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_VGA_COREBOOT prompt "Include generated option rom that implements legacy VGA BIOS compatibility" default y depends on !VGA_BIOS && MAINBOARD_DO_NATIVE_VGA_INIT bool help Coreboot can initialize the GPU of some mainboards. After initializing the GPU, the information about it can be passed to the payload.

From the wiki: "The bootorder file may be used to configure the boot up order. The file should be ASCII text and contain one line per boot method. The description of each boot method follows an Open Firmware device path format. SeaBIOS will attempt to boot from each item in the file - first line of the file first."
