We welcome contributions from every human being, corporate entity or club.
 
 
 
If you want to contribute patches or test reports, please send them to our flashrom [[Mailinglist|mailing list]]. For one-off test reports, you don't have to subscribe, but if you want to contribute patches, we strongly recommend you subscribe to our mailing list to make communication easier.
 
 
 
Flashrom development is volunteer-driven, and our developers tackle the features they're interested in. Most developers have pretty long personal TODO lists, so if you want to suggest a feature, please make sure you have all the datasheets and/or programming guides needed for that feature (preferably without NDA). For testing, our developers usually need physical access to the hardware in question. It also helps to be friendly to the developers.
 
 
 
== Paid support/development ==
 
 
 
Some companies and individual developers offer paid flashrom support and development if you desire a particular feature nobody is working on.

We've been asked repeatedly about a way to donate to the flashrom project. Donations are a great way to show your appreciation for the project (and it may have saved you loads of money for dedicated flash programmer devices). Since this usually involves a lot of paperwork, we're not accepting donations to the project (yet).
 
  
Many of our developers do appreciate flashrom related hardware donations, though.

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.
