Execute PCI/AGP option ROMs if available. This is required to

Execute PCI/AGP option ROMs if available. You can choose to
|
|
execute PCI option ROMs natively (32bit x86 system required),

in an emulator (x86emu), or ignore option ROM execution.

help
|
|
If you choose this option, the x86 instruction set emulator
|
|
x86emu is used to execute 16bit legacy BIOS option ROMs.
|
|
|
|
x86emu is slow, big and safe. All 16bit x86 code is executed
|
|
in an encapsulated environment where it can not break out.

help
|
|
If you choose this option, the virtual x86 mode "vm86" is used
|
|
to execute 16bit legacy BIOS option ROMs.
|
|
|
|
vm86 is very small, fast, and probably a little less safe than
|
|
x86emu, since it runs option ROMs on the real hardware instead
|
|
of an emulator.
