Using BIOS
PNP/PCI Configurations
These options configure how PnP (Plug and Play) and PCI expansion cards operate in
your system. Both the the ISA and PCI buses on the motherboard use system IRQs
(Interrup ReQuests) and DMAs (Direct Memory Access). You must set up the IRQ and
DMA assignments 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:

Resouces Controlled By (Auto(ESCD)
You should leave this item at the default Auto (ESCD). Under this setting, the system
dynamically allocates resourcesPCI/VGA Palette Snoop (Disabled) 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.
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 USB (Enabled)
Enable or Disable this item when users are to assign IRQ for the USB interface onboard.
