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:

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.:

Mondrian Nuessleaef1c7c2007-05-03 10:09:23 +0000[diff] [blame]50The following boards require the specification of the board name, if
51no LinuxBIOS table is found:

Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]58ROM Layout Support
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]59------------------
60
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]61Flashrom supports ROM layouts. This allows to flash certain parts of
62the flash chip only. A ROM layout file looks like follows:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]63
64 00000000:00008fff gfxrom
65 00009000:0003ffff normal
66 00040000:0007ffff fallback
67
68 i.e.:
69 startaddr:endaddr name
70
71 all addresses are offsets within the file, not absolute addresses!
72
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]73If you only want to update the normal image in a ROM you can say:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]74
75 flashrom -w --layout rom.layout --image normal island_aruma.rom
76
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]77To update normal and fallback but leave the VGA BIOS alone, say:
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]78
79 flashrom -w -l rom.layout -i normal -i fallback island_aruma.rom
80
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]81Currently overlapping sections are not supported.
Ollie Lho184a4042005-11-26 21:55:36 +0000[diff] [blame]82
Uwe Hermann2dc5f422006-11-20 20:32:35 +0000[diff] [blame]83ROM layouts should replace the -s and -e option since they are more
84flexible and they should lead to a ROM update file format with the
85ROM layout and the ROM image in one file (cpio, zip or something?)

91DISK on Chip support is currently disabled since it is considered unstable.
Stefan Reinauercbc55d02006-08-25 19:21:42 +0000[diff] [blame]92Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
