21 config VGA_BRIDGE_SETUP
22 bool "Setup bridges on path to VGA adapter"
25 Allow bridges to set up legacy decoding ranges for VGA. Don't disable
26 this unless you're sure you don't want the briges setup for VGA.
28 # TODO: Explain differences (if any) for onboard cards.
30 bool "Run VGA option ROMs"
33 Execute VGA option ROMs, if found. This is required to enable
34 PCI/AGP/PCI-E video cards.
37 bool "Run non-VGA option ROMs"
40 Execute non-VGA PCI option ROMs, if found.
42 Examples include IDE/SATA controller option ROMs and option ROMs
43 for network cards (NICs).
46 prompt "Option ROM execution type"

49 depends on PCI_ROM_RUN || VGA_ROM_RUN
51 config PCI_OPTION_ROM_RUN_REALMODE
56 If you select this option, PCI option ROMs will be executed
57 natively on the CPU in real mode. No CPU emulation is involved,
58 so this is the fastest, but also the least secure option.
59 (only works on x86/x64 systems)
61 config PCI_OPTION_ROM_RUN_YABEL
65 If you select this option, the x86emu CPU emulator will be used to
66 execute PCI option ROMs.
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
73 This is the default choice for non-x86 systems.
77 config YABEL_PCI_ACCESS_OTHER_DEVICES
78 prompt "Allow option ROMs to access other devices"
80 depends on PCI_OPTION_ROM_RUN_YABEL
82 Per default, YABEL only allows option ROMs to access the PCI device
83 that they are associated with. However, this causes trouble for some
84 onboard graphics chips whose option ROM needs to reconfigure the
87 config YABEL_VIRTMEM_LOCATION
88 prompt "Location of YABEL's virtual memory"
90 depends on PCI_OPTION_ROM_RUN_YABEL && EXPERT
93 YABEL requires 1MB memory for its CPU emulation. This memory is
94 normally located at 16MB.
96 config YABEL_VIRTMEM_LOCATION
98 depends on PCI_OPTION_ROM_RUN_YABEL && !EXPERT
101 config YABEL_DIRECTHW
102 prompt "Direct hardware access"
104 depends on PCI_OPTION_ROM_RUN_YABEL
106 YABEL consists of two parts: It uses x86emu for the CPU emulation and
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).
111 When choosing this option, x86emu will pass through all hardware
112 accesses to memory and I/O devices to the underlying memory and I/O
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.
