Anyways, yes -5V requirement sounds odd, but he's claiming he's run into this problem even with i815E boards. I'm gonna humour him and locate a -5V PSU. I have a friend whose father passed away and he had some older P2, Slot A(!) and other old machines around that I didn't claim but the PSUs might have the -5V who knows.
The board is supposed to support 800mhz. I have a P3 800mhz Slot 1 100mhz FSB so I tried that and it still wouldn't post or even get the CPU warm.
Wow, nice, if it's really got its own VRM, and not just voltage clamp jumpers to control the mobo's VRM, it's probably a Powerleap adapter - I don't know of any other models with onboard VRM at least - and one of those is probably worth more than the mobo. If you got it free of additional charge so to speak, you might have done a good deal even if the mobo is broken 😀
Well, if it doesn't cost you anything, it won't hurt to give it a try. But still, yeah, sounds very odd. I'm assuming you've already done the basic stuff, like double checking that you haven't forgotten anything, disconnected and reconnected everything, checked that all standoffs are in the right places and not shorting out something on the board if it's mounted in a case, tried with other DIMMs or moving around the existing one(s), tried another graphics card, etc, etc.
My MS-6119 accepts anything PII and PIII at 66 or 100MHz FSB I throw at it, the CPU:s ignores the multiplier setting from the mobo. The only oddity is a Tualeron 1,4GHz, which reports 1368 MHz or something like that at POST. CPU-z then reports 1400 MHz, or something very close to it. But probably not a bad idea to troubleshoot with something officially supported anyways 😀
