flashrom

Identify, read, write, erase, and verify BIOS/ROM/flash chips

Description

flashrom is a tool for identifying, reading, writing, verifying and erasing flash chips. It's often used to flash BIOS/EFI/coreboot/firmware/optionROM images in-system using a supported mainboard, but it also supports flashing of network cards (NICs), SATA controller cards, and other external devices which can program flash chips.

It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32/40/48, and BGA chips, which use various protocols such as LPC, FWH, parallel flash, or SPI.

The tool can be used to flash BIOS/firmware images for example -- be it proprietary BIOS images or coreboot (previously known as LinuxBIOS) images.

It can also be used to read the current existing BIOS/firmware from a flash chip.

Currently supported programmers include:

  * internal (for in-system flashing in the mainboard)
  * dummy (virtual programmer for testing flashrom)
  * nic3com (for flash ROMs on 3COM network cards)
  * nicrealtek (for flash ROMs on Realtek and SMC 1211 network cards)
  * nicnatsemi (for flash ROMs on National Semiconductor DP838* network cards)
  * nicintel (for parallel flash ROMs on Intel 10/100Mbit network cards)
  * gfxnvidia (for flash ROMs on NVIDIA graphics cards)
  * drkaiser (for flash ROMs on Dr. Kaiser PC-Waechter PCI cards)
  * satasii (for flash ROMs on Silicon Image SATA/IDE controllers)
  * satamv (for flash ROMs on Marvell SATA controllers)
  * atahpt (for flash ROMs on Highpoint ATA/RAID controllers)
  * atavia (for flash ROMs on VIA VT6421A SATA controllers)
  * atapromise (for flash ROMs on Promise PDC2026x ATA/RAID controllers)
  * it8212 (for flash ROMs on ITE IT8212F ATA/RAID controller)
  * ft2232_spi (for SPI flash ROMs attached to an FT2232/FT4232H/FT232H family
