You must be familiar with the PCI interrupt distribution mechanism to adjust
this setting. This feature is for the operating system which will record and fix
the PCI configuration status, if you want to change it.
For the relations between the hardware layout of PIRQ (the signals from the
PIIX4 chipset), INT# (means PCI slot IRQ signals) and devices, please refer to
the table below:
Signals PCI slot 1
AGP slot
PCI slot 2 PCI slot 3 PCI slot 4
PCI slot 5
PIRQ_1 INT A INT D INT C INT B
PIRQ_2 INT B INT A INT D INT C
PIRQ_3 INT C INT B INT A INT D
PIRQ_4 INT D INT C INT B INT A
! USB used PIRQD.
! Each PCI slot has four INT#s (INT A~INT D), and the AGP slot has two
INT# (INTA and INT B).
(7) Load Setup Defaults
Setup defaults are the settings that allow your system to operate at its highest
performance. When you choose this option, the following message is displayed:
“Load Setup Defaults (Y/N)? N”
If you want to use BIOS Setup default values, press “Y”, than <Enter> to
complete the loading of the settings for best performance.
You should first load the best settings, than enter the CPU Soft Menu to set up
CPU parameters, otherwise the BIOS will replace set parameters by default
parameters.
