Q: How are the IRQ resources shared on the KA7-100 and KT7-RAID?
A: The AGP slot and PCI-1 share an IRQ, as do PCI-2 and PCI-3. PCI-4 and PCI-6 share an IRQ, and PCI-5 shares an IRQ with the HPT370 IDE controller.
Manually assigning the IRQs is possible in the "PnP/PCI configuration" page of the BIOS as follows:
PIRQ_0 is for AGP and PCI-1
PIRQ_1 is for PCI-2 and PCI-3
PIRQ_2 is for PCI-5 and HPT370
PIRQ_3 is for PCI-4, PCI-6, and USB
