Welcome to flashrom
flashrom is a utility for identifying, reading, writing, verifying and erasing flash chips. It's often used to flash BIOS/EFI/coreboot/firmware images.
- Supports more than 160 flash chips, 75 chipsets, 100 mainboards, and 10 PCI devices which can be used as external programmers.
- Supports parallel, LPC, FWH and SPI flash interfaces and various chip packages (DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40 and more)
- No physical access needed, root 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.
- Portability. Supports Linux, FreeBSD, DragonFly? BSD, Solaris, Mac OS X, and other Unix-like OSes.
