-config PCI_OPTION_ROM_RUN_X86EMU

- help
- If you select this option, the x86emu CPU emulator will be used to
- execute PCI option ROMs.
- When choosing this option, x86emu will pass through all hardware
- accesses to memory and IO devices to the underlying memory and IO
- addresses. While this option prevents option ROMs from doing dirty
- tricks with the CPU (such as installing SMM modules or hypervisors),
- they can still access all devices in the system.
- Choosing x86emu, option ROM execution is slower than native execution
- in real mode, but faster than the full system emulation YABEL
- This is the default choice for non-x86 systems.
