I'm pretty sure the problem is not the disks in my case. I have tried a Seagate ST36531A and a Samsung SW0434A. Both do work without a problem in another motherboard with a different chipset. Here are a few reasons why it can work for you and not some others: Maybe VIA changed something in the chip and didn't change the number of the chip. (On the 596 they only changed the revision number and added 66M DMA if I understand the code correctly.) Maybe the ata driver don't configure all registers and assume the BIOS will do some and the BIOSes do it different. Maybe the motherboard designers screwed up somewhere which make 33M DMA not work on those boards. John -- John Hay -- John.Hay@mikom.csir.co.za > Yeah, I saw those.
