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 ERASE FAILED!

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).
