'''Flashrom''' is a utility which can be used to detect, read, or write BIOS chips (DIP, PLCC, SPI).

'''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.
Note: There are probably some flash ROM chips which are compatible to the ones listed below.
<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").

'''Flash chips'''
'''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.

This is a list of mainboards where we have verified that they either do or do not need any special initialization to make flashrom work (given flashrom supports the respective southbridge and ROM chip), or that they do not yet work at all. If they do not work, support may or may not be added later.

<!-- List of upcoming events (remove events after they have taken place). -->
Mainboards which don't appear in the list may or may not work (we don't know, someone has to give it a try). Please report any further verified mainboards on the mailinglist or add them here directly.

== Installation ==
'''Requirements'''
Flashrom requires the '''pciutils''' and '''zlib''' and the respective development packages in order to be built.
In Debian unstable these development packages are called '''pciutils-dev''' and '''zlib1g-dev'''. Most other distributions call them '''pciutils-devel''' and '''zlib-devel'''.
'''Manual Installation'''
$ svn co svn://linuxbios.org/repos/trunk/util/flashrom
$ cd flashrom
$ make
$ sudo make install
'''Debian'''
$ sudo aptitude install flashrom
'''Fedora'''
$ sudo yum install flashrom
'''Mandriva'''
$ urpmi flashrom
== Usage ==
Detect whether flashrom knows about your chipset/mainboard/BIOS chip:
$ flashrom
Read the current BIOS image into a file:
$ flashrom -r backup.bin
Write a BIOS image (proprietary or LinuxBIOS) on the ROM chip:
$ flashrom -wv newbios.bin


<div style="color: red">WARNING: This will overwrite your current BIOS! Make sure you know what you're doing!</div>

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.
