Thanks, I will give that a try.

Yes, that seems to be the case. I just checked the Epox Web site and
the BIOS revision of 04/17/2001 for the 8KTA has the following bullet
point:
* Fixed VIA KT133/A/E + 686B issue copying large sized files on
* E/IDE devices with a SB Live sound card installed.
No further mention of the issue is made for later BIOS revisions.
For the software I referred to above, I was referring to Windows
software that includes fixes for the OS drivers. They call it VIA
Apollo 4-in-1 (a.k.a. VIA ServicePack). I am not really up on Windows
behavior but my impression was that this software was necessary to
enable UDMA.
