PCI Latency Timer

Set this value to allow the PCI Latency Timer to be adjusted. This option sets the latency
of all PCI devices on the PCI bus. The Optimal and Fail-Safe default setting is 64.
Option Description
32 This option sets the PCI latency to 32 PCI clock cycles.
64 This option sets the PCI latency to 64 PCI clock cycles. This is the default setting.
96 This option sets the PCI latency to 96 PCI clock cycles.
128 This option sets the PCI latency to 128 PCI clock cycles.
160 This option sets the PCI latency to 160 PCI clock cycles.
192 This option sets the PCI latency to 192 PCI clock cycles.
224 This option sets the PCI latency to 224 PCI clock cycles.
248 This option sets the PCI latency to 248 PCI clock cycles.

Allocate IRQ to VGA

Set this value to allow or restrict the system from giving the VGA adapter card an
interrupt address. The Optimal and Fail-Safe default setting is Yes.
Option Description
Yes Set this value to allow the allocation of an IRQ to a VGA adapter card that uses the PCI local bus.
This is the default setting.
No Set this value to prevent the allocation of an IRQ to a VGA adapter card that uses the PCI local bus.

Palette Snooping

Set this value to allow the system to modify the Palette Snooping settings. The Optimal
and Fail-Safe default setting is Disabled.
Option Description
Disabled This is the default setting and should not be changed unless the VGA card manufacturer requires
Palette Snooping to be Enabled.
Enabled This setting informs the PCI devices that an ISA based Graphics device is installed in the system. It
does this so the ISA based Graphics card will function correctly. This does not necessarily indicate a
physical ISA adapter card. The graphics chipset can be mounted on a PCI card. Always check with
your adapter card's manuals first, before modifying the default settings in the BIOS.
