Just disable UDMA in the BIOS (unless you have a fucked-up AMI BIOS which won't let you disable UDMA).

DMA is supposed to work on all chipsets (AFAIK). UDMA is known to be broken on some chipsets (including the Acer Aladdin IV/V). > I checked the archives but they didn't reveal anything useful to me. Search for UDMA or UltraDMA (or variants thereof) in the -hackers and -current archives.
