20 mainmenu "Coreboot Configuration"
27 This allows you to select certain advanced configuration options.
29 Warning: Only enable this option if you really know what you are
30 doing! You have been warned!
33 string "Local version string"
35 Append an extra string to the end of the coreboot version.
37 This can be useful if, for instance, you want to append the
38 respective board's hostname or some other identifying string to
39 the coreboot version number, so that you can easily distinguish
40 boot logs of different boards from each other.
43 string "CBFS prefix to use"
46 Select the prefix to all files put into the image. It's "fallback"
47 by default, "normal" is a common alternative.
53 This option allows you to select the compiler used for building
58 config COMPILER_LLVM_CLANG

80 Enables the use of ccache for faster builds.
81 Requires ccache in path.
83 config USE_OPTION_TABLE
84 bool "Use CMOS for configuration values"
87 Enable this option if coreboot shall read options from the "CMOS"
88 NVRAM instead of using hard coded values.

356 Select this option if you want to create an "empty" coreboot
357 ROM image for a certain mainboard, i.e. a coreboot ROM image
358 which does not yet contain a payload.
360 For such an image to be useful, you have to use 'cbfstool'
361 to add a payload to the ROM image later.
364 bool "An ELF executable payload"
366 Select this option if you have a payload image (an ELF file)
367 which coreboot should run as soon as the basic hardware
368 initialization is completed.
370 You will be able to specify the location and file name of the

426 the "0x" prefix) and 3230 specifies the PCI device ID of the
427 video card (also in hex, without "0x" prefix).

469 prompt "VESA framebuffer video mode"
472 depends on BOOTSPLASH
474 This option sets the resolution used for the coreboot framebuffer and
475 bootsplash screen. Set to 0x117 for 1024x768x16. A diligent soul will
476 some day make this a "choice".
478 config COREBOOT_KEEP_FRAMEBUFFER
479 prompt "Keep VESA framebuffer"
481 depends on BOOTSPLASH
483 This option keeps the framebuffer mode set after coreboot finishes
484 execution. If this option is enabled, coreboot will pass a
485 framebuffer entry in its coreboot table and the payload will need a
486 framebuffer driver. If this option is disabled, coreboot will switch
487 back to text mode before handing control to a payload.
