/*
* 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. */
