'Old PC' emulation ?

Hi Fred, Andy once told me (us) that in the beginning of Minix he got it almost finished, but that there was one weird instability problem. To solve this, he wrote an emulator that completely emulated a PC (I think back in those days that must have been a PC/XT or something like that, he talked about hardware without harddrive, only 2 5,25" disk drives) to figure out what happened. To his disappointment it didn't give him a solution, as the system behaved stable in his emulator. In the end, someone pointed him in the direction of spurious interrupts. In the end that was the cause of the instability. Andy said that the code of his simulator must be around on the internet. Perhaps you can find it and compile a version to run on Windows. Maybe it's even on one of your disks! Besides that, I would like to point out that current releases of Minix are documented to run on Boochs. Bert
