Flashrom: Difference between revisions

Revision as of 16:50, 14 March 2007

Flashrom is a utility written for LinuxBIOS and maintained in the LinuxBIOS Subversion repository. It can be used to detect BIOS chips (DIP, PLCC), read their contents and write new contents on the chips ("flashing").

Supported devices

Note: The LinuxBIOSv1 version of Flashrom ("flash_and_burn") only supported a very small number of devices. Always use the latest Flashrom version from LinuxBIOSv2!

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, ICH7/ICH7R, ICH7M, ICH7MDH, ICH8/ICH8R, ICH8DH, and ICH8DO chipsets.
³ Identifying and reading chips seems to work, but there are reports that writing may not work on some mainboards.
⁴ Untested, but should work.

Installation

Requirements

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

In Debian unstable the respective packages are called libpci-dev and zlib1g-dev.

Manual Installation

$ svn co svn://linuxbios.org/repos/trunk/LinuxBIOSv2 
$ cd LinuxBIOSv2/util/flashrom
$ make
$ make install

Debian

$ apt-get install flashrom
