No. It can support 100MHz, but I don't know of any processors which require it. > I've noticed several m/b manufacturers announcing that their m/bs > for the original K6's will run K6-2s with just a BIOS u/g.

I don't see why. Anyway, it works, and I don't even have enough information to be sure that it's not working correctly. The times shown above were compiling on a big, old SCSI drive which is definitely the slowest of the disks on my system (the others are all fast IDE :-). > Have you'd looked at http://www.amd.com ?
