Thanks for the informative response. I'm not sure if the BIOS upgrade in
the URL you posted would apply to me. My motherboard is a Tyan Titan III
1468 using an Award BIOS (I think version 4.01; I'd have to reboot to
check). The date on the BIOS I do recall, and that is 12/31/1996.
I've had this motherboard for a few years and have been using IDE w/DMA
with not so much as a hiccup, until 2.1.7someodd (I think .76).
thanks,
