-config CONSOLE_VGA_MULTI
+ 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.
