This feature is for the operating system that 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 VIA VT8235 chipset), INT#
(means PCI slot IRQ signals) and devices, please refer to the table below:
Signals
PIRQ_0
Assignment
PIRQ_1
Assignment
PIRQ_2
Assignment
PIRQ_3
Assignment
AGP INT A INT B
PCI-1 INT A INT B INT C INT D
PCI-2 INT B INT D INT C INT A
PCI-3 INT B INT A INT D INT C
PCI-4 INT D INT A INT B INT C
PCI-5 INT C INT D INT A INT B
PCI-6 INT D INT B INT C INT A
HPT372 (KD7-RAID) INT A
LAN (KD7/KD7-RAID) INT A
LAN (KD7-G/S/B) INT A
SATA (KD7-G/S) INT A
NOTE:
•
PCI slot 1 shares IRQ signals with AGP slot.
•
PCI slot 2 shares IRQ signals with PCI slot 6, and LAN (KD7-G, KD7-S, KD7-B).
•
PCI slot 3 shares IRQ signals with PCI slot 4, and LAN (KD7/KD7-RAID).
•
PCI slot 5 shares IRQ signals with HPT372 (KD7-RAID), and SATA (KD7-G, KD7-S).
•
If you want to install two PCI cards into those PCI slots that share IRQ with one another at the same
time, you must make sure that your OS and PCI devices’ driver supports the IRQ sharing function.
