Typically, this era of P54 boards would not support more than a 166 because the regulator topped out near 15W and officially, P200 and P200MMX were a little over that. I am not seeing the value of trying to troubleshoot the board with a P55 still as it's probably pushing over 15W when used at 3.3V …

Excuse a piece of information, what CPU do you currently have on the Motherboard? Seeing the images (photo of the link), the Pentium MMX CPU doesn't seem supported, I see only one mosfet, and if you don't have two, you can't put a Dual Voltage CPU, the only solution is the Pentium Overdrive MMX, …

Did you set the jumpers back to 133MHz? Oh and this board, even though "P55C" is mentioned in the manual, does NOT support MMX CPUs or any other split-voltage CPUs. I will adjust the page accordingly. I did, now the bios always freeze at that screen, i already found a decently cheap motherboard for …

YES! the flashing fixed the millennium 2 ATTENTION FOR PEOPLE FROM THE FUTURE CHECKING THIS Apparently the progbios utility has a hidden command to force the flashing, it's -k, so if you can't normally flash the gpu use the command like this progbios -i 838-20.bin -k 838-20.bin is an example, you …

Were you not able to simply go into Safe Mode in Windows 95 with the original card and set the resolution to 640x480 16 colours? Or were you not even seeing the F8 menu? Also remove any graphics tools you may have been playing around with from config.sys &/or autoexec.bat. Somehow i can't even see …

What resolution were you running when you changed the setting? Do you have a newer monitor that possibly could handle the resoltion/refresh rate combo? If so, hook that one up, change setting back and see if it works again with the original monitor. I don't have a monitor able to take weird …
