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

* 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

Upload new screenshots
Thanks for uploading more screenshots. Please note:
- Your screenshot should contain a typical scene when working with it.
- Take only a screenshot of the respective application and not of your whole desktop (unless the screenshot is meant for a window manager).
- Your screenshots must be in PNG format.
- You can upload multiple images at once.
- Your screenshot need to be approved by the moderators first. You will already see your screenshot but it will not be visible to others instantly. If moderators reject your upload you will get notified next time you visit this site (requires cookies).
- Images larger than 800x600 pixels will automatically be reduced. So don't try to capture too much detail in a screenshot. It may become unreadable. Shrink the applications window if possible.
- Screenshots are made public and can freely be used by anyone.
- Useful programs for making screenshots are shutter, ksnapshot (KDE), gimp, xwd or scrot. See the Debian wiki for more information on how to make screenshots under Debian.
- Please set your language to english so that everybody understands it. If you don't use english by default please start your application from a shell using after setting "export LANG=C".
