I did a little benchmarking on my machine, as Stefan requested (are
you on this list?). 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.
Thanks in advance,
Kees Jan Koster
