CHAPTER 1 INTRODUCTION

1-1

The ATX BX2 mainboard is a high-performance personal computer
mainboard based on the Pentium® II processor. The Pentium® II processor
supports MMX

TM

(Multimedia Extension) technology .

The mainboard uses the highly integrated Intel® 82443BX AGP chipset to
support the PCI/ISA and Green standards, and to provide the Host/AGP
bridge. The Intel® 82371EB chipset integrates all system control functions
such as ACPI (Advanced Configuration and Power Interface). The ACPI
provides more Energy Saving Features for the OSPM(OS Direct Power
Management) function. The Intel® 82371EB chipset also improves the IDE
transfer rate by supporting Ultra DMA/33 IDE that transfers data at the rate
of 33MB/s.

The mainboard also supports the System Hardware Monitor Controller as an
optional function. This function includes: CPU /power supply/chassis fan
revolution detect, CPU/system voltage monitor, system temperature monitor ,
and chassis intrusion detect(optional).

2.1-2 CPU Core Speed Derivation Procedure

1 . The DIP Switch SW1 (1, 2, 3, and 4) is used to set the Core/Bus (Fraction)

ratio of the CPU. The actual core speed of the CPU is the Host Clock
Frequency multiplied by the Core/Bus ratio. For example:

If CPU Clock = 66MHz

Core/Bus ratio = 3. 5

then CPU core speed = Host Clock x Core/Bus ratio

= 66MHz x 3.5
= 233MHz

2 . The PCI Bus Clock is fixed at 33MHz.

SW1

CPU

Note: a. The CPU Bus Frequency is set at 66MHz or 100MHz by CPU

default.
b. If the mainboard support CPU Plug & Play, disregard this table
and go directly to BIOS Special Features Setup to set the CPU
speed.

CHAPTER 2 HARDWARE INSTALLATION

entered at the prompt.

Setup(default) The system will boot, but access to Setup will

be denied if the correct password is not entered
at the prompt.

PCI VGA Palette Snooping

Choose Disabled or Enabled. Some graphic controllers which are not
VGA compatible, take the output from a VGA controller and map it to their
display as a way to provide the boot information and the VGA compatibility .

However, the color information coming from the VGA controller is
drawn from the palette table inside the VGA controller to generate the proper
colors, and the graphic controller needs to know what is in the palette of the
VGA controller. To do this, the non-VGA graphic controller watches for the
Write access to the VGA palette and registers the snoop data. In PCI based
systems, where the VGA controller is on the PCI bus and a non-VGA graphic
controller is on an ISA bus, the Write Access to the palette will not show up
on the ISA bus if the PCI VGA controller responds to the Writes.

In this case, the PCI VGA controller should not respond to the Write. It
should only snoop the data and permit the access to be forwarded to the ISA
bus. The non-VGA ISA graphic controller can then snoop the data on the ISA
bus. Unless you have the above situation, you should disable this option.

Disabled (default) Disables the function

Enabled Enables the function

OS Selection for DRAM > 64MB

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 items allows you to determine the recovery time allowed for 8 bit
I/O. Choices are from NA, 1 to 8 CPU clocks.

Resources Controlled By

By Choosing “Auto”, the system BIOS will detect the system
resource and automatically assign the relative IRQ and DMA Channel for
each peripheral.

By Choosing “Manual”(default), the user will need to assign IRQ &
DMA for add-on cards. Be sure that there is no conflict for IRQ/DMA and I/
O ports.

Note: When choosing “Auto” you must be sure that all of the system
add-on cards are PnP type.

Reset Configuration Data

The system BIOS supports the PnP feature so the system needs to
record which resource is assigned and protect resources from conflict.
Every peripheral device has a node which is called ESCD. This node records
which resources are assigned to it. The system needs to record and update
ESCD to the memory locations. These locations (4K) are reserved at the
system BIOS.

If Disabled (default) is chosen the system’s ESCD will update only
when the new configuration varies from the last one.

If Enabled is chosen the system will be forced to update the system’s
ESCD. Then, this option willbe auto-set to Disable.

IRQ-3 assigned to : Legacy ISA

IRQ-4 assigned to : Legacy ISA

The above settings will be shown on the screen only if “Manual” is
chosen for the Resources Controlled By function.

Legacy is the term which signifies that a resource is assigned to the
ISA Bus and provides for non PnP ISA add-on card. PCI/ISA PnP signifies
that a resource is assigned to the PCI Bus or provides for ISA PnP add-on
cards and peripherals.

Assign IRQ for VGA

Lets the user choose which IRQ to assign for VGA card.

Assign IRQ for USB

Set to Enabled when USB port will be used. Set to Disable if the USB
port will not be used.

IDE Secondary Slave PIO

Auto/Mode0/Mode1-4

For these 4 IDE options, choose “Auto” to have the system BIOS
auto detect the IDE HDD operation mode for PIO access.

Note: Some IDE HDD can not operate at the responding HDD’s mode.
When the user has selected “Auto” and the system BIOS has
accepted the HDD response mode, the user may degrade the
HDD’s operation mode. Ex: IF the HDD reported it can operate in
mode 4 but it is not operating properly , the user will have to
manually change the operation mode to mode 3.

Choosing Mode 1-4 will have the system ignore the HDD’s reported
operation mode and use the selected mode instead.

Note:According to ATA specs. Mode 4 transfer rate is > Mode 3 > Mode 2

> Mode 1 > Mode 0. If the user’s HDD can operate at Mode 3 the user
can also select a slower Mode (i.e. Mode 0-2) but not a faster Mode (ie
Mode 4).

Description of the item on screen follows:

Configure SDRAM Timing by SPD

Enabling this option will set the SDRAM timing value to the value
provided by the DIMM SPD, otherwise, value will be set to the values you
set.

Note: It is recommended that under 100MHz, you use DIMM with SPD.

SDRAM RAS# to CAS# Delay

This operation decide the delay in assertion of CAS#(SCAS#) from
assertion of RAS#(SRAS#) in 66MHz. Under 66MHz CPU bus, set this
option to either 2 or 3 but for 100MHz CPU, it is recommended that this be
set to 3.

SDRAM RAS Precharge

This option defines the RAS# precharge requirements for the
SDRAM memory type in 66MHz clocks. Under 66MHz CPU bus, set this
option to either 2 or 3 but for 100MHz CPU, it is recommended that this be
set to 3.

SDRAM CAS# Latency

This option determines the CAS latency time parameter of SDRAM.
The settings are 2 clks or 3 clks. Under 66MHz CPU bus, set this option to
either 2 or 3 but for 100MHz CPU, it is recommended that this be set to 3.

SDRAM Leadoff Cmd Timing

This control the SDRAM command for CPU cycles. When this is
set to Auto, timing value is set on the value provided by SPD; 4 to 100MHz;
and 3 to 66MHz.

DRAM Integrity Mode

During ECC, this will enable the DRAM ECC mechanism that allows
single bit error detection and recovery . During EC mode, it will detect multi­bit errors but cannot perform correction.

DRAM Refresh Rate

This option is for setting the frequency of refreshing the DRAM.
A vailable settings are 15.6, 31.2, 62.4, 124.8, and 249.6 us.

Memory Hole

This option allows the end user to specify the location of a memory
hole. The cycle matching the selected memory hole will be passed to the
ISA bus. If Enabled, the selected hole is not remapped.

VGA Frame Buffer USWC

The Pentium® II processor supports the Uncacheable Speculatable
Write-Combining (USWC) memory type. The processor provides a write­combining with buffering strategy for write operation. This is useful for
frame buffering. Writing to USWC memory can be buf fered and combined in
the processors write-combining buffer (WCB). The WCBs are viewed as a
special purpose outgoing write buffers, rather than a cache. The WCBs are
written into memory to allocate a different address, or after executing a
serializing, locked, or I/O instructions.

During Enabled, this will enable the processor memory location
B000 and BFFF segment as USWC memory type.

PCI Frame Buffer USWC

The Pentium® II processor supports the Uncacheable Speculatable
Write-Combining (USWC) memory type. The processor provides a write­combining with buffering strategy for write operation. This is useful for
frame buffering. Writing to USWC memory can be buf fered and combined in
the processors write-combining buffer (WCB). The WCBs are viewed as a
special purpose outgoing write buffers, rather than a cache. The WCBs are
written into memory to allocate a different address, or after executing a
serializing, locked, or I/O instructions.

During Enabled, this will enable the processor memory location
from main memory to 4GB segment as USWC memory type.

USWC Write Post

Set this option to Enabled to use USWC(Uncacheable,
Speculatable, Write-Combined) memory . The settings are Enabled or
Disabled. The Optimal and Fail-Safe default settings are Disabled.

Graphics Aperture Size

This option determines the effective size of the graphics aperture
used in the particular P AC configuration. The AGP aperture is memory­mapped, while graphics data structure can reside in a graphics aperture. The
aperture range should be programmed as not cacheable in the processor
cache. Accesses with the aperture range are forwarded to the main memory ,
then PAC will translate the original issued address via a translation table
that is maintained on the main memory . The option allows the selection of
an aperture size of 4MB, 8MB, 16MB, 32MB, 64MB, 128MB, and 256MB.

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 items allows you to determine the recovery time allowed for 8
bit I/O. Choices are from NA, 1 to 8 CPU clocks.

16 Bit I/O Recovery Time

This items allows you to determine the recovery time allowed for 16
bit I/O. Choices are from NA, 1 to 4 CPU clocks.

USB Passive Release

During Enabled, this will allow the PIIX4® to use passive
release(look at PIIX4® Passive Release) while transferring control
information or data for USB transaction. During Disabled, PIIX4

®

will perform PCI accesses for USB without using passive release.

CHAPTER 4

AMI® BIOS USERS GUIDE

4-13

PIIX4® Passive Release

The PIIX4® ISA bridge support GAT (Guaranteed Access Time)
mode, which will now violate the spirit of the PCI specification. The systems
provides a programmable passive release mechanism to meet the required
master latencies. During Enabled, ISA masters may see long delays in
accessing PCI memory , including the main DRAM array . The ISA GA T mode
is also not supported during enable. ISA masters must honor IOCHRDY.

PIIX4® Delayed Transaction

During Enabled, the PIIX4® delay transaction mechanism is enabled
when the PIIX4® is the target of a PCI transaction. A read cycle from Host to
PCI is immediately retrived due to any pending PCI to DRAM cycle. During
Disabled, a read cycle from Host to PCI is waited until time-out due to any
pending PCI to DRAM cycle.

USB Function

Set this option to Enabled or Disabled the on-chip USB controller.
The Optional and Fail-Safe default settings are Disabled.

USB Keybd/Mouse Legacy Support

Set this option to Enabled or Disabled USB keyboard/mouse.
The Optional and Fail-Safe default settings are Disabled.
