Plug & Play O/S
This lets BIOS configure all devices in the system or lets the OS configure PnP devices not required for boot if your
system has a Plug and Play OS.

This item sets value in units of PCI clocks for PCI device latency timer register. Options are: 32, 64, 96, 128, 160,
192, 224, 248.
Allocate IRQ to PCI VGA
This assigns IRQ to PCI VGA card if card requests IRQ or doesn't assign IRQ to PCI VGA card even if card
requests an IRQ.
Palette Snooping
This informs the PCI devices that an ISA graphics device is installed in the system so the card will function correctly.
PCI IDE BusMaster
This uses PCI busmastering for BIOS reading / writing to IDE devices.
OffBoard PCI/ISA IDE Card
Some PCI IDE cards may require this to be set to the PCI slot number that is holiding the card.
AUTO
: Works for
most PCI IDE cards.
IRQ#

.
Reserved Memory Size
