10To build the flashrom utility you need to have the following packages
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]11installed on your Linux system:

Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]37 If no file is specified, then all that happens
38 is that flash info is dumped and the flash chip is set to writable.

Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]44Flashrom reads the LinuxBIOS table to determine the current mainboard.
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]45(Parse DMI as well in future?) If no LinuxBIOS table could be read
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]46or if you want to override these values, you can specify -m, e.g.:

Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]52------------------
53
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]54Flashrom supports ROM layouts. This allows to flash certain parts of
55the flash chip only. A ROM layout file looks like follows:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]56
57 00000000:00008fff gfxrom
58 00009000:0003ffff normal
59 00040000:0007ffff fallback
60
61 i.e.:
62 startaddr:endaddr name
63
64 all addresses are offsets within the file, not absolute addresses!
65
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]66If you only want to update the normal image in a ROM you can say:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]67
68 flashrom -w --layout rom.layout --image normal island_aruma.rom
69
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]70To update normal and fallback but leave the VGA BIOS alone, say:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]71
72 flashrom -w -l rom.layout -i normal -i fallback island_aruma.rom
73
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]74Currently overlapping sections are not supported.
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]75
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]76ROM layouts should replace the -s and -e option since they are more
77flexible and they should lead to a ROM update file format with the
78ROM layout and the ROM image in one file (cpio, zip or something?)

84DISK on Chip support is currently disabled since it is considered unstable.
Stefan Reinauercbc55d02006-08-25 19:21:42 +0000[diff] [blame]85Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
