-         You can choose to execute PCI option ROMs natively (32bit x86 system
-         required) or in an emulator (x86emu or YABEL).
+         If you select this option, PCI option ROMs will be executed
+         natively on the CPU in real mode. No CPU emulation is involved,
+         so this is the fastest, but also the least secure option.

+         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.
