/*
* One can add a VxD to fix a broken BIOS. This VxD must have
* BIOS_EXT_DEVICE_ID as device ID and must export three services, in that
* order:
*
* GetVersion: must return in eax 0x00000100 for this release and carry
* clear (ie standard version code).
*
* GetHeader: must return in eax the linear address to an installation
* structure, this need not be in BIOS space, but need to have the correct
* values for building BIOS selectors. The structure will be used instead of
* the one found by the scan. Also, the BIOS EXT VxD must use this time to
* initialize. If initialization failed, the value 0 must be return.
*
* CallBIOS: will be called instead of calling the BIOS entry point. The
* stack will be the exact same as if we were calling the BIOS except that
* the return address is a 32-bit ret to BIOS.VxD. Also CS=DS=ES=SS=Flat
* segment. Thus the BIOS_EXT VxD can pop the return address in a local
* variable (this API will never be reentered) and do stack munging before
* calling its internal function or call BIOS even. All registers except
* eax, which is the return value, must be preserved. The high word of eax
* is discarded by BIOS.VxD.
