* o The FrobOS code, which instead should either program the virtual chipset
52
* (like the new BIOS code does, matthias offered to implement that), or not
53
* use any VM-specific code (which requires that we correctly implement
54
* "power off on CLI HLT" for SMP VMs, boris offered to implement that)
56
* o The old BIOS code, which will soon be jettisoned
