Flashrom

Flashrom is a utility for identifying, reading, writing, verifying and erasing flash chips. It is designed to flash BIOS/EFI/coreboot/firmware/optionROM images on mainboards, network/graphics/storage controller cards, and various other programmer devices.

• Supports more than 476 flash chips, 291 chipsets, 500 mainboards, 79 PCI devices, 17 USB devices and various parallel/serial port-based programmers.

• Supports parallel, LPC, FWH and SPI flash interfaces and various chip packages (DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40, TSOP48, BGA and more)

• No physical access needed, root access is sufficient (not needed for some programmers).

• 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.

• Portability. Supports DOS, Linux, FreeBSD (including Debian/kFreeBSD), NetBSD, OpenBSD, DragonFlyBSD, anything Solaris-like, Mac OS X, and other Unix-like OSes as well as GNU Hurd. Partial Windows support is available (no internal programmer support at the moment, hence no "BIOS flashing").
