Well, that's what *I'm* here for....

Ummmm... Guys? Running MSD and/or Norton SysInfo will probably be
impossible for the end of all time.. the reason behind this is that Norton
SysInfo messes with a few hardware interrupts and/or ports that change
system timings so that it can get accurate benchmarks. (In fact, in the
case of Norton Sysinfo, I beleive it sets the PIC timers to what FreeBSD
uses for it's profiler, although I couldn't swear on it.)
Those two programs are _VERY_ mean to your OS. They will causes crashes
due to mangled IRQs on just about anything.. for example, try running
SysInfo from a DOS shell given by a MOD/S3M player or just about any other
program that messes with even the _slightest_ system resources that deal
with IRQs or timers. (shudder)
