Could this be Quantum-related instead of VIA-related?
My VIA82C586 is fine with a Western Digital Caviar AC31200 (old EIDE
1.2 GB drive which supports PIO 3 and some slow DMA) which is not UDMA,
however.
The other reason might perhaps be too long of an IDE cable. I don't
know the exact specification, should be something around 30 cm (12 in) for
UDMA?
