Description:

QEMU gives an error on boot because of OS2LVM.DMD. This is patched version of OS2LVM.DMD. It seems that any hardware CPU now executes the SGDT instruction as 32-bit, despite of 16-bit or 32-bit code segment. But QEMU in 16-bit code works as it written in the Intel documentation and such kindness cause a trap in OS2LVM. Patched version here, I found 3 sgdt in 16-bit code (prefix 66h added).
