Flashprog

flashprog 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 570 flash chips, 410 chipsets, 520 tested mainboards, 79 PCI devices, 30 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 flashprog output and error codes. Speed. flashprog 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 (#flashprog on libera.chat, webchat) or email. Please allow for a few hours until someone responds on IRC, we're all volunteers. Attention external SPI programmers: 1.8V SPI chips are becoming more and more common. Please make sure to always use a compatible programmer or voltage adapter. We list the supported voltage range of each chip to the best of our knowledge in the list of supported hardware. X About Find out more about flashprog.
