The motherboard I'm talking about is the chaintech 6btm btw. Lovely board, most support coppermines, 4xPCI 3xISA and 4 memory slots

I have two of those with 440BX chipset..

A abit BE6
and a asus P3B_F vlagship motherboard (was the best of his time)

Sure BX, no contest there. P3B-F gets my vote, had one for many many years, great mb. Just change the caps in it to new ones and it should be good to go.
