Flashrom is a software utility published under an open source license that can detect, read, verify, erase, or write EEPROMs using interfaces such as the Low Pin Count (LPC), FWH, parallel, and Serial Peripheral Interface (SPI). It can be used to flash firmware images such as BIOS or coreboot, or to backup existing firmware.
Details
It is free software released under the terms of the GNU General Public License version 2. It has pciutils and zlib as dependencies, and for some programmers also libftdi and libusb.
