If you select this option, PCI option ROMs will be executed

If you select this option, the x86emu CPU emulator will be used to
|
|
execute PCI option ROMs.
|
|
|
|
This option 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 native option ROM initialization
|
|
method.
|

This is the default choice for non-x86 systems.

Per default, YABEL only allows option ROMs to access the PCI device

that they are associated with. However, this causes trouble for some

onboard graphics chips whose option ROM needs to reconfigure the

north bridge.

help
|
|
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).
|
|
|
|
When choosing this option, x86emu will pass through all hardware
|
|
accesses to memory and I/O devices to the underlying memory and I/O
|
|
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.
|
|
Enable this option for a good compromise between security and speed.
