Hope this helps:
Finally i solved my instability problems with the Abit KT7A-R (Raid not installed).
I upgraded from a Duron 800@866/133MHzFSB to a 1.4/133TB and suddenly Windows locked during booting, my ISA-soundcard (Terratec EWS64XL) had yellow exclamation marks (complete system lockup when enabling the gameport) or my serial-port force feedback wheel lost connection on the com-ports.
The system was stable only up to 800/100 with a 1.4TB.
This is what finally worked for me:
A new BIOS from http://www.centris.free-online.co.uk/
1) I took the user-modified (ACPI on/off option added) ZT version (ZT 103b1) and choosed ACPI off – reinstalled WIN
2) disabled the gameport (Adress 201)
3) but the serial-port still didn’t work with my racing wheel – solution: COM1: data-transfer rate reduced and protocol -> OFF
Now everything’s stable @1.53/133 with most aggressive memory and chipset settings.
