Clone ipxe:
 
$ git clone git://git.ipxe.org/ipxe.git
 
Then locate your network card with:
 
# lspci -nnnn
 
it will look like that:
 
[...]
 
00:0c.0 Ethernet controller [0200]: 3Com Corporation 3c905C-TX/TX-M [Tornado] [10b7:9200] (rev 78)
 
[...]
 
Note the pci ids that are here: [10b7:9200]
 
 
 
Ajust your settings in src/config/local/
 
 
 
Then build ipxe:
 
cd ipxe/src/
 
make bin/10b79200.rom
 
 
 
Then backup the existing rom:
 
cd ../../
 
flashrom -pnic3com -r 3com_rom_backup.rom
 
The flashchip size is written in the output of that command.
 
 
 
Then generate a rom that is exactly the size of your rom chip:
 
dd if=/dev/zero of=bin/10b79200.rom.64k bs=1 count=65536
 
dd if=bin/10b79200.rom of=bin/10b79200.rom.64k conv=notrunc

I've no code in flashrom yet, but I made a flashrom compatible arduino programmer and participated in testing and documentation.


My hardware

Mainboard based programmers

Device or programmer Flash chip Test result
Asus M4A785T-M mainboard W25x80 (DIP8)
  • Yes with the BIOS
  • Yes with coreboot
Asrock E350M1 A25L032
  • Yes from coreboot
  • Untested from the BIOS
Lenovo X60 MX25L1605D/MX25L1608D
  • Yes with coreboot.
Lenovo X60
  • Yes with coreboot.
Lenovo X60T MX25L1605D/MX25L1608D
  • Yes with coreboot
Lenovo T60 MX25L1605D/MX25L1608D
  • Yes with coreboot
PCEngines Alix.1c
  • Yes with coreboot
  • Yes with the recovery LPC dongle
Asus N71JQ
  • Requires some bit flippings(with ifdtool and an external programmer) in the flash descriptor.
  • Not tested internally.

External programmers

Device or programmer Status
Arduino uno (serprog)
  • Requires a 5v->3.3v level shifter for most current flash chips.
  • Issues with the 8u2/8u3 when using the serial port at high speed.
Arduino duemillanove (serprog)
  • Requires a 5v->3.3v level shifter for most current flash chips.
  • Works fine otherwise.
Arduino Due ( no support for it yet )
  • 3.3v level output on SPI.
  • Not working: No support for it yet.
openmoko debug board (ft2232_spi:type=openmoko)
  • Works fine
3com PCI NIC (10b7:9200) (nic3com)
  • Works fine
Sata SII PCI card
  • writing and erasing worked fine.
Really old PCI realtek cards
  • No parallel chip to test
Some GNU/Linux embedded boards (linux_spi)
  • Backporting some mainline kernel patches is required on some very old (2.6.35) kernel for omap3.
  • Works fine otherwise
An atahpt PCI card
  • Didn't work when adding the PCI IDS, but the atahpt is known not to work according to the mailing list.
old AGP Nvidia card
  • Worked with a patch (documented below)
Nvidia geforce 210 PCIe 16x card
  • didn't work when adding the PIC IDs

I've also the following hardware:

  • pomona clip for recovering my x60
  • some chips(2MB SO8(currently soldered), 16MB SO8)

Work in progress for the wiki

Don't try that, it's dangerous!!!!
