Not that hot for DOS users ...

IIRC Jayson Burgon whined about some "PIT-BUG" in both BOCHS and QEMU some (long) time ago

This one apparently broke it: it crashes just before booting should start, a deadloop of TripleFault's in WRMSR instruction

2.4 doesn't have the WRMSR bug and still works for me. Also, both 2.4 and 2.4.2 have one useless missing import.
