This one took me some time to find out.
LinuxBIOS v2 contains a flash utility called "flash_rom". It can be found under LinuxBIOS - in the package under freebios2/util/flash_and_burn.
This utility can be used to flash the bios instead of awdflash.

# ./flash_rom --help
The arguments are:
usage: ./flash_rom [-rwv] [-c chipname] [-s exclude_start] [-e exclude_end] [file]
-r: read flash and save into file
-w: write file into flash (default when file is specified)
-v: verify flash against file
-c: probe only for specified flash chip
-s: exclude start position
-e: exclude end postion
 If no file is specified, then all that happens
 is that flash info is dumped

A tipical flash-session would be:

./flash_rom -r test.bin
The arguments are:
-r
test.bin

You should then reread the installed bios from Flash - and compare it against the one you have just uploaded using:

 diff <newfile> <oldfile>

There should be no difference between the files !
