-Module Name:
-
- LegacyBiosThunk.h
-
-Abstract:
-
- The EFI Legacy BIOS Thunk Protocol is used to abstract Thunk16 call.
-
- Note: The names for EFI_IA32_REGISTER_SET elements were picked to follow
- well known naming conventions.
-
- Thunk - A thunk is a transition from one processor mode to another. A Thunk
- is a transition from native EFI mode to 16-bit mode. A reverse thunk
- would be a transition from 16-bit mode to native EFI mode.
-
-
- Note: Note: Note: Note: Note: Note: Note:
-
- You most likely should not use this protocol! Find the EFI way to solve the
- problem to make your code portable

- Arguments:
- This - Protocol instance pointer.
- BiosInt - Processor interrupt vector to invoke
- Reg - Register contexted passed into (and returned) from thunk to
- 16-bit mode
-
- Returns:
- FALSE - Thunk completed, and there were no BIOS errors in the target code.
- See Regs for status.
- TRUE - There was a BIOS erro in the target code.
