 8: IDE HDD Auto Detection

NOTE: HDD Modes

The Award BIOS supports 3 HDD modes : NORMAL, LBA & LARGE NORMAL
mode

Generic access mode in which neither the BIOS nor the IDE controller will make
any transformations during accessing.

The maximum number of cylinders, head & sectors for NORMAL mode are.

1024, 16 & 63

x no. Head ( 16)
x no. Sector ( 63)

528 Megabytes

Page 4-24

BIOSEP-BXT

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 (1024)
x no. Head ( 255)
x no. Sector ( 63)
x bytes per sector ( 512)

8.4 GigaBytes

LARGE mode: Extended HDD access mode supported by Award Software.
Some IDE HDDs contain more than 1024 cylinder without LBA support (in some

cases, user do not want LBA). The Award BIOS provides another alternative to
support these kinds of LARGE mode.

CYLS HEADS SECTOR MODE

1120 16 59 NORMAL
560 32 59 LARGE

BIOS tricks DOS (or other OS) that the number of cylinders is less than 1024 by
dividing it by 2. At the same time, the number of heads is multiplied by 2. A reverse
transformation process will be made inside

INT 12h in order to access the right HDD address!
Maximum HDD size:

no. Cylinder (1024)
x no. Head ( 32)
x no. Sector ( 63)
x bytes per sector ( 512)

1 GigaByte

Page 4-25

BIOS EP-BXT

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
Standard mode. UNIX can support drives larger than 528MB.

4-10 HDD Low Level Format

Interleave: Select the interleave number of the hard disk drive you wish to perform
a low level format on. You may select from 1 to 8. Check the documentation that
came with the drive for the correct interleave number, or select 0 for automatic
detection.

Auto scan bad track: This allows the utility to scan first then format by each track.
Start: Press<Y>to start low level format.

4-11 Save & Exit Setup

The “SAVE & EXIT SETUP” option will bring you back to the boot up procedure
with all the changes you just recorded in the CMOS RAM.

4-12 Exit Without Saving

The “EXIT WITHOUT SAVING” option will bring you back to normal boot up
procedure without saving any data into CMOS RAM.

All old data in the CMOS will not be destroyed.

CPU Clock Frequency Selection In BIOS Setting.

There is a special function for CPU over-clocking requirement which can be chosen and set
by BIOS or set by JP3(The undocumented jumper setting from 103MHz to 133MHz), please
refer to the following steps for adjustment.

1. Enter the BIOS CMOS setup program. (If your system was operated at 66MHz)

2. Choose Chipset Features Setup in main menu.

3. Use Page down (or+) / Page up (or -) to choose CPU clock frequency as one of 66.8,
75MHz, 83.3MHz or by JP3 to setting 103MHz to 124MHz.
(Note: There are 66.8, 75 and 83.3MHz for 66MHz pentium II CPU CLOCK frequency show
only).

4. Press Save & Exit setup to complete BIOS setting.

If screen becomes blank or system cant boot anymore after above setting. that means your
CPU couldnt be capable of supporting overclock, and you have to follow the steps below to
recover the CPU clock frequency.

Step 1: Power the system off. (J3 PW-ON)

Step 2: Press <INS> (Insert) key while powering on the system, system will function with

66MHz external frequency at this moment which depends on what kind of
CPU on board.

Step 3: Please choose lower frequency and try again.

Warning:

We do not guarantee all CPUs can be over-clocked (When the undocumented set by BIOS[75
and 83.3MHz] or by JP3[103 to 133MHz]), it depends on CPU design and the peripherals you
are using; its vitally important to use faster peripherals (faster SDRAM, AGP, I/O card...) to
come with the higher CPU clock frequency.
Please set apporpriate CPU CLOCK frequency to make the system stable.
