flashrom README
flashrom is a utility for reading, writing, verifying and erasing flash ROM
chips. It's often used to flash BIOS/EFI/coreboot/firmware 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, and
TSOP40 chips, which use various protocols such as LPC, FWH, parallel flash,
or SPI.
(see for details on coreboot)
To package flashrom and remove dependencies on subversion, either use
make export
make tarball
make export will export all flashrom files from the subversion repository at
revision BASE into a directory named $EXPORTDIR/flashrom-$VERSION-r$SVNREVISION
and will additionally modify the Makefile in that directory to contain the svn
revision of the exported tree.
make tarball will simply tar up the result of make export and gzip compress it.
The snapshot tarballs are the result of make tarball and require no further
Build Instructions
To build flashrom you need to install the following packages or ports:
Linux et al:
* pciutils
* pciutils-devel / pciutils-dev / libpci-dev
* zlib-devel / zlib1g-dev
On FreeBSD, you need the following ports:
* devel/gmake
* devel/libpci
To compile on Linux, use:
To compile on FreeBSD, use:
To compile on Solaris, use:
gmake LDFLAGS="-L$pathtolibpci -lpci -lz" CC="gcc -I$pathtopciheaders" \
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
In order to install flashrom and the manpage into /usr/local, type:
sudo make install
For installation in a different directory use DESTDIR, e.g. like this:
sudo make DESTDIR=/usr install
