Abit KV8 Pro

[Gherault]

I've got bios revision 16, newest as far as I am aware at the time of this post. I have a very odd boot issue where the computer fails to recognize a harddisk the first time, but if you alt-ctrl-del it will boot perfectly well the next, or if you do a softboot or even reset. (hard kills make it do this) I've swapped out all my hardware save CPU (can't afford an extra) and it does the same thing. Tried a fresh HD also. Any ideas? It's too late for a RMA. 🙁

Also: anyone know what HT Tristate is? it's a toggle in the bios that I can't find any reference to anywhere, the two options are Driven and Tristate. *shrug*

Other than that the board is awsome, the pro chipset is a good bit more efficient than the KV8-MAX3 I was replacing.

When you flashed the bios did you clear it right away also? I've seen that where it was reading reminants of the old bios somehow.

The HT Tristate setting probably sets the LDT3SEN bit in the chipset registers:

------------
LDT3SEN: link three-state enable. Read-write. 1=During the LDTSTOP# disconnect sequence, the
link transmitter signals are placed into the high impedance state and the receivers are prepared for the
high impedance mode. For the receivers, this includes cutting power to the receiver differential
amplifiers and ensuring that there are no resultant high-current paths in the circuits. 0=During the
LDTSTOP# disconnect sequence, the link transmitter signals are driven, but in an undefined state,
and the link receiver signals are assumed to be driven. Note: this bit is cleared by PWROK reset but
not by RESET#. AMD recommends that this bit be set high in single-processor systems and be low in
multi-processor systems.

Thank you SOOOOO much on the Tristate Info. 🙂

Oh, and PS: A Snaaaaaaake!
