but I can see only one jumper settings JP5 , and on PCB you have all informations you need.
Regarding max memory I believe it will accept all kond of FPM modules 😀

JP2 and JP3 are most likely Clear CMOS and BIOS flashing en./dis.

Given that there only is a 33.00 MHz crystal, it seems CPU speed is locked to 66 MHz.

thx, CPU did not come with the motherboard, plan to use it for testing - but might need a 66MHz one if indeed locked to 66MHz

JP1 in top left corner I assume is linked to battery...

Hope you're ready for some craptastic Pentium performance. If you're lucky it might even support 64-bit memory! PCI is bridged to the VL-bus. Even though the board doesn't have the VLB slot soldered in, you still get to enjoy the benefits of sub-par PCI bandwidth.

BTW, I think at least in the early versions of P66 it required more than 5V. Something like 5.15V or more. You might want to make sure your board can actually drive a P66...a lot of boards back then weren't reliable at 66MHz.

Just ensure that your power supply is running 5V on the high. IIRC, the Batman's Revenge board mentions 5.27 V.

Hi. Dear topic starter,
Did you manage to read the BIOS content? Can you post it there ?
It is INTEL P28F001BX-T
Best regards.
