The Choices: Auto (default), Yes, No.

Ac Loss Auto Res tar t

This field determines the action the system will automatically take when power is restored
to a system that had lost power previously without any subsequent manual intervention.
There are 3 sources that provide current to the CMOS area that retains these Power-On
instructions; the motherboard battery (3V), the Power Supply (5VSB), and the Power
Supply (3.3V). While AC is not supplying power, the motherboard uses the motherboard
battery (3V). If AC power is supplied and the Power Supply is not turned on, 5VSB from
the Power Supply is used. When the Power Supply is eventually turned on 3.3V from the
Power Supply will be used.
There are 3 options: “Former-Sts”, “On”, “Off”.
“Off” (default) Means always set CMOS to the “Off” status when AC power is lost.
“On” Means always set CMOS to the “On” status when AC power is lost
“F orme r-Sts” Mean s to m aintain th e last st atus of t he CM OS wh en AC p ower is lost.

For example: If set to “Former-Sts” and AC power is lost when system is live, then after
AC power is restored, the system will automatically power on. If AC power is lost when
system is not live, system will remain powered off.

7 PnP/PCI Configurations

This section describes configuring the PCI bus system. PCI, or Personal Computer
Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed
of the CPU itself uses when communicatin g w ith its own special components. This section
covers some very technical items and it is stron gly recommended that only experienced
users should make any changes to the default settings.

Figure 7: PnP/PCI Configurations



PNP OS Installed

When set to YE S, B IOS wil l only initialize the P nP c ards used for th e boot sequ ence
(VGA, IDE, SCSI). T he rest of the cards will be initialized by the PnP operating system

lik e W ind ow™ 95. When set to NO , BIOS w ill initia l ize all th e PnP card s. For non-P nP
operating systems (DOS, Netware™), this option must set to NO.

The Choices: No (default), Yes.

Reset Configuration Data

The system BIOS supports the PnP feature which requires the system to record which
resources are assigned and protects resources from conflict.

Every peripheral device has a node, which is called ESCD. T his 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 in the system BIOS. If the Disabled
(default) option is chosen, the system‘s ESCD will update only when the new

32

K8T89-A7 BIOS Setup

configuration varies from the last one. If the Enabled option is chosen, the system is forced
to update ESCDs and then is automatically set to the “Disabled” mode.

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 ass igned to the ISA Bus and provides
non-PnP ISA add-on cards. PCI / ISA P nP signifies that a resource is assigned to the PCI
Bus or provides for ISA PnP add-on cards and peripherals.

The Choices: Disabled (default), Enabled.

Resources Controlled By

By Choosing “Auto(ESCD)” (default), the system BIOS will detect the system resources
and automatica lly assign the relat ive IRQ and DMA channel for each peripheral. By
Choosing “Manual”, the user will need to assign IRQ & DMA for add-on cards. Be sure
that there are no IRQ/DMA and I/O port conflicts.

IRQ Resources

This submenu will allow you to ass ign each system interrupt a type, depending on the type
of device using the interrupt. When you press the “Press Enter” tag, you will be directed to
a submenu that will allow you to configure the system interrupts. This is only
configurable when “Resources Controlled By” is set to “Manual”.

IRQ-3 assigned to PCI Device
IRQ-4 assigned to PCI Device

IRQ-5 assigned to PCI Device
IRQ-7 assigned to PCI Device
IRQ-9 assigned to PCI Device

IRQ-10 assigned to PCI Device
IRQ-11 assigned to PCI Device
IRQ-12 assigned to PCI Device
IRQ-14 assigned to PCI Device

PCI / VGA Palette Snoop

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 boot
inf orma tio n and VGA comp atibilit y.

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 con troller watches for the W rite access to the VGA palette and registers the sn oop
data. In PCI based systems, w here the VGA contro ller is on the P CI b us 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 Write.

In this c ase, the P CI VGA controller shou ld not respond to the Write, it shou ld on ly snoop
the data an d permit the acc ess to be fo rwa rded to the ISA bus. T he 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.
