10164,jumping to the BIOS power-on reset vector causes a CPU loop instead of a reboot,Greg A. Woods,,"Apparently it should be possible to reboot a PC by jumping to the BIOS ""power on restart"" vector.

I.e. ""ljmp $0xf000, $0xfff0"", with the CPU in real mode, perhaps after clearing the warm-boot flag in 0040h:0072h.

This works fine on real PCs, including recent HP laptops, etc.

However with VirtualBox since at least 4.0.4, and up to and including 4.1.8, this just puts the VM into an endless loop chewing CPU cycles.",defect,closed,other,VirtualBox 4.1.8,wontfix,"bios,reboot,hang",,other,Mac OS X
