Flashrom Description
Read, write, erase, and verify flash ROM chips flashrom is a utility for identifying, writing, reading, verifying and erasing flash chips. It's often used to flash BIOS/EFI/coreboot/firmware images.IMPORTANT: If something went wrong during flashing, do NOT turn off/reboot your computer. Instead, let us help you recover. We can be contacted via IRC (#flashrom on irc.freenode.net). Please allow for a few hours until someone responds on IRC, we're all volunteers. Here are some key features of "Flashrom": · Supports more than 205 flash chips, 75 chipsets, 130 mainboards, and 17 devices (PCI or USB) 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, TSOP48, 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. Requirements: · pciutils · zlib · libftdi · Subversion What's New in This Release: · Support for external flashers: 3Com NICs, SiI SATA controllers, ITE IT87* SuperI/Os, FT2232H/FT4232H based SPI serial adapters, AVR based flasher (with AVR source code), Dummy tracing flasher · Universal external flasher protocol · Automatic write/erase verification · Dozens of added flash chips, chipsets, mainboards · No root privileges needed for most external flashers · Improved more verbose user interface · Speedups: Fast bus type dependent probing, 100x faster write for some chips · Reliability fixes for buggy hardware, corner case spec conformance
