This allows flashrom to identify, read, write, erase and verify flash chips on (some) 3COM network cards. The patch uses the external programmer infrastructure, the network card is basically treated as an external flash programmer. Usage: $ ./flashrom -p nic3com flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. No operations were specified. $ ./flashrom -p nic3com -E flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. Erasing flash chip... SUCCESS. $ ./flashrom -p nic3com -wv backup.bin flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. Flash image seems to be a legacy BIOS. Disabling checks. Programming page: 1023 at address: 0x0000ffc0 Verifying flash... VERIFIED. $ ./flashrom -p nic3com -r backup.bin flashrom v0.9.0-r498 Found NIC "3COM 3C905C: EtherLink 10/100 PCI (TX)" (10b7:9200), addr = 0xa400 Calibrating delay loop... OK. Found chip "Atmel AT49BV512" (64 KB) at physical address 0xffff0000. Reading flash... done. I have tested this on actual hardware (see PCI IDs above) and all operations worked fine. Support for other 3COM cards will follow (I added some more which should be supportable by this code, but they're untested so far), as well as support for NICs from other vendors. The patch also adds support for the Atmel AT49BV512 which is soldered onto the 3COM NIC I used for testing. Corresponding to flashrom svn r499.

flashrom README
-------------------------------------------------------------------------------
flashrom is a utility for reading, writing, verifying and erasing flash ROM
chips. It's often used to flash BIOS/coreboot/firmware images.
It supports a wide range of DIP32, PLCC32, DIP8, SO8/SOIC8, TSOP32, and
TSOP40 chips, which use various protocols such as LPC, FWH, parallel flash,
or SPI.
(see http://coreboot.org for details on coreboot)
Build Requirements
------------------
To build flashrom you need to install the following packages or ports:
Linux et al:
* pciutils
* pciutils-devel / pciutils-dev / libpci-dev
* zlib-devel / zlib1g-dev
On FreeBSD, you need the following ports:
* devel/gmake
* devel/libpci
To compile on Linux, use:
make
To compile on FreeBSD, use:
gmake
To compile on Solaris, use:
gmake LDFLAGS="-L$pathtolibpci -lpci -lz" CC="gcc -I$pathtopciheaders" \
CFLAGS=-O2
To compile on DragonFly BSD, use:
ln -s /usr/pkg/include/pciutils pci
gmake CFLAGS=-I. LDFLAGS="-L/usr/pkg/lib -lpci -lz"
To compile and run on Darwin/Mac OS X:
Install DirectIO from coresystems GmbH.
DirectIO is available at http://www.coresystems.de/en/directio.
