I haven't had the time to do the bytebench yet. Maybe later. Machine: Exp8661 mainboard, 512kb PB cache, 32Mb EDO, AMD 5k86-P100 @ 100MHz (overclocking doesn't work :). Could someone shed some light on the 'bad MHz' messages below? It worries me a little, because I had some touble before. Unix worked like it always has: sweet as honey, and MS-DOS kept tripping over its feet: random hangs and crashes, missed sequences on the soundcard, etc. Both Unix and MS-DOS work, altough MS-DOS still feels kind'a fragile.
