Release announcement

The flashrom developers are happy to announce the release of flashrom 0.9.3.

flashrom is a utility for reading, writing, erasing and verifying flash ROM chips.

flashrom is designed to update BIOS/EFI/coreboot/firmware/optionROM images on mainboards, network/graphics/storage controller cards, and various programmer devices. It can do so without any special boot procedures and from your normal working environment.

After over nine years of development and constant improvement, we have added support for every BIOS flash ROM technology present on x86 mainboards and every flash ROM chip we ever saw in the wild.

Highlights of flashrom:

  • Parallel, LPC, FWH and SPI flash interfaces.
  • Support for onboard programming and external programmers.
  • Flash chip package agnostic. DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40, TSOP48 and more have all been verified to work.
  • 261 flash chip families and half a dozen variants of each family.
  • 152 different chipsets, some with multiple flash controllers.
  • 259 specifically supported mainboards, many others will work out-of-the-box (but have not yet been reported).
  • 43 PCI devices, 5 USB devices, and some other serial/parallel port devices can be flashed or used for flashing.
  • No physical access needed. root access is sufficient for internal and PCI flashers, normal user access is sufficient for USB and serial flashers.
  • 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 ROM 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 much faster than vendor flash tools.
  • Supports Linux, FreeBSD, NetBSD, OpenBSD, DragonFly BSD, Nexenta, Solaris and Mac OS X. Partial support for DOS (no USB/serial flashers) and Windows (no internal/PCI flashers). Please refer to the README for build instructions.

Thanks go to everyone who contributed to flashrom over the years.

Please note that rewriting your flash chip can be dangerous and flashrom developers make no guarantees whatsoever. That said, many users have successfully replaced proprietary tools such as awdflash, amiflash and afudos with flashrom.

flashrom has its own home page at http://www.flashrom.org/

New major user-visible features:

  • Dozens of newly supported mainboards, chipsets and flash chips.
  • Support for Realtek RTL8139 NICs.
  • Support for National Semiconductor DP83815/DP83816 and DP83820 NICs.
  • Support for Intel Gigabit NIC SPI flashing (does not support Intel NICs with parallel or LPC flash).
  • Support for SPI flashing via the Amontec JTAGkey2.
  • Support for the RayeR SPIPGM parallel-port based SPI flasher.
  • Support for Loongson-2F (MIPS) flashing.
  • Support for OpenBSD.
  • Security checks for some boards with BMC/IPMI/IMC/other components which can interfere with BIOS flashing.
  • Bus Pirate SPI flasher reliability and performance improvements.
  • Added a udev rules file to allow using certain USB-based programmers as non-root user.
  • Slightly changed command line invocation. Please see the man page for details.

Experimental new features:

  • Portability groundwork for PowerPC (big endian) and MIPS (big+little endian), but no full support yet.
  • Support for NVIDIA nForce MCP61/MCP65/MCP67/MCP78S/MCP73/MCP79 SPI flashing.
  • Support for building flashrom against libpayload.

Infrastructural improvements and fixes:

  • Lots of cleanups, refactoring, and readability improvements in the code.
  • Various bugfixes and workarounds for broken third-party software.
  • Various Intel ICH SPI improvements.
  • Various timer calibration related improvements.
  • Multiple SPI reliability and functional improvements.
  • Improved documentation.
