setting is "64." Select "32" to set the PCI latency to 32 PCI clock cycles.
Select "64" to set the PCI latency to 64 PCI clock cycles. Select "96" to set
the PCI latency to 96 PCI clock cycles. Select "128" to set the PCI latency to
128 PCI clock cycles. Select "160" to set the PCI latency to 160 PCI clock
cycles. Select "192" to set the PCI latency to 192 PCI clock cycles. Select
"224" to set the PCI latency to 224 PCI clock cycles. Select "248" to set the
PCI latency to 248 PCI clock cycles.
Allocate IRQ to PCI VGA
Set this value to allow or restrict the system from giving the VGA adapter
card an interrupt address. The options are Yes and No.
PCI IDE BusMaster
Set this value to allow or prevent the use of PCI IDE busmastering. Select
"Enabled" to allow AMI BIOS to use PCI busmaster for reading and writing to
IDE drives. The options are "Disabled" and "Enabled".
Offboard PCI/ISA IDE Card
This option allows the user to assign a PCI slot number to an Off-board PCI/
ISA IDE card in order for it to function properly. The options are: Auto, PCI
Slot1, PCI Slot2, PCI Slot3, PCI Slot4, PCI Slot5, and PCI Slot6.
This feature allows the user to set PCI/PnP configurations for the following
items:
Plug & Play OS
Select Yes to allow the OS to configure Plug & Play devices. (*This is not
required for system boot if you system has an OS that supports Plug &
Play.) Select No to allow AMIBIOS to configure all devices in the system.
Palette Snooping
Select Enabled to inform the PCI devices that an ISA graphics device is
installed in the system in order for the graphics card to function properly.
The options are Enabled and Disabled.
