Hi, I couldn't find Cyrix 5x86-100 cpu jumper settings for M912 V1.7 board. Which settings would work? I have two of these boards one with AMI one with award bios.

Mind that M912 ver. 1.4 is a slightly different from ver. 1.7 (and subsequent newer update board revisions with fake cache "chips"). I don't know which board revision you have, but TRW link posted by Nexxen is for manual for M912 ver. 1.7 motherboard and it has some extra CPU settings jumper (JP34 and JP35 - these are missing on ver. 1.4 board). If I recall correctly JP35 is related to 4 V CPU setting, which is a Cyrix thing.

MY both mobo is 1.7. Anyway, I downloaded dual bios file for 1.7 from vogonsdriver library.

https://vogonsdrivers.com/getfile.php?fileid= … 675&menustate=0

Flashed it, ami bios was not stable and crashed thorough startup and benchs. But with Award bios, it seems stable and with max optimization of timings, it gives 316.7 sysinfo, 13.3 Quake score with cyrix boost by 5x86 command.

Adding photos and 5x86 parameters batch file that runs stable.

Probably cause of CHips&Tech VLBus graphic card. This card outperforms most of the cards out there. I'll test it in detail. Found it recently.
