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.
