I recently got my hands on a second PVI-486SP3 board. Both this and my existing one are 1.22 revisions and besides different south bridge revisions seems to be identical.
However, I can't get the new board to post. Initially I didn't get any error beeps but that was due to a non-working pc speaker.
The board came with RAM and a AMD DX4 but I have also tried using CPU and RAM from my working setup and aligned all jumpers to no success.
After replacing the beeper I get continuous high beeps. There is no sticker on the Winbond chip on the new board but I can only assume that this also uses an Award bios. The only pattern that seems to match is the CPU overheating error. I found that a little implausible as the CPU both has a fan and works flawlessly with my old board.
I only get beeper errors when a cpu is socketed. Nothing if CPU, RAM and graphics are removed or just RAM and graphics are present.
Does anyone have an idea whether this may be caused by a defective sensor on the motherboard or whether this error might be something else entirely? Would it be worth trying to swap the bios chip as well?
