You might get away with this in DOS/windows, but you won't running FreeBSD. The only other thing, is do these people happen to have recent AMD DXL2/66's, that are really probably 80Mhz 5V die that failed AMD's final test and where packaged as 66Mhz parts. AMD has had to stop manufacturing there 66Mhz parts, but Intel has yet (and probably wont) stop them from makeing the 80Mhz parts. -- Rod Grimes rgrimes@gndrsh.aac.dev.com Accurate Automation Company Custom computers for FreeBSD
