I have the VIA KT266A chipset. I can't offer much help. I've noticed
that DMA does not work well on CDROM drives for me. Simply disabling DMA
seems to fix any issues. I tried configuring pcibios different ways. I
never did disable it though. Perhaps you should try that. My problem was
with my 802.11b card. It couldn't configure it due to the pci interrupt
routing, otherwise the system was quite functional.
