I don't know if any of you have this problem but I have it. Well Windows 2000 wouldn't recognize my Ultra DMA 66 Hard Drive it recognize as PIO I did change to DMA Mode If Available but after resetting I went in Hardware Management and see it as Ultra DMA Mode after few minutes it change back to PIO Mode Only I have no idea was going on so help. I also try the motherboard patch from the cd rom that comes with it but that didn't help. Is there anyway I can make it recognize my Ultra DMA Hard Drive?
