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

Supported devices

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