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 300 flash chips, 220 chipsets, 400
mainboards, 50 PCI devices, 12 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, NetBSD,
OpenBSD, DragonFly BSD, Solaris, Mac OS X, and other Unix-like OSes.
Partial Windows support is available (no internal programmer support at
the moment, hence no "BIOS flashing").
