'''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 parallel, LPC, FWH and SPI flash interfaces.
+
<small>
* Supports more than 150 flash chip families and half a dozen variants of each family.
+
* Supports more than 476 flash chips, 291 chipsets, 500 mainboards, 79 PCI devices, 17 USB devices and various parallel/serial port-based programmers.
* Flash chip package agnostic. DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40 and more have all been verified to work.
+
* 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)
* Supports more than 75 different chipsets, some with multiple flash controllers.
+
* No physical access needed, root access is sufficient (not needed for some programmers).
* Features special mainboard enabling code for dozens of nonstandard mainboards.
 
* 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 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.

* 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.
 
* 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.
* Supports Linux, FreeBSD, DragonFly BSD, Solaris, Mac OS X, and other Unix-like OSes.
+
* '''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").

'''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://chat.freenode.net/#flashrom freenode.net], [http://webchat.freenode.net/?channels=flashrom&uio=d4 webchat]) or [[Mailinglist|email]]. Please allow for a few hours until someone responds on IRC, we're all volunteers.

'''<span style="font-variant:small-caps; font-size:120%">[[Current events|Upcoming Events]]</span>'''<hr />
In general, it is very likely that flashrom works out of the box even if your mainboard is not listed below.
+
-->
 
+
<!-- List of upcoming events (remove events after they have taken place). -->
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.
 
 
 
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 mailing list or add them here directly.

{{#widget:Ohloh Project|id=flashrom|type=basic_stats}}
'''Requirements'''
 
 
 
Flashrom requires the '''pciutils''' and '''zlib''' and the respective development packages in order to be built. In addition, the '''subversion''' package is required to download it.
 
 
 
In Debian unstable these development packages are called '''pciutils-dev'''/'''libpci-dev''', '''zlib1g-dev''', and '''subversion'''. Most other distributions call them '''pciutils-devel''', '''zlib-devel''', and '''subversion'''.
 
 
 
'''Manual Installation'''
 
 
 
$ svn co svn://coreboot.org/flashrom/trunk flashrom
 
$ cd flashrom
 
$ make
 
$ sudo make install
 
 
 
'''Debian'''
 
 
 
$ sudo aptitude install flashrom
 
 
 
'''Fedora'''
 
 
 
$ sudo yum install flashrom
 
 
 
'''Gentoo'''
 
 
 
$ emerge flashrom
 
 
 
'''Mandriva'''
 
 
 
$ urpmi flashrom
 
 
 
'''openSUSE'''
 
 
 
$ yast -i coreboot-utils
 
 
 
For distributions older than openSUSE Factory (11.0) you find "backports" in the [http://packages.opensuse-community.org/index.jsp?searchTerm=coreboot-utils openSUSE Build Service].
 
 
 
'''T2 SDE'''
 
 
 
Installation from source:
 
$ Emerge-Pkg flashrom
 
 
 
Installation of binaries:
 
$ mine -i flashrom-0.9.0.tar.bz2
 
 
 
'''Windows'''
 
 
 
There is a Windows port of the flashrom utility. Download the latest version at http://google-summer-of-code-2007-coresystems.googlecode.com/files/DarmawanMappatutu_Salihun.tar.gz
 
 
 
== Usage ==
 
 
 
Detect whether flashrom knows about your chipset/mainboard/BIOS chip:
 
 
 
$ flashrom
 
 
 
Read the current BIOS image into a file:
 
 
 
$ flashrom -r backup.bin
 
 
 
Depening on the chip driver, you may have to erase the chip before writing:
 
 
 
$ flashrom -E
 
 
 
Write a BIOS image (proprietary or coreboot) 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>
 
 
 
For more documentation please see the [http://tracker.coreboot.org/trac/coreboot/browser/trunk/util/flashrom/README flashrom README] or the man page.

Modern mainboards store the BIOS in a reprogrammable flash ROM chip. There are hundreds of different flash ROMs, with variables such as memory size, speed, communication bus (LPC vs. ISA/PCI) and packaging to name just a few. The three most common packages are called DIP, PLCC and TSOP. The BIOS copyright holders often place a fancy sticker on the BIOS chip showing a name or logotype, BIOS version, serial number and copyright notice.

A rectangular black plastic block with lots of pins along the two longer sides of the package. DIP ROMs can be socketed which means they are detachable from the mainboard using physical force. Since they haven't been moved in and out of the socket very much (yet, hehe) they can appear to be quite difficult to release from the socket. One way to remove a DIP from a socket is by prying a thin screwdriver in between the plastic package and the socket, along the shorter sides where there are no pins, and then gently bending the screwdriver to push the DIP upwards, away from the mainboard. Alternate between the two sides to avoid bending the pins, and don't touch any of the pins with the screwdriver, see FAQ about ESD, electro-static discharge. If the DIP is soldered directly to the mainboard, it has to be desoldered in order to be reprogrammed outside the mainboard. If you do this, it's a good idea to solder a socket to the mainboard instead, to ease any future experiments.

Black plastic block again, but this one is much more square. PLCC is becoming the standard for mainboards because of it's smaller physical size. PLCC can also be socketed or soldered directly to the mainboard. Socketed PLCC chips can be removed using a special PLCC removal tool, or using a piece of nylon line tied in a loop around the chip and pulled swiftly straight up, or bending/prying using small screwdrivers if one is careful. PLCC sockets are often fragile so the screwdriver approach is not recommended. While the nylon line method sounds onorthodox it works well. Desoldering PLCC can be painful without specialized desoldering equipment particularly because PLCC chips have leads on all four sides of the package.

TSOPs are often used in embedded systems where size is important and there is no need for replacement in the field. It is possible to (de)solder TSOPs by hand, but it comes close to wizardry.

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