This is the same VIA Southbridge chip as was used in the Socket 7 motherboards. On those motherboards, I have needed to change BIOS settings and shuffle cards between PCI slots to prevent shared interrupts on a Symbios 53C875 card and on the first IDE controller for proper operation in both FreeBSD and Win NT 4. Other PCI cards and devices seem to do okay sharing interrupts. I never resolved whether this was a chipset problem or card problem, but can vouch for its existence in some circumstances.
