If no -coreboot table could be read or if you want to override these values, you can -specify -m, e.g.: - - $ flashrom -w --mainboard AGAMI:ARUMA agami_aruma.rom - -See the 'Supported mainboards' section in the output of 'flashrom -L' for -a list of boards which require the specification of the board name, if no -coreboot table is found. - - -ROM Layout Support ------------------- - -flashrom supports ROM layouts. This allows you to flash certain parts of -the flash chip only. A ROM layout file looks like follows: - - 00000000:00008fff gfxrom - 00009000:0003ffff normal - 00040000:0007ffff fallback - - i.e.: - startaddr:endaddr name - - All addresses are offsets within the file, not absolute addresses! - -If you only want to update the normal image in a ROM you can say: - - flashrom -w --layout rom.layout --image normal agami_aruma.rom - -To update normal and fallback but leave the VGA BIOS alone, say: - - flashrom -w -l rom.layout -i normal -i fallback agami_aruma.rom - -Currently overlapping sections are not supported. - -ROM layouts should replace the -s and -e option since they are more -flexible and they should lead to a ROM update file format with the -ROM layout and the ROM image in one file (cpio, zip or something?). - - -Supported Flash Chips / Chipsets / Mainboards ---------------------------------------------- - -Please check the output of 'flashrom -L' for the list of supported -flash chips, chipsets/southbridges, and mainboards. - -See also http://coreboot.org/Flashrom for more details. - |
