'''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.

== Supported mainboards ==
In general, it is very likely that flashrom works out of the box even if your mainboard is not listed below.
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 chipset and flash 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 [[Mailinglist|mailing list]].
'''Known good (worked out of the box)'''
Total amount of boards: '''71'''

== Board notes ==
* ASI MB-5BLMP: Used in the IGEL WinNET III thin client.
* MSI MS-7260 (K9N Neo): Interestingly flashrom does not work when the vendor BIOS is booted, but it ''does'' work flawlessly when the machine is booted with coreboot.
* ASUS M2A-VM: See http://www.coreboot.org/pipermail/coreboot/2007-September/025281.html.
* BCOM WinNET100: Used in the IGEL-316 thin client.
* ASUS A8V-E SE: See http://www.coreboot.org/pipermail/coreboot/2007-October/026496.html.
== Supported laptops/notebooks ==
In general, flashing laptops is more difficult because
* Laptops often use the flash chip for stuff besides the BIOS.
* Laptops often have special protection stuff which has to be handled by flashrom.
* Laptops often use flash translation circuits which need extra drivers in flashrom.

= Flash chip overview =
Modern mainboards store the BIOS in a reprogrammable flash chip. There are hundreds of different flash (EEPROM) chips, with variables such as memory size, speed, communication bus (Parallel, LPC, FWH, SPI) and packaging to name just a few.
==Packaging/housing/form factor==
Probably the only property of flash chips which is completely irrelevant to flashrom.
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.
'''DIP32: Dual In-line Package, 32 pins'''
<gallery>
File:Dip32 chip.jpg
File:Dip32 chip back.jpg
</gallery>
A rectangular black plastic block with lots of pins along the two longer sides of the package. DIP chips 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.
'''PLCC32: Plastic Leaded Chip Carrier, 32 pins'''
<gallery>
File:Plcc32 chip.jpg
File:Plcc32 chip back.jpg
</gallery>
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.
'''DIP8: Dual In-line Package, 8 pins'''
<gallery>
File:Dip8 chip.jpg
File:Dip8 chip back.jpg
</gallery>
'''SO8/SOIC8: Small-Outline Integrated Circuit, 8 pins'''
<gallery>
File:Soic8_chip.jpg
</gallery>
'''TSOP: Thin Small-Outline 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.
==Communication bus protocol==
There are four major communication bus protocols for flash chips, each with multiple subtle variants in the command set:
* Parallel: The oldest flash bus, phased out on mainboards around 2002.
* LPC: Low Pin Count, a standard introduced ca. 1998.
* FWH: Firmware Hub, a variant of the LPC standard introduced at the same time. FWH is a special case variant of LPC with one bit set differently in the memory read/write commands. That means some data sheets mention the chips speak LPC although they will not respond to regular LPC read/write cycles.
* SPI: Serial Peripheral Interface, introduced ca. 2006.
I've tried to create a marketing language -> chip type mapping below:
* JEDEC Flash -> Parallel (well, mostly)
* FWH -> FWH
* Firmware Hub -> FWH
* LPC Firmware -> FWH
* Firmware Memory -> FWH
* Low Pin Count (if Firmware/FWH is not mentioned) -> LPC
* LPC (if Firmware is not mentioned) -> LPC
* Serial Flash -> SPI
SST data sheets have the following conventions:
* LPC Memory Read -> LPC
* Firmware Memory Read -> FWH
If both are mentioned, the chip supports both.
If you're not sure about whether a device is LPC or FWH, look at the read/write cycle definitions.

Generally, a Parallel flash chip will not speak any other protocols. SPI flash chips also don't speak any other protocols. LPC flash chips sometimes speak FWH as well and vice versa, but they will not speak any protocols besides LPC/FWH.
__NOTOC__
__NOEDITSECTION__

Revision as of 09:21, 25 November 2021

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.
