ide dma still appears to be unusable with my VIA chipset board even with SuSE-8.2 (it hangs so solid while starting up KDE that the ATX power switch won't even turn it off -- and then part of the CMOS is changed when I reboot!) This is no big problem for me since I have gotten used to not using DMA on this machine, but I just wondered if there were any VIA chipset users reading this list who had gotten it work.

I have it working (or rather the kernel) with dma for my hard drives, but NOT my dvd or cdrw (they have problems with DMA enabled.

Excellent -- your example gave me the motivation to remove my ISA sound card and give UDMA another shot -- and so far it is working like a champ (but I think I will give my disks a good long torture test before putting down any money for a new PCI sound card.) Thanks.
