faster, but also lacks flexibility in setting modes.
If unsure, say N.

When using a SeaBIOS payload it runs all option ROMs with much
more complete BIOS interrupt services available than coreboot,
which some option ROMs require in order to function correctly.
If unsure, say N when using SeaBIOS as payload, Y otherwise.

help
Always load option ROMs if any are found. The decision to run
the ROM is still determined at runtime, but the distinction
between loading and not running comes into play for CHROMEOS.
An example where this is required is that VBT (Video BIOS Tables)
are needed for the kernel's display driver to know how a piece of
hardware is configured to be used.

Load Option ROMs stored on PCI/PCIe/AGP VGA devices in coreboot.
If disabled, only Option ROMs stored in CBFS will be executed by
coreboot. If you are concerned about security, you might want to
disable this option, but it might leave your system in a state of
degraded functionality.

help
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.
(only works on x86/x64 systems)
config PCI_OPTION_ROM_RUN_YABEL
prompt "Secure mode"
bool
depends on !GEODE_VSA
help
If you select this option, the x86emu CPU emulator will be used to
execute PCI Option ROMs.
This option prevents Option ROMs from doing dirty tricks with the
system (such as installing SMM modules or hypervisors), but it is
also significantly slower than the native Option ROM initialization
method.
This is the default choice for non-x86 systems.

config YABEL_PCI_ACCESS_OTHER_DEVICES
prompt "Allow Option ROMs to access other devices"
bool
depends on PCI_OPTION_ROM_RUN_YABEL
help
Per default, YABEL only allows Option ROMs to access the PCI device
that they are associated with. However, this causes trouble for some
onboard graphics chips whose Option ROM needs to reconfigure the
north bridge.
config YABEL_PCI_FAKE_WRITING_OTHER_DEVICES_CONFIG
prompt "Fake success on writing other device's config space"
bool
depends on YABEL_PCI_ACCESS_OTHER_DEVICES
help
By default, YABEL aborts when the Option ROM tries to write to other
devices' config spaces. With this option enabled, the write doesn't
follow through, but the Option ROM is allowed to go on.
This can create issues such as hanging Option ROMs (if it depends on
that other register changing to the written value), so test for
impact before using this option.
config YABEL_VIRTMEM_LOCATION
prompt "Location of YABEL's virtual memory"
hex
depends on PCI_OPTION_ROM_RUN_YABEL
default 0x1000000
help
YABEL requires 1MB memory for its CPU emulation. This memory is
normally located at 16MB.
config YABEL_DIRECTHW
prompt "Direct hardware access"
bool
depends on PCI_OPTION_ROM_RUN_YABEL && ARCH_X86
help
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.

your VGA BIOS to your video card.

In the above example 1106 is the PCI vendor ID (in hex, but without
the "0x" prefix) and 3230 specifies the PCI device ID of the
video card (also in hex, without "0x" prefix).
Under GNU/Linux you can run `lspci -nn` to list the IDs of your PCI devices.

prompt "Keep VESA framebuffer"
bool
depends on HAVE_VGA_TEXT_FRAMEBUFFER && (HAVE_VBE_LINEAR_FRAMEBUFFER || HAVE_LINEAR_FRAMEBUFFER)
help
This option keeps the framebuffer mode set after coreboot finishes
execution. If this option is enabled, coreboot will pass a
framebuffer entry in its coreboot table and the payload will need a
framebuffer driver. If this option is disabled, coreboot will switch
back to text mode before handing control to a payload.
config BOOTSPLASH
prompt "Show graphical bootsplash"
bool
depends on FRAMEBUFFER_SET_VESA_MODE
help
This option shows a graphical bootsplash screen. The graphics are
loaded from the CBFS file bootsplash.jpg.
You can either specify the location and file name of the
image in the 'General' section or add it manually to CBFS, using,
for example, cbfstool.
