Ollie Lho184a4042005-11-26 21:55:36 +000037 If no file is specified, then all that happens
38 is that flash info is dumped and the flash chip is set to writable.

Stefan Reinauere3f3e2e2008-01-18 15:33:10 +000044Flashrom reads the coreboot table to determine the current mainboard
45(parse DMI as well in future?). If no coreboot table could be read
Uwe Hermann2dc5f422006-11-20 20:32:35 +000046or if you want to override these values, you can specify -m, e.g.:
Ollie Lho184a4042005-11-26 21:55:36 +000047
Uwe Hermann67808fe2007-10-18 00:29:05 +000048 flashrom -w --mainboard AGAMI:ARUMA agami_aruma.rom

Uwe Hermann2dc5f422006-11-20 20:32:35 +000064ROM Layout Support
Ollie Lho184a4042005-11-26 21:55:36 +000065------------------
66
Uwe Hermann2dc5f422006-11-20 20:32:35 +000067Flashrom supports ROM layouts. This allows to flash certain parts of
68the flash chip only. A ROM layout file looks like follows:
Ollie Lho184a4042005-11-26 21:55:36 +000069
70 00000000:00008fff gfxrom
71 00009000:0003ffff normal
72 00040000:0007ffff fallback
73
74 i.e.:
75 startaddr:endaddr name
76
Uwe Hermann67808fe2007-10-18 00:29:05 +000077 All addresses are offsets within the file, not absolute addresses!
Ollie Lho184a4042005-11-26 21:55:36 +000078
Uwe Hermann2dc5f422006-11-20 20:32:35 +000079If you only want to update the normal image in a ROM you can say:
Ollie Lho184a4042005-11-26 21:55:36 +000080
Uwe Hermann67808fe2007-10-18 00:29:05 +000081 flashrom -w --layout rom.layout --image normal agami_aruma.rom
Ollie Lho184a4042005-11-26 21:55:36 +000082
Uwe Hermann2dc5f422006-11-20 20:32:35 +000083To update normal and fallback but leave the VGA BIOS alone, say:
Ollie Lho184a4042005-11-26 21:55:36 +000084
Uwe Hermann67808fe2007-10-18 00:29:05 +000085 flashrom -w -l rom.layout -i normal -i fallback agami_aruma.rom
Ollie Lho184a4042005-11-26 21:55:36 +000086
Uwe Hermann2dc5f422006-11-20 20:32:35 +000087Currently overlapping sections are not supported.
Ollie Lho184a4042005-11-26 21:55:36 +000088
Uwe Hermann2dc5f422006-11-20 20:32:35 +000089ROM layouts should replace the -s and -e option since they are more
90flexible and they should lead to a ROM update file format with the
Uwe Hermann67808fe2007-10-18 00:29:05 +000091ROM layout and the ROM image in one file (cpio, zip or something?).
Ollie Lho184a4042005-11-26 21:55:36 +000092

Uwe Hermann67808fe2007-10-18 00:29:05 +000094Disk on Chip support
95--------------------
Ollie Lho184a4042005-11-26 21:55:36 +000096
Uwe Hermann67808fe2007-10-18 00:29:05 +000097Disk on Chip support is currently disabled since it is considered unstable.
Stefan Reinauercbc55d02006-08-25 19:21:42 +000098Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
