Install DirectIO from coresystems GmbH.
DirectIO is available at http://www.coresystems.de/en/directio.
To cross-compile on Linux for DOS:
Get RPMs of the cross compiler from the DJGPP site and install them:
djcross-binutils-2.19.1-10ap.i386.rpm
djcross-gcc-tools-4.4.1-1ap.i686.rpm
djcross-gcc-4.3.2-8ap.i686.rpm
Download pciutils 3.1.5 and apply http://assembler.cz/flashrom/pciutils.patch
Download and compile http://assembler.cz/flashrom/libgetopt/
Compile pciutils, see README.DJGPP for instructions.
Enter the flashrom directory.
../libpci should contain pciutils source and binaries.
../libgetopt should contain getopt.a from libgetopt.
Run either (change settings where appropriate)
make CC=i586-pc-msdosdjgpp-gcc STRIP=i586-pc-msdosdjgpp-strip OS_ARCH=DOS
or (above settings hardcoded)
make djgpp-dos
You might have to add WARNERROR=no to the make command line.
To run flashrom.exe, download http://clio.rice.edu/djgpp/csdpmi7b.zip and
make sure CWSDPMI.EXE is in the current directory.
