This specifies how long SeaBIOS will wait for the keyboard controller to become ready before giving up. config SEABIOS_THREAD_OPTIONROMS prompt "Hardware init during option ROM execution" default n bool help Allow hardware init to run in parallel with optionrom execution. This can reduce boot time, but can cause some timing variations during option ROM code execution. It is not known if all option ROMs will behave properly with this option. config SEABIOS_MALLOC_UPPERMEMORY bool default y help Use the "Upper Memory Block" area (0xc0000-0xf0000) for internal "low memory" allocations. If this is not selected, the memory is instead allocated from the "9-segment" (0x90000-0xa0000). This is not typically needed, but may be required on some platforms to allow USB and SATA buffers to be written correctly by the hardware. In general, if this is desired, the option will be set to 'N' by the chipset Kconfig. config SEABIOS_VGA_COREBOOT prompt "Include generated option rom that implements legacy VGA BIOS compatibility" default n depends on !VGA_BIOS && (MAINBOARD_DO_NATIVE_VGA_INIT || MAINBOARD_HAS_NATIVE_VGA_INIT_TEXTMODECFG) bool help Coreboot can initialize the GPU of some mainboards. After initializing the GPU, the information about it can be passed to the payload. Provide an option rom that implements this legacy VGA BIOS compatibility requirement. config PAYLOAD_CONFIGFILE string "SeaBIOS config file" default "" help This option allows a platform to set Kconfig options for a basic SeaBIOS payload. In general, if the option is used, the default would be "$(top)/src/mainboard/$(MAINBOARDDIR)/config_seabios" config PAYLOAD_FILE default "payloads/external/SeaBIOS/seabios/out/bios.bin.elf" config PAYLOAD_VGABIOS_FILE string depends on SEABIOS_VGA_COREBOOT default "payloads/external/SeaBIOS/seabios/out/vgabios.bin" endif
