68 This option prevents option ROMs from doing dirty tricks with the
69 system (such as installing SMM modules or hypervisors), but it is
70 also significantly slower than the native option ROM initialization
71 method.

Stefan Reinauerd650e992010-02-22 04:33:13 +0000[diff] [blame]106 YABEL consists of two parts: It uses x86emu for the CPU emulation and
Uwe Hermann548dbe72010-02-22 16:41:49 +0000[diff] [blame]107 additionally provides a PC system emulation that filters bad device
108 and memory access (such as PCI config space access to other devices
109 than the initialized one).

Stefan Reinauerd650e992010-02-22 04:33:13 +0000[diff] [blame]113 addresses. While this option prevents option ROMs from doing dirty
114 tricks with the CPU (such as installing SMM modules or hypervisors),
115 they can still access all devices in the system.
116 Enable this option for a good compromise between security and speed.
