| I'd take F, but I already have two. That Biostar MB8500TTD has an updated BIOS from Jan Steunbrink that allows you to use Cyrix 6x86 4x chips as well as K6-III and 2/3+ chips. I run mine with a K6-III+ at 500 MHz, 2.2 V, 256 MB RAM. |

Yeah, that is what makes it interesting. K6-III-500 on a 430TX.
cvandijk: Yes, I have the BIOS. I don't think Jan ever updated his website with it and many other BIOSes he modified a la carte. |
