7Build Requirements

9
10To build the flashrom utility you need to have the following packages
Uwe Hermann2dc5f422006-11-20 20:32:35 +000011installed on your Linux system:
Stefan Reinauer06b2c4d2005-12-01 10:51:08 +000012
13* pciutils
Uwe Hermann83f0db22006-12-20 14:53:22 +000014* pciutils-devel / pciutils-dev
15* zlib-devel / zlib1g-dev

Stefan Reinauerf8337dd2006-08-03 10:49:09 +000021usage: ./flashrom [-rwvEVfh] [-c chipname] [-s exclude_start]
22 [-e exclude_end] [-m vendor:part] [-l file.layout] [-i imagename] [file]
23 -r | --read: read flash and save into file
24 -w | --write: write file into flash (default when
25 file is specified)
26 -v | --verify: verify flash against file
27 -E | --erase: erase flash device
28 -V | --verbose: more verbose output
29 -c | --chip <chipname>: probe only for specified flash chip
30 -s | --estart <addr>: exclude start position
31 -e | --eend <addr>: exclude end postion
Ollie Lho184a4042005-11-26 21:55:36 +000032 -m | --mainboard <vendor:part>: override mainboard settings
Stefan Reinauerf8337dd2006-08-03 10:49:09 +000033 -f | --force: force write without checking image
34 -l | --layout <file.layout>: read rom layout from file
35 -i | --image <name>: only flash image name from flash layout

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.

Uwe Hermann2dc5f422006-11-20 20:32:35 +000041LinuxBIOS Table and Mainboard Identification
Ollie Lho184a4042005-11-26 21:55:36 +000042--------------------------------------------
Ronald G. Minnich5e5f75e2002-01-29 18:21:41 +000043
Uwe Hermann2dc5f422006-11-20 20:32:35 +000044Flashrom reads the LinuxBIOS table to determine the current mainboard.
Ollie Lho184a4042005-11-26 21:55:36 +000045(Parse DMI as well in future?) If no LinuxBIOS 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 Hermann2dc5f422006-11-20 20:32:35 +000048 flashrom -w --mainboard ISLAND:ARUMA island_aruma.rom
Ollie Lho184a4042005-11-26 21:55:36 +000049
Mondrian Nuessleaef1c7c2007-05-03 10:09:23 +000050The following boards require the specification of the board name, if
51no LinuxBIOS table is found:
52
53* IWILL DK8-HTX: use -m iwill:dk8_htx
54* agami Aruma: use -m AGAMI:ARUMA

Uwe Hermann2dc5f422006-11-20 20:32:35 +000057ROM Layout Support
Ollie Lho184a4042005-11-26 21:55:36 +000058------------------
59
Uwe Hermann2dc5f422006-11-20 20:32:35 +000060Flashrom supports ROM layouts. This allows to flash certain parts of
61the flash chip only. A ROM layout file looks like follows:
Ollie Lho184a4042005-11-26 21:55:36 +000062
63 00000000:00008fff gfxrom
64 00009000:0003ffff normal
65 00040000:0007ffff fallback
66
67 i.e.:
68 startaddr:endaddr name
69
70 all addresses are offsets within the file, not absolute addresses!
71
Uwe Hermann2dc5f422006-11-20 20:32:35 +000072If you only want to update the normal image in a ROM you can say:
Ollie Lho184a4042005-11-26 21:55:36 +000073
74 flashrom -w --layout rom.layout --image normal island_aruma.rom
75
Uwe Hermann2dc5f422006-11-20 20:32:35 +000076To update normal and fallback but leave the VGA BIOS alone, say:
Ollie Lho184a4042005-11-26 21:55:36 +000077
78 flashrom -w -l rom.layout -i normal -i fallback island_aruma.rom
79
Uwe Hermann2dc5f422006-11-20 20:32:35 +000080Currently overlapping sections are not supported.
Ollie Lho184a4042005-11-26 21:55:36 +000081
Uwe Hermann2dc5f422006-11-20 20:32:35 +000082ROM layouts should replace the -s and -e option since they are more
83flexible and they should lead to a ROM update file format with the
84ROM layout and the ROM image in one file (cpio, zip or something?)
Ollie Lho184a4042005-11-26 21:55:36 +000085

87DOC support
88-----------
89
90DISK on Chip support is currently disabled since it is considered unstable.
Stefan Reinauercbc55d02006-08-25 19:21:42 +000091Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
