1*0d6140beSAndroid Build Coastguard Worker**flashrom** is a utility for identifying, reading, writing, verifying and erasing flash 2*0d6140beSAndroid Build Coastguard Workerchips. It is designed to flash BIOS/EFI/coreboot/firmware/optionROM images on mainboards, 3*0d6140beSAndroid Build Coastguard Workernetwork/graphics/storage controller cards, and various other programmer devices. 4*0d6140beSAndroid Build Coastguard Worker 5*0d6140beSAndroid Build Coastguard Worker* Supports more than 627 flash chips, 407 chipsets, 539 mainboards, 94 PCI devices, 6*0d6140beSAndroid Build Coastguard Worker 30 USB devices and various parallel/serial port-based programmers. 7*0d6140beSAndroid Build Coastguard Worker For more information, see the pages under :doc:`/supported_hw/index`. 8*0d6140beSAndroid Build Coastguard Worker 9*0d6140beSAndroid Build Coastguard Worker* Supports parallel, LPC, FWH and SPI flash interfaces and various chip packages (DIP32, 10*0d6140beSAndroid Build Coastguard Worker PLCC32, DIP8, SO8/SOIC8, TSOP32, TSOP40, TSOP48, BGA and more), see :doc:`user_docs/overview`. 11*0d6140beSAndroid Build Coastguard Worker 12*0d6140beSAndroid Build Coastguard Worker* No physical access needed, root access is sufficient (not needed for some programmers). 13*0d6140beSAndroid Build Coastguard Worker 14*0d6140beSAndroid Build Coastguard Worker* No bootable floppy disk, bootable CD-ROM or other media needed. 15*0d6140beSAndroid Build Coastguard Worker 16*0d6140beSAndroid Build Coastguard Worker* No keyboard or monitor needed. Simply reflash remotely via SSH. 17*0d6140beSAndroid Build Coastguard Worker 18*0d6140beSAndroid Build Coastguard Worker* No instant reboot needed. Reflash your chip in a running system, verify it, be happy. 19*0d6140beSAndroid Build Coastguard Worker The new firmware will be present next time you boot. 20*0d6140beSAndroid Build Coastguard Worker 21*0d6140beSAndroid Build Coastguard Worker* Crossflashing and hotflashing is possible as long as the flash chips are electrically 22*0d6140beSAndroid Build Coastguard Worker and logically compatible (same protocol). Great for recovery. 23*0d6140beSAndroid Build Coastguard Worker 24*0d6140beSAndroid Build Coastguard Worker* Scriptability. Reflash a whole pool of identical machines at the same time from the 25*0d6140beSAndroid Build Coastguard Worker command line. It is recommended to check flashrom output and error codes. 26*0d6140beSAndroid Build Coastguard Worker 27*0d6140beSAndroid Build Coastguard Worker* Speed. flashrom is often much faster than most vendor flash tools. 28*0d6140beSAndroid Build Coastguard Worker 29*0d6140beSAndroid Build Coastguard Worker* Portability. Supports DOS, Linux, FreeBSD (including Debian/kFreeBSD), NetBSD, OpenBSD, 30*0d6140beSAndroid Build Coastguard Worker DragonFlyBSD, anything Solaris-like, Mac OS X, and other Unix-like OSes as well as GNU Hurd. 31*0d6140beSAndroid Build Coastguard Worker Partial Windows support is available (no internal programmer support at the moment, hence 32*0d6140beSAndroid Build Coastguard Worker no "BIOS flashing"). 33*0d6140beSAndroid Build Coastguard Worker 34*0d6140beSAndroid Build Coastguard Worker.. todo:: Convert Technology page and add links here 35*0d6140beSAndroid Build Coastguard Worker 36*0d6140beSAndroid Build Coastguard Worker.. container:: danger, admonition 37*0d6140beSAndroid Build Coastguard Worker 38*0d6140beSAndroid Build Coastguard Worker **Emergency help** 39*0d6140beSAndroid Build Coastguard Worker 40*0d6140beSAndroid Build Coastguard Worker IMPORTANT: If something went wrong during flashing, do NOT turn off/reboot your computer. 41*0d6140beSAndroid Build Coastguard Worker Instead, let us help you recover.
