I haven't had to tangle with problems too often so it's embarassing how much I don't know, or have forgotten
I'm having a related problem. After an upgrade of my graphics drivers a while back some things have changed for the worse, and I've been unable to revert, even by fulling uninstalling all of my ati software, .inf files, registry keys, etc. (all as according to faq from rage3d) and reinstalling the card with the older drivers.
It still seems to get recognized as pci, and system info (98se) reports it as sharing irq 11 with "ACPI IRQ Holder for PCI IRQ Steering". I've tried reinstalling my via 4 in 1's, and later updated them and reinstalled the card, but still the same. Also btw, my adjacent pci slots are empty. VGA is set to AGP in my BIOS as well. Do I simply reassign irq? Sorry to be so thick, suggestions welcome
