I updated painfully BIOS on my Biostar M6TZA and I put modified Slocket1 with P3 into it and it works, I never thought it's possible but now it works. At first it was freezing in BIOS (still freezes in one only option to set FSB), I replaced with P3 800MHz 133FSB what gave 600E MHz, it started, Win98 worked, I decided to put back P3 800MHz 100FSB (a bit crushed edge but works) and works great! I used tutorial that said to bridge reset and VSS line plus get rid of one pin on the very edge. I'm glad it does and this is adapter I used
