	bool "Prompt for development and/or incomplete code/mainboards"
	help
	  Enable this option if you want to test development features or
	  incomplete/unsupported mainboards.

	  We do not make any guarantees about anything that is marked
	  as EXPERIMENTAL! You have been warned!

config EXPERT
	bool "Expert mode"
	help
	  This allows you to select certain advanced configuration options.
	  It is mainly intended for LinuxBIOS developers.

	  Warning: Only enable this option if you really know what you're
	  doing! You have been warned!

config LOCALVERSION
	string "Local version - append to LinuxBIOS release"
	help
	  Append an extra string to the end of the LinuxBIOS version.

config BEEPS

config PAYLOAD_PREPARSE_ELF
	bool "Pre-parse ELF file and convert ELF segments to LAR entries"
	depends EXPERT
	default n
	help
	  Until now, LinuxBIOS has used ELF for the payload. There are many
	  problems with this, not least being the inefficiency -- the ELF has
	  to be decompressed to memory and then the segments have to be
	  copied. Plus, lar can't see the segments in the ELF -- to see all
	  segments, you have to extract the ELF and run readelf on it.

	  There are problems with collisions of the decompressed ELF
	  location in memory and the segment locations in memory.
	  Finally, validation of the ELF is done at run time, once you have
	  flashed the FLASH and rebooted the machine. Boot time is really
	  not the time you want to find out your ELF payload is broken.

	  With this option, LinuxBIOS will direct lar to break each ELF
	  segment into a LAR entry. ELF will not be used at all. Note that
	  (for now) LinuxBIOS is backward compatible -- if you put an ELF
	  payload in, LinuxBIOS can still parse it. We hope to remove ELF
	  entirely in the future.

config PAYLOAD_ELF
	bool "An ELF executable payload file"
	help
	  Select this option if you have a payload image (an ELF file)
	  which LinuxBIOS should run as soon as the basic hardware
	  initialization is completed.

	  You will be able to specify the location and file name of the
	  payload image later.

config PAYLOAD_NONE
	bool "No payload"
	help
	  Select this option if you want to create an "empty" LinuxBIOS
	  ROM image for a certain mainboard, i.e. a LinuxBIOS ROM image
	  which does not yet contain a payload.

	  For such an image to be useful, you have to use the 'lar' tool
	  to add a payload to the ROM image later.

endchoice

config PAYLOAD_FILE
	string "Payload path and filename"
	depends PAYLOAD_ELF || PAYLOAD_PREPARSE_ELF
	default "payload.elf"
	help
	  The path and filename of the ELF executable file to use as payload.
