I am having the exact same problem. I could boot fine with my DC-390U3D and an Asus A7V133, but after upgrading to the A7V333 I can no longer boot with the Tekram controller. Yes I have reformatted and reinstalled the OS with the Tekram card.
scalf: Are you able to boot off a Windows 2000 CD, and have it give you the option to start off your hard drive? I can boot off my hard drive if there is a bootable CD in the computer. I have updated the A7V333 BIOS to 1006 (final release 22-Apr-2002, running 1006 Beta 4 before that.) and this doesn't help. If I swap the Tekram card for an Adaptec 2940UW, I can boot the system off the hard drive directly. Bearing in mind I installed Windows 2000 using the Tekram card not the Adaptec...
I've tried to sign up at amdmb, but it's been several days, and they still haven't validated my account registration.
Anybody got any more thoughts on this issue? The Tekram technical support folks have given me really BASIC (think in the context of the animated "REBOOT" TV show.) assistance like, "Make sure your Cheetah X15 is plugged in to CN5." Asus has not responded to any of my emails.
Thanks in advance,
