-Module Name:\r
-\r
- LegacyBios.h\r
- \r
-Abstract:\r
-\r
- The EFI Legacy BIOS Protocol is used to abstract legacy Option ROM usage\r
- under EFI and Legacy OS boot.\r
-\r
- Note: The names for EFI_IA32_REGISTER_SET elements were picked to follow \r
- well known naming conventions.\r
-\r
- Thunk - A thunk is a transition from one processor mode to another. A Thunk\r
- is a transition from native EFI mode to 16-bit mode. A reverse thunk\r
- would be a transition from 16-bit mode to native EFI mode.\r
-\r
-\r
- Note: Note: Note: Note: Note: Note: Note:\r
-\r
- You most likely should not use this protocol! Find the EFI way to solve the\r
- problem to make your code portable\r
-\r
- Note: Note: Note: Note: Note: Note: Note:\r
-\r
-Revision History\r
-\r
- The EFI Legacy BIOS Protocol is compliant with CSM spec 0.96.\r
