|
|
* 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.
