- Do not execute PCI/AGP option ROMs.

+ 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

+ YABEL consists of two parts: It uses x86emu for the CPU emulation and
+ additionally provides a PC system emulation that filters bad device and
+ memory access (such as PCI config space access to other devices than the
+ initialized one).
+ This option best prevents option ROMs from doing dirty tricks with the
+ system (such as installing SMM modules or hypervisors), but it is also
+ significantly slower than the other option ROM initialization methods.
