ACPI poweroff with seabios works just fine. If APM support in seabios uses something else it should be switched to use the same hardware ports ACPI uses for poweroff (some piix4 pm device register I think) instead of the debug ports which where never meant to be used that way. Does bochs bios run on recent qemu versions in the first place? cheers, Gerd
