Such as SE440BX and such.
What you appear to have are OEM models so these are not so much legacy but pulls from who knows what.
That may be why you and I can't find the docs.
I need help finding info on three Intel legacy motherboards, Intel #s 4000286, 4000434 and 4000472. All three are slot one MB's. I've been to Intel's website but can't seem to find what I'm looking for, jumper settings, useable processors, maximum memory, etc. Anything will be appreciated.
