'''Flashrom''' is a utility written for LinuxBIOS and maintained in the [http://tracker.linuxbios.org/trac/LinuxBIOS/browser/trunk/LinuxBIOSv2/util/flashrom LinuxBIOS Subversion repository]. It can be used to detect BIOS chips (DIP, PLCC), read their contents and write new contents on the chips ("flashing").

'''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.
<small>
* Supports more than 476 flash chips, 291 chipsets, 500 mainboards, 79 PCI devices, 17 USB devices and various parallel/serial port-based programmers.
* Supports [[Technology#Communication_bus_protocol|parallel, LPC, FWH and SPI]] flash interfaces and various chip packages ([[Technology#DIP32:_Dual_In-line_Package.2C_32_pins|DIP32]], [[Technology#PLCC32:_Plastic_Leaded_Chip_Carrier.2C_32_pins|PLCC32]], [[Technology#DIP8:_Dual_In-line_Package.2C_8_pins|DIP8]], [[Technology#SO8.2FSOIC8:_Small-Outline_Integrated_Circuit.2C_8_pins|SO8/SOIC8]], [[Technology#TSOP:_Thin_Small-Outline_Package.2C_32.2C_40.2C_or_48_pins|TSOP32, TSOP40, TSOP48]], [[Technology#BGA:_Ball_Grid_Array|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").

=== Emergency help ===


The LinuxBIOSv1 version of Flashrom ("flash_and_burn") only supported a very small number of devices. Always use the latest Flashrom version from LinuxBIOSv2!
'''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 [[Contact#IRC|IRC]] ('''#flashrom''' on [irc://irc.libera.chat/#flashrom libera.chat], [https://web.libera.chat/#flashrom webchat]) or [[Contact#Mailing_List|email]]. Please allow for a few hours until someone responds on IRC, we're all volunteers.

In Debian unstable the respective packages are called '''libpci-dev''' and '''zlib1g-dev'''.
=== Manual Installation ===

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").

Emergency help

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 libera.chat, webchat) or email. Please allow for a few hours until someone responds on IRC, we're all volunteers.
