Using BIOS
PNP/PCI Configurations
These options configure how PnP (Plug and Play) and PCI expansion cards operate in your
system. Both the ISA and PCI buses on the motherboard use system IRQs (Interrupt
ReQuests) and DMAs (Direct Memory Access). You must set up the IRQ and DMA assign-
ments correctly through the PnP/PCI Configurations Setup utility for the motherboard to
work properly. Selecting PnP/PCI Configurations on the main program screen displays this
menu:

Reset Configuration Data (Disabled)
If you enable this item and restart the system, any Plug and Play configuration data stored
in the BIOS Setup is cleared from memory.
Resources Controlled By (Auto(ESCD))
You should leave this item at the default Auto(ESCD). Under this setting, the system
dynamically allocates resources to Plug and Play devices as they are required.
If you cannot get a legacy ISA (Industry Standard Architecture) expansion card to work
properly, you might be able to solve the problem by changing this item to Manual, and then
opening up the IRQ Resources submenu.
In the IRQ Resources submenu, if you assign an IRQ to Legacy ISA, then that Interrupt
Request Line is reserved for a legacy ISA expansion card. Press <Esc> to close the IRQ
Resources submenu.
PNP OS Installed (No)
Setting this option to “Yes” allows the PnP OS (instead of BIOS) to assign the system
resources such as IRQ and I/O address to the ISA PnP device.
PCI/VGA Palette Snoop (Disabled)
This item is designed to overcome problems that can be caused by some non-standard VGA
cards. This board includes a built-in VGA system that does not require palette snooping so
you must leave this item disabled.
Assign IRQ For VGA/USB (Enabled)
Names the interrupt request (IRQ) line assigned to the VGA/USB (if any) on your system.
Activity of the selected IRQ always awakens the system.
