The flashrom manpage currently says "-w, --write: Write file into flash ROM (default when <file> is specified)". This is no longer true for recent flashrom versions, which only write if you explicitly use the -w option. Proof: $ flashrom coreboot.rom flashrom v0.9.0-r631 No coreboot table found. Found chipset "Intel ICH7/ICH7R", enabling flash write... OK. Found board "Kontron 986LCD-M", enabling flash write... OK. Calibrating delay loop... OK. Found chip "PMC Pm49FL004" (512 KB) at physical address 0xfff80000. No operations were specified. Thus, fix manpage accordingly. Corresponding to flashrom svn r649.

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 http://coreboot.org for details on coreboot)
Packaging
---------
To package flashrom and remove dependencies on subversion, either use
make export
or
make tarball
make export will export all flashrom files from the subversion repository at
revision BASE into a directory named $EXPORTDIR/flashrom-$VERSION-r$SVNREVISION
and will additionally modify the Makefile in that directory to contain the svn
revision of the exported tree.
make tarball will simply tar up the result of make export and gzip compress it.
The snapshot tarballs are the result of make tarball and require no further
processing.
Build Instructions
------------------
To build flashrom you need to install the following packages or ports:
Linux et al:
* pciutils
* pciutils-devel / pciutils-dev / libpci-dev
* zlib-devel / zlib1g-dev
On FreeBSD, you need the following ports:
* devel/gmake
* devel/libpci
To compile on Linux, use:
make
To compile on FreeBSD, use:
gmake
To compile on Solaris, use:
gmake LDFLAGS="-L$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.
Installation
------------
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
