Flashrom README
|
|
-------------------------------------------------------------------------------
|
|
|
|
This is the universal (LinuxBIOS) flash utility.
|
|
|
|
Build Requirements
|
|
------------------
|
|
|
|
To build the flashrom utility you need to have the following packages
|
|
installed on your Linux system:
|
|
|
|
* pciutils
|
|
* pciutils-devel / pciutils-dev
|
|
* zlib-devel / zlib1g-dev
|
|
|
|
|
|
Usage
|
|
-----
|
|
|
|
usage: ./flashrom [-rwvEVfh] [-c chipname] [-s exclude_start]
|
|
[-e exclude_end] [-m vendor:part] [-l file.layout] [-i imagename] [file]
|
|
-r | --read: read flash and save into file
|
|
-w | --write: write file into flash (default when
|
|
file is specified)
|
|
-v | --verify: verify flash against file
|
|
-E | --erase: erase flash device
|
|
-V | --verbose: more verbose output
|
|
-c | --chip <chipname>: probe only for specified flash chip
|
|
-s | --estart <addr>: exclude start position
|
|
-e | --eend <addr>: exclude end postion
|
|
-m | --mainboard <vendor:part>: override mainboard settings
|
|
-f | --force: force write without checking image
|
|
-l | --layout <file.layout>: read rom layout from file
|
|
-i | --image <name>: only flash image name from flash layout
|
|
|
|
If no file is specified, then all that happens
|
|
is that flash info is dumped and the flash chip is set to writable.
|
|
|
|
|
|
LinuxBIOS Table and Mainboard Identification
|
|
--------------------------------------------
|
|
|
|
Flashrom reads the LinuxBIOS table to determine the current mainboard.
|
|
(Parse DMI as well in future?) If no LinuxBIOS table could be read
|
|
or if you want to override these values, you can specify -m, e.g.:
|
|
|
|
flashrom -w --mainboard ISLAND:ARUMA island_aruma.rom
|
|
|
|
The following boards require the specification of the board name, if
|
|
no LinuxBIOS table is found:
|
|
|
|
* IWILL DK8-HTX: use -m iwill:dk8_htx
|
|
* Agami Aruma: use -m AGAMI:ARUMA
|
|
* ASUS P5A: use -m asus:p5a
|
|
* IBM x3455: use -m ibm:x3455
|
|
* EPoX EP-BX3: use -m epox:ep-bx3
|
|
* GIGABYTE GA-M57SLI v2.0: use -m gigabyte:m57sli
|
|
* GIGABYTE GA-M61P-S3: use -m gigabyte:m61ps3
|
|
|
|
ROM Layout Support
|
|
------------------
|
|
|
|
Flashrom supports ROM layouts. This allows 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 island_aruma.rom
|
|
|
|
To update normal and fallback but leave the VGA BIOS alone, say:
|
|
|
|
flashrom -w -l rom.layout -i normal -i fallback island_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?)
|
|
|
|
|
|
DOC support
|
|
-----------
|
|
|
|
DISK on Chip support is currently disabled since it is considered unstable.
|
|
Change CFLAGS in the Makefile to enable it: Remove -DDISABLE_DOC from CFLAGS.
