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.
Init Display First
This item specifies which VGA card is your primary graphics adapter. Setting options:
[PCI Slot],
[PCI Ex].
PCI Slot1/2 IRQ
These items specify the IRQ line for each PCI slot. Setting options: [3], [4], [5], [7], [9],
[10], [11], [12], [14], [15], [Auto]. Selecting [Auto] allows BIOS to automatically determine
the IRQ line for each PCI slot.
** PCI Express relative items **
Maximum Payload size
It allows you to set the maximum TLP payload size for the PCI Express devices. Setting
options: [128 bytes], [256 bytes], [512 bytes], [1024 bytes], [2048 bytes], [4096 bytes].
