UPDATE:
I was able to update the BIOS to the latest 1012 (using UniFlash 1.40 in DOS, with the appropriate flash file provided by soggi, thank you soggi! 😀)
As expected (thanks for everyone shedding light on this), my Coppermine 650 did not work. I searched my entire collection, and could not find a suitable PIII (fine a 850EB! 😀, which of course could not work), so at the moment I have to revert back to my PII 400 that came pre-installed with the system)
Say, is jump from my PII-400 to a 600+ PIII that noticeable in mid-late 90's FPS games? I mean I tend to play my games at maximum of 800x600 on GeForce 5200, with NO acceleration (I know, that's crazy)
Thanks!
