2.2 PCI and ISA Slots
There are 5 PCI slots and 3 ISA slots. All PCI slots can be used as master.
But since the 1st and 5th PCI slots share the same bus master signal, only
one of these slots can be used as a master at a time; which means that if a
bus master card is installed in PCI slot 1, PCI Slot 5 can only accomodate a
slave card, and vice versa.
2-10
Note: 1 . You can only use a 3.3 V PCI Card, if the power supply you’re
using is an A TX power supply w/ 3.3V.
2. PCI Slot 1 to PCI Slot 5 IDSEL is AD_24(Device Num = 0DM) to
AD_28(Device Num = 11H) respectively.

This category allows you to limit access to the system and Setup,
or just to Setup.
System The system will not boot and access to Setup
will be denied if the correct password is not
entered at the prompt.
Setup(default) The system will boot, but access to Setup will
be denied if the correct password is not entered

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 . T o 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 W rite Access to the palette will not show up
on the ISA bus if the PCI VGA controller responds to the W rites.
In this case, the PCI VGA controller should not respond to the W rite.
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

Auto Configuration
Choosing Enabled (default) will automatically configure chipset
features using default settings. Choose Disable to customize setup.
DRAM Timing
Sets the DRAM speed at 70ns (default) or 60ns. It will set the
speed of the EDO/FP DRAM.
DRAM Leadoff Timing
To be able to change the setting, Auto configuration must be
disable. If the Bus Clock is 75MHz set it to 11/7/4, and if the Bus Clock is 66/
60/55 MHz set it to 10/6/4. Default setting is 10/6/4.
DRAM Read Burst (EDO/FP)
Under Auto config. the BIOS will identify which type of DRAM is
being used. Choose the setting accordingly. To customize, use this option
which sets the Read Burst time for accessing the DRAM. The timing used
depends on the type of DRAM and access time being used. The settings are
x222/x333, x333/x444, or x444/x444.
Note: If the user chooses DRAM Read Burst (EDO/FP): x333/x444 it signi-
fies that:
a. 60ns EDO with 75 MHz Bus Clock is set at x333, if the Bus Clock is
66/60/55 MHz, then it is set at x222.
b. 60ns FP with 75 MHz is set at x444, if the Bus Clock is 66/60/55,
then it is set at x333.
c. 70ns EDO and FP DRAM must increase the burst time. So you
must set x222 to x333 and x333 to x444.
DRAM Write Burst Timing
This option chooses the W rite Burst Timing for accessing DRAM.
See: DRAM Read Burst Option. Choose x222/x333/x444.

CHAPTER 3 AWARD® BIOS SETUP
Fast EDO Lead Off
Under Auto config. the BIOS will identify which type of DRAM is
being used. Choose the setting accordingly. To customize, use this option.
Choose Enable or Disable. If the system is using EDO DRAM, choose
enable. But if the system is using both EDO and FP DRAM, choose Disable.
Refresh RAS# Assertion
The settings are 4 Clks or 5 Clks. Using 60 ns DRAM at 75 Mhz Bus
Clock must be set to 5 Clks, while 66/60/55 Mhz Bus Clock must be set to 4
Clks. But if you use 70 ns DRAM, it must be set to 5 Clks.
Fast RAS to CAS Delay
The settings are 2 or 3. 2 RAS to CAS delay is set to 2 clock, while
3 RAS to CAS delay is set to 3 clock. The clock is dependent with the
DRAM Timing and Bus Clock.
DRAM Page IDLE Timer
The settings are 2 Clks, 4 Clks, 6Clks, or 8 Clks. Default settings is 2
Clks.
DRAM Enhanced Paging
Choose Enable(default) or Disable.
Fast MA to RAS# Delay
The settings are 1 Clks or 2 Clks(default). During 1T , one bus clock
is allowed, while 2T allows two bus clock for MA address setup time to
RAS assertion. This is also dependent on DRAM Timing.
SDRAM (CAS Lat/RAS-to-CAS)
The settings are 3/3 or 2/2. This option is for SDRAM CAS latency
time and RAS# to CAS# delay time. The default setting is 3/3.

CHAPTER 3 AWARD® BIOS SETUP
SDRAM Speculative Read
The settings are enable or disable. If you only use One Bank for
SDRAM and there’s no EDO or FP mix together, the setting is Enable. If two
banks are used by SDRAM, it will automatically be set to disable. The
default setting is enable.
System BIOS Cacheable
By choosing Disabled (default) the system BIOS will be shadowed
into DRAM only . Enabled will have the system BIOS shadowed and
cacheable.
Video RAM Cacheable
Same as system BIOS Cacheable
8-bit I/O recovery time: 1/2/3/4/5/6/7/NA
16-bit I/O recovery time: 1/2/3/NA
Choose the recovery time for 8-bit and 16-bit I/O cycles
respectively.
Note: NA is not available and so the recovery time of 3.5 SYSCLK will be
inserted.
Memory Hole At 15M-16M
Choosing Enabled will enable a memory hole in the DRAM space.
The CPU cycle matching the enabled hole will be passed on to the PCI. PCI
cycles matching an enabled hole are ignored. Disabled (default) will disable
this function.
Note: A selected (Enabled) hole is not remapped.
PCI 2.1 Compliance
The Settings are Enable or Disable. During Enable, those PCI addon cards with PCI 2.1 compliance will perform better . But some PCI card
does not meet PCI 2.1 compliance, so the default setting is Disabled.

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.

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.
PCI IDE IRQ Map To
PCI-Auto: This setting is for off-board PCI IDE card and is
fully compatible with PCI specifications.
PCI-Slot 1-5: This setting is used if off-board PCI IDE card is
not fully compatible with PCI specifications.
You must specify which PCI slot the PCI IDE
Card is installed in.
ISA: This setting is used if the off-board PCI IDE
card uses an edge trigger and IRQ routes
directly to the ISA Bus.
Note: The user will need to disable the on-board on-chipset PCI IDE
controller when installing off-board PCI IDE add-on cards. (See the
INTEGRA TED PERIPHERALS SETUP) These two options choose
the primary and secondary IDE Channel interrupts when the user
installs off-board PCI IDE add-on cards.

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 A TA 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).
On-Chip Primary PCI IDE
Enabled/Disabled
On-Chip Secondary PCI IDE
Enabled/Disabled The system provides for a On-Board
On-Chipset PCI IDE controller that
supports Dual Channel IDE (Primary
and Secondary). A maximum of 4 IDE
devices can be supported. If the user
install the Off-Board PCI IDE controller
(i.e. add-on cards), the user must
choose which channels will be disabled.
This will depend on which channel will
be used for the Off-Board PCI IDE addon card.

CHAPTER 3 AWARD® BIOS SETUP
PCI Slot IDE 2nd Channel
Enabled/Disabled Choosing Enabled will allow the system
to access the 2nd IDE channel without a
device driver. If the Of f-Board PCI IDE
add-on card is installed, the 2nd IDE
channel will need to be used.
Onboard FDD Controller
Enabled/Disabled The system has an on-board Super I/O
chip with a FDD controller that supports
2 FDDs for 360K/720K/1.2M/1.44M/
2.8M. Choose “Enabled” to use the onboard FDD controller for accessing the
FDD. Otherwise choose “Disabled” to
use the of f-board FDD controller .
Onboard Serial Port 1
Disabled/(3F8/IRQ4)/(2F8/IRQ3)/ (3E8/IRQ4)/(2E8/IRQ3)
Onboard Serial Port 2
Disabled/(3F8/IRQ4)/(2F8/IRQ3)/(3E8/IRQ4)/(2E8/IRQ3)
The system has an On-board Super I/O chipset with 2 serial ports.
The On-board serial ports can be selected as:
Disabled
3F8/IRQ4 COM 1 uses IRQ4
2F8/IRQ3 COM 2 uses IRQ3
3E8/IRQ4 COM 3 uses IRQ4
2E8/IRQ3 COM 4 uses IRQ4
Note: Because the ISA Bus Interrupt accepts low to high edge trigger, the
interrupt request line cannot be shared by multiple sources. If an offboard ISA add-on card with a serial port is installed the user may have
to disable the on-board serial port because it will conflict with IRQ
request line for the off-board serial port.

Plug and Play Aw are O/S
Set this option to Yes if the operating system in this computer is
aware of and follows the Plug and Play specification. Currently , only
Windows® 95 is PnP-aware. The settings are Y es or No. The Optimal and
Fail-Safe default settings No.
Clear NVRAM
During Enabled, this option will clear the NVRAM on every boot.
PCI Latency Timer (PCI Clocks)
This option specifies the latency timings (in PCI clocks) for all PCI
devices on the PCI bus. The settings are 32, 64, 96, 128, 160, 192, 224 or 248.
The Optimal and Fail-Safe default settings are 64.
PCI VGA Palette Snoop
When this option is set to Enabled, multiple VGA devices operating
on different buses can handle data from the CPU on each set of palette
registers on every video device. Bit 5 of the command register in the PCI
device configuration space is the VGA Palette Snoop bit (0 is disabled). For
example, if there are two VGA devices in the computer (one PCI and ISA)
and the Bit settings are:
Disabled - Data read and written by the CPU is only dircted to the
PCI VGA device’ s palette registers.
Enabled - Data read and written by the CPU is directed to the
both the PCI VGA device’ s palette registers and the
ISA VGA device palette registers, permitting the
palette registers of both devices to be identical.
This option must be set to Enabled if an ISA adapter card requires
VGA palette snooping. The settings are Enabled or Disabled. The Optimal
and Fail-Safe default settings are Disabled.

PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the
PCI local bus includes a bus mastering capability . The settings are Enabled
or Disabled. The Optimal and Fail-Safe default settings are Disabled.
Offboard PCI IDE Card
This option specifies if an offboard PCI IDE controller adapter card
is installed in the computer . You must specify the PCI expansion slot on the
mainboard where the offboard PCI IDE controller is installed. If an offboard
PCI IDE controller is used, the onboard IDE controller is automatically
disabled. The settings are Auto(AMI® BIOS automatically determines where
the offboard PCI IDE controller adaper card is installed), Slot1, Slot2, Slot3 or
Slot4. The Optimal and Fail-Safe settings are Auto.
If an offboard PCI IDE controller adapter card is installed in the

DMA Channel 0/DMA Channel 1/DMA Channel 3/DMA
Channel 5/DMA Channel 6/DMA Channel 7
These options specify the bus that the specified DMA channel is
used. These options allow you to reserve DMAs for legacy ISA adapter
cards.
These options determine if AMI®
BIOS should remove a DMA from
the available DMAs passed to devices that are configurable by the system
BIOS. The available DMA pool is determined by reading the ESCD
NVRAM. If more DMAs must be removed from the pool, the end user can
use these options to reserve the DMA by assigning an ISA/EISA setting to
it.
IRQ3/IRQ4/IRQ5/RQ7/IRQ9/IRQ10/IRQ11/IRQ14/IRQ15
These options specify the bus that the specified IRQ line is used
on. These options allow you to reserve IRQs for legacy ISA adapter cards.
These options determine if AMI® BIOS should remove an IRQ from
the pool of available IRQs passed to devices that are configurable by the
system BIOS. The available IRQ pool is determined by reading the ESCD
NVRAM. If more IRQs must be removed from the pool, the end user can use
these options to reserve the IRQ by assigning an ISA/EISA setting to it.
Onboard I/O is configured by AMI® BIOS. All IRQs used by onboard I/O
are configured as PCI/PnP. If all IRQs are set to ISA/EISA and IRQ14 and 15
are allocated to the onboard PCI IDE, IRQ9 will still be available for PCI and
PnP devices, because at least one IRQ must be available for PCI and PnP
devices. The settings are ISA/EISA or PCI/PnP . The Optimal and Fail-Safe
default settings are IRQ3 through 7 are ISA/EISA. The Optimal and Fail-Safe
default settings PCI/PnP.
