help
Execute PCI/AGP option ROMs if available. This is required to
enable PCI/AGP VGA plugin cards. This option is not exposed
to the user but set by the options PCI_OPTION_ROM_RUN_VM86
, PCI_OPTION_ROM_RUN_X86EMU and PCI_OPTION_ROM_RUN_YABEL.
choice
prompt "Execute PCI Option ROMs"
default PCI_OPTION_ROM_RUN_VM86
help
Execute PCI/AGP option ROMs if available. You can choose to
execute PCI option ROMs natively (32bit x86 system required),
in an emulator (x86emu), or ignore option ROM execution.
config PCI_OPTION_ROM_RUN_X86EMU
bool "x86emu"
select PCI_OPTION_ROM_RUN
help
If you choose this option, the x86 instruction set emulator
x86emu is used to execute 16bit legacy BIOS option ROMs.
x86emu is slow, big and safe. All 16bit x86 code is executed
in an encapsulated environment where it can not break out.
config PCI_OPTION_ROM_RUN_YABEL
bool "YABEL"
select PCI_OPTION_ROM_RUN
help
YABEL: Yet another BIOS Emulation Layer
If you choose this option, the x86 instruction set emulator
x86emu is used to execute 16bit legacy BIOS option ROMs just
like the "x86emu" choice.
The BIOS Emulation code is very different from the "x86emu"
choice however, it is a more complete legacy BIOS implementation
and should be able to execute more Option ROMs than the
"x86emu" choice
YABEL is even slower and bigger than x86emu and just as safe.
All 16bit x86 code is executed in an encapsulated environment
where it can not break out.
config PCI_OPTION_ROM_RUN_VM86
bool "vm86"
select PCI_OPTION_ROM_RUN
depends ARCH_X86
help
If you choose this option, the virtual x86 mode "vm86" is used
to execute 16bit legacy BIOS option ROMs.
vm86 is very small, fast, and probably a little less safe than
x86emu, since it runs option ROMs on the real hardware instead
of an emulator.
config PCI_OPTION_ROM_RUN_NONE
bool "Disabled"
help
Do not execute PCI option ROMs at all.
If you choose this option, VGA plugin cards will not be initialized.

menu "Advanced YABEL Settings"

config YABEL_VIRTMEM_LOCATION
hex "YABEL Virtual Memory Location"
help
Set the location that YABEL uses for "virtual" memory.
YABEL uses its own memory where INT handlers, BIOS Config
Area and Option ROM code is copied to. This is needed to
keep YABEL in its own environment. This memory area will be
overwritten by YABEL, so no necessary data for coreboot
must reside here.
If YABEL_ADVANCED_SETTINGS is not enabled, the code defaults
to 0x1000000 (16 MB).

config HW_MEM_HOLE_SIZEK
hex "HW memory hole size in KB"
depends CPU_AMD_K8
default 0x1000
help
Some chipsets support setting up a "hole" at the top of memory.
It is essentially a hole torn in the physical address space so that
you can fit non-memory resources (e.g. flash) at the top of the 4G
address space. Given that this only happens on machines with lots
of memory, the default 4 MB is a very reasonable value.
