hello again!
so basically flashrom works as intended on the abit nf7? you have
used the wrong file the first time, but were able to recover it
with
hot flashing. which file did you use then? the backup, the content
of
the flash chip of the second board or some other file? do you know
the
exact revision of the board? there should be a sticker near the
pci
slots with that information on it.

Hi,<br>
yes, flashrom works correctly. My problem was caused due to my
misinterpretation: I supposed the file named nf7_28.bin providing
users to flash motherboard BIOS is a simple binary dump. However its
structure didn't match my actual BIOS i have read back, I still
suppused it must be good. This wrong idea was supported by two
facts:<br>
1. I found from 3 different sources with the same binary content
(nf7_28.bin)<br>
2. On my computer I found an old and forgotten file named
Nf72_15.bin - int was kept in a directory named bios.<br>
<br>
Examining these files I found at 0x7E000 in both file a string: <b>Award
BootBlock BIOS</b> and what is strange, my actual bios - read back
from the chip - also consisted this string at the same address. So
against of the different page0, I said myself it must be a good
BIOS.<br>
But it was a killer....<br>
<br>
Then we recovered my computer as follows:<br>
- from another NF7 motherboard inserted a BIOS chip into my
motherboard and booted.<br>
- usind flashrom, saved the BIOS content into a file called abit.bin<br>
- Without shitching power off, removed the good BIOS chip and
inserted mine.<br>
- usind flashrom again, wrote the chip with the abit.bin file<br>
- verifyed - it was ok<br>
- after rebooting my motherboard was operating<br>
<br>
It means flasrom was verified for correct reading, writing and even
verify was proven. To let you to examine my theory I have attached 3
files:<br>
Nf72_15.bin is an old bios, found on my computer. Probably it was
even used in the old times, but on classic way, i.e. booting from
floppy and using the suggested exe file to download this binary
dump.<br>
nf7_28.bin is probably an appropriate BIOS, but you MUST use the
suggested exe file for fresh up the chip.<br>
If I am right, it means the *.bin files are NOT a straighforward
binary dumps, bot are somehow mixed up to be coded. Meanwhile, the
suggested exe file acts not only a programmer but it even decodes
the scrambled file.<br>
The attached abit.bin is my actual bios, which was read by flasrom
from another chip and was written back to my chip.<br>
<br>
So my conclusion is: users should be careful downloading *.bin files
found on the internet, because they seem to be coded and your
innocent flashrom will be suspected if somebody kills his
motherboard - as I did. Flashrom is correct, but if it fed by
stupidity, it writes stupidity - so simple.<br>
<br>
The revision code is NF7-S v2.0<br>
Cheers, Istvan<br>
