Module Name:
LegacyBiosPlatform.h
Abstract:
The EFI Legacy BIOS Patform Protocol is used to mate a Legacy16
implementation with this EFI code. The EFI driver that produces
the Legacy BIOS protocol is generic and consumes this protocol.
A driver that matches the Legacy16 produces this protocol
Revision History
The EFI Legacy BIOS Platform Protocol is compliant with CSM spec 0.96.
