Hi Stefan,

Thanks for answering.

Before I did the write I backed up the bios to a file and verified it.    All was OK.    
I then performed a write using a new updated flash bios.    The write failed and also left the flash in a state where the bios will not function.     Verification of the original saved flash now fails.   I have not shutdown the system yet.  Do you need the data   sheet for the SST 49FL008A flash?

The error returned from the write is:
root@sysresccd /mnt/windows/AXIOMTEK % flashrom -VVV -w 84823XH.003 > write.txt
ERASE FAILED at 0x00000000! Expected=0xff, Read=0x40, failed byte count from 0x00000000-0x00000fff: 0x8c2

Your flash chip is in an unknown state.
Get help on IRC at irc.freenode.net (channel #flashrom) or
mail flashrom@flashrom.org with FAILED: your board name in the subject line!

The verbose output from the command above is attached as write.txt

ah. i overlooked the topic sorry.

you wrote that you have read the flash to a file.
was that before or after the (first) write attempt?
if it was before i.e. you have made a backup and it still verifies,
then you should be good. flashrom (even 0.9.3 iirc which was succeeded
lately) should have told you then that nothing has changed when failing
to write.

the output of the failed write would also be very interesting (even
more in verbose mode).
