- The EFI Legacy BIOS Protocol is used to abstract legacy Option ROM usage
- under EFI and Legacy OS boot.
-
- 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.
-
- You most likely should not use this protocol! Find the EFI way to solve the
- problem to make your code portable

- @par Protocol Description:
- Abstracts the traditional BIOS from the rest of EFI. The LegacyBoot()
- member function allows the BDS to support booting a traditional OS.
- EFI thunks drivers that make EFI bindings for BIOS INT services use
- all the other member functions.
-
- @param Int86
- Performs traditional software INT. See the Int86() function description.
-
- @param FarCall86
- Performs a far call into Compatibility16 or traditional OpROM code.
-
- @param CheckPciRom
- Checks if a traditional OpROM exists for this device.
-
- @param InstallPciRom
- Loads a traditional OpROM in traditional OpROM address space.
-
- @param LegacyBoot
- Boots a traditional OS.
-
- @param UpdateKeyboardLedStatus
- Updates BDA to reflect the current EFI keyboard LED status.
-
- @param GetBbsInfo
- Allows an external agent, such as BIOS Setup, to get the BBS data.
-
- @param ShadowAllLegacyOproms
- Causes all legacy OpROMs to be shadowed.
-
- @param PrepareToBootEfi
- Performs all actions prior to boot. Used when booting an EFI-aware OS
- rather than a legacy OS.
-
- @param GetLegacyRegion
- Allows EFI to reserve an area in the 0xE0000 or 0xF0000 block.
-
- @param CopyLegacyRegion
- Allows EFI to copy data to the area specified by GetLegacyRegion.
-
- @param BootUnconventionalDevice
- Allows the user to boot off an unconventional device such as a PARTIES partition.
