Chapter 4 - BIOS Setup

PNP/PCI Configurations
This section describes configuring the PCI bus system and PnP (Plug & Play) feature.
PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to
operate at speeds nearing the speed the CPU itself uses when communicating with its
special components. This section covers some very technical items and it is strongly
recommended that only experienced users should make any changes to the default
settings.
Primary Graphic
’
s Adapter
This item specifies which VGA card is your primary graphics adapter. Settings: [PCI
Slot], [AGP].
IRQ Resources Arrange
Press <Enter> and the following sub-menu appears:
IRQ 3/4/5/7/9/10/11/12/14/15
These items specify the bus where the specified IRQ line is used.
The settings determine if BIOS should remove an IRQ from the pool of available
IRQs passed to devices that are configurable by the system BIOS. The available
IRQ pool is determined by reading the ESCD NVRAM. If more IRQs must be removed
from the IRQ pool, the end user can use these settings to reserve the IRQ by
assigning an [Reserved] setting to it.
