I've been using my A7V133 with Win2K for about a week. I did some rigorous tests, using SETI@Home and 3DMark2001 for about a days worth of time. Still stable after I shut them down and started running regular apps and surfing the internet.
I installed and configured Win2K in this order:
1) Install right off with the SCSI controller (my HD is ATA100, so even though I was on the Primary IDE slot, I did this anyways).
2) Afterwards, VIA 4-in-1 v4.31 drivers came next.
3) Graphics drivers
4) If you're not using an SB sound card, install those drivers
5) Win2K Service Pack 2
6) DirectX 8.0a
7) Use Microsoft's Windows Update website and updates critical, security updates. (Windows 2000 Compatibility update, most likely.)
That's enough for now...you haven't even bought the motherboard yet...LoL
