1 Unsupported, disabled by default.
2 This includes the ICH, ICH0, ICH2, ICH2-M, ICH3-S, ICH3-M, ICH4/ICH4-L, ICH4-M, ICH5/ICH5R, ICH6/ICH6R, ICH6-M, ICH7DH, ICH7/ICH7R, ICH7M, ICH7MDH, ICH8/ICH8R, ICH8DH, and ICH8DO chipsets. ICH2: Identifying and reading chips seems to work, but there are reports that writing may not work on some mainboards.
4 Untested, but should work.
5 Only reading the chip, but not writing to it has been tested. Both is expected to work, though.
6 Should work, but only reading (not writing or erasing) the chip has been tested.

Supported mainboards

This is a list of mainboards where we have verified that they either do or do not need any special initialization to make flashrom work (given flashrom supports the respective southbridge and ROM chip), or that they do not yet work at all. If they do not work, support may or may not be added later.

Mainboards which don't appear in the list may or may not work (we don't know, someone has to give it a try). Please report any further verified mainboards on the mailinglist or add them here directly.

1 Used in the IGEL WinNET III thin client.
2 Might also work for other CLE266 based EPIAs.
3 Flashrom works great when booted with the proprietary BIOS. Once booted in coreboot, it does not work reliably. See bug #87.
4 Interestingly flashrom does not work when the vendor BIOS is booted, but it does work flawlessly when the machine is booted with coreboot.
5 See http://www.coreboot.org/pipermail/coreboot/2007-September/025281.html.
6 Used in the IGEL-316 thin client.
7 See http://www.coreboot.org/pipermail/coreboot/2007-October/026496.html.

Installation

Requirements

Flashrom requires the pciutils and zlib and the respective development packages in order to be built.

In Debian unstable these development packages are called pciutils-dev and zlib1g-dev. Most other distributions call them pciutils-devel and zlib-devel.

Manual Installation

$ svn co svn://coreboot.org/repos/trunk/util/flashrom
$ cd flashrom
$ make
$ sudo make install

Debian

$ sudo aptitude install flashrom

Fedora

$ sudo yum install flashrom

Mandriva

$ urpmi flashrom

openSUSE

$ yast -i coreboot-utils

For distributions older than openSUSE Factory (11.0) you find "backports" in the openSUSE Build Service.

Usage

Detect whether flashrom knows about your chipset/mainboard/BIOS chip:

$ flashrom

Read the current BIOS image into a file:

$ flashrom -r backup.bin

Write a BIOS image (proprietary or coreboot) on the ROM chip:

$ flashrom -wv newbios.bin
WARNING: This will overwrite your current BIOS! Make sure you know what you're doing!

For more documentation please see the flashrom README or the manpage.
