This section describes configuring the PCI bus system. PCI, or
P
ersonal
C
omputer
I
nterconnect, is a system which allows I/O devices
to operate at speeds nearing the speed the CPU itself uses when
communicating with its own 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.

Resource controlled by
The Award Plug and Play BIOS has the capacity to automatically
configure all of the boot and Plug and Play compatible devices.
However, this capability means absolutely nothing unless you are using
a Plug and Play operating system such as Windows
95. If you set this
field to “manual” choose specific resources by going into each of the
sub menu that follows this field (a sub menu is preceded by a “ ”).
The choice: Auto(ESCD), Manual.
IRQ Resources
When resources are controlled manually, assign each system interrupt
a type, depending on the type of device using the interrupt.
IRQ3/4/5/7/9/10/11/12/14/15 assigned to
Legacy ISA Devices compliant with the original PC AT bus specification, requiring
a specific interrupt ( such as IRQ4 for serial port 1). PCI/ISA PnP Devices
compliant with the Plug and Play standard, whether designed for PCI or ISA bus
architecture.
The Choice: PCI/ISA PnP, Legacy ISA.
DMA Resource
When resources are controlled manually, assign each system DMA
channel a type, depending on the type of device using the DMA channel.
DMA 0/1/3/5/6/7 assigned to
Legacy ISA for devices compliant with the original PC AT bus
specification, PCI/ISA PnP for devices compliant with the Plug and Play
standard whether designed for PCI or ISA bus architecture.
The Choice: Legacy ISA and PCI/ISA PnP.
