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)
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:
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
