I've never owned a DX4/100 and don't ever really plan to, I'm just wondering if the motherboards require 60ns memory or will live happily with the 70ns stuff. Jordan P.S. The Pentiums are cheap enough now that I just can't see investing in 486 technology unless it's for a router or something. > > So if external clock is changed to 25MHz, it's effectively > working with 75MHz internal clock instead of ~100MHz it's > supposed to. > > (I used to have a AMD Am5x86-P75-S 133MHz part overclocked to > 160MHz (ie. 4x33MHz -> 4x40MHz) which I used to run FreeBSD on > but now I've got a P100 for BSD and that machine runs Windows95 > without any problems after I dropped the ISA bus clock down from > 13.33MHz to 10MHz so GUS could keep up.) > > > -- > Bror 'Count' Heinola % count@key.hole.fi % http://pobox.com/~count/ > Pengerkatu 13b A5 % IRC: Count NIC: BH271 % > FI-00530 HELSINKI % Work: bror@sms.fi % Roads?
