flashrom is a utility for identifying, reading, writing, verifying and erasing flash chips. It is designed to flash BIOS, EFI, coreboot, firmware and optionROM images on mainboards, network/graphics/storage controller cards, and various programmer devices. * Supports more than 225 flash chips, 128 chipsets, 186 mainboards, 19 PCI devices, 3 USB devices and all external programmers using the serprog protocol. * Supports parallel, LPC, FWH and SPI flash interfaces and various chip packages (DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40, TSOP48, and more) * No physical access needed, root and /dev/mem access is sufficient. * No bootable floppy disk, bootable CD-ROM or other media needed. * No keyboard or monitor needed. Simply reflash remotely via SSH. * No instant reboot needed. Reflash your chip in a running system, verify it, be happy. The new firmware will be present next time you boot. * Crossflashing and hotflashing is possible as long as the flash chips are electrically and logically compatible (same protocol). Great for recovery. * Scriptability. Reflash a whole pool of identical machines at the same time from the command line. It is recommended to check flashrom output and error codes. * Speed. flashrom is often much faster than most vendor flash tools.
