Might help but I have my doubts (do the memory slots while you're at it)
You never really said if this was a recent purchase or an old board you've had working in the past.
We're not even sure if it's a retail or OEM board (at the very least, both Gateway & Mitsubishi/Apricot had systems using it) or what BIOS revision you're currently running. Probably still worth another shot at a 'back to basics' methodical test plan - do a complete system CMOS reset / yank the battery for a few hours, then get the earliest stepping 66Mhz PII 233-300 you have with single sticks of 66MHz SDRAM / 60ns EDO memory (unbuffered ECC / non-ECC) 128MB or less, a basic PCI & AGP card and as many PS/2 keyboards as you have and just walk thru each combination and note the results (not forgetting to test each memory bank from 0 to 3 separately with each combo).
As a last resort, maybe try a forced BIOS recovery from floppy using the J7E1 jumper again - you have an available choice of Gateway P09, Intel P10 & Mitsubishi/Apricot P10 (think they're just using the Intel retail one)
Any or all of the above may work, may not - depends on how much effort you want to put in to solve, or at least better identify, the problem.
