I tried to flip that bit manually via ctchips, but - depending on set jumpers on JC1, JC2 and JC4 - the box either (reproducably) freezes, reboots or continues to work normally. The freeze and reboot behavior is highly jumper-config dependent (you'll change some and behavior goes from freeze to …

Hmmm.. Good example is Amiga - that is no more produced as being a pure retro hardware. In past I was playing many first released games (even those from 70's) so this makes me a witness of both hardware and software evolution almost from the beginning. So imho retro means something that was released …

Actually, it's not the same, it's similar. Mine is 603 and Warlord has 402. I've got some strange slot called SmartMedia under DVD-ROM. Also, the modem slot is different and usess another type of connection (I've got 401 model and can compare). Maybe they are using another revision of geforce 2, I …

Still... same - doesnt match! My mobo (if agreed with Your pin countage method) is set to 7-8 at JC1 Yes? Refering to the Manual, it should be then a 486 SX/DX CPU! I don't have but SX/DX - I have installed DX4.... It's simple, you need to add the extra jumper on JC2 pin 13&14 and the extra ones on …
