Using BIOS
PNP/PCI Configurations
This section describes configuring the PCI bus system. PCI (Peripheral Component Inter-
connect) is a system, which allows I/O devices to operate at speeds nearing CPU’s when they
communicate with own special components. All the options describes in this section are
important and technical and it is strongly recommended that only experienced users should
make any changes to the default settings.
Reset Configuration Data (Disabled)
When 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(ECSD))
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.
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.
INT Pin1~8 Assignment (Auto)
Identifies the interrupt request (IRQ) line assigned to a device connected to the PCI inter-
face of your system.

Assign IRQ For USB (Enabled)
“Enable” or “Disable” this item when users are to assign IRQ for the USB interface onboard.
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.
