Re: LPX motherboard booted up

Hi Ben !

( you have my email )

I would tend to doubt that an Intel FX chipset board would recognize an AMD
chip, but stranger things happen. Interesting that it supports down to 2.2V
also.

I sure remember AST. Saw Gazzilions of 'em.

Predictably, the board stopped with a post code of D4, when the AMD K6-2
/400 was installed. Only way to work around this would be to install a
hacked BIOS, well beyond any effort I want to put in.

Photo on the way to you, Bob.
