Dear Stefan
thanks for your feedback. Let me put down my story, it may be useful for others: Not all *.bin files are appropriate to download!
If you think so, maybe a warning should be done on your site.
As Abit has disappeared, I downloaded a self-extracting file from a secondary site.
<http://www.updatesdriver.com/download/5918/Abit%20Abit%20NF7%20Bios%20v%2028/Abit%20NF7-M%20Bios%20v%2028/Ab.../>
It contained the BIOS upgrade called nf7_28.BIN and others:
nf728/RUNME.BAT,1KB,2004-9-29 16:10:52
nf728/NF7_28.TXT,2KB,2004-9-29 16:14:54
nf728/nf7_28.BIN,512KB,2004-9-22 17:52:50
nf728/AWDFLASH.EXE,43KB,2004-3-9 11:44:12
nf728/ABITFAE.BAT,2KB,2000-12-27 9:59:04
When as I examined the dump I have found strange that page 0 of the chip consists nearly 0xFF - however still at the beginning there was the "Phoenix BIOS" string exactly as it was written in my chip.
To be sure about the content I have downloaded it from two fifferent sites, one of them was
http://www.omicron.hu/?oldal=support&p=/driver-ek/alaplap/abit/nf7/bios/v1x
I have forgotten the address of the other site.
I compared the files of different origins and all of them were bitwise identical. But I was not quiet due to the strange structure and asked a friend of mine about it. I supposed the flash pages are somehow mixed and are mixed back during the flash process.
He couldn't answer as he always used AWDFLAX.EXE to refresh BIOS, but he also said it seems to be a good BIOS, however the structure is really strange.

So I downloaded it by using flashprog. I have read back and it was ok - until I have tried to reboot. :)))

After a week hunting for another NF7 motherboard I could make my mothherboad work again. (We applied hot-swap chip change.)

So let me suggest you to take a warning to your site:
Not all *.bin files are appropriate to download!

Let me send my warm congratulation about your work, it is a grea idea and a nice job!

Cheers,
Istvan

Hi,

it seems I found a working chip with UNTESTED status.
Probing for Winbond W39V040A, 512 KB: probe_jedec_common: id1 0xda, id2 0x3d
Found chip "Winbond W39V040A" (512 KB, LPC) at physical address 0xfff80000.

It was checked in an old NF-7 Abit motherboard as follows:
sudo flashrom -Vr /tmp/backup.bin
The file is attached and seems valid. Some more info about the board:
*-core
	description: Motherboard
	product: NF7-S/NF7,NF7-V (nVidia-nForce2)
	vendor: http://www.abit.com.tw/
	physical id: 0
	version: 2.X,1.0
*-firmware

	physical id: 0
	version: 6.00 PG

I am ready to try writing as well, but cannot Google appropriate
binarí bios :(

"backup.bin" is at http://paste.flashrom.org/view.php?id=1168



Hello István,

thanks for your report!
The flash chip you mentioned is already marked as tested in the current
version (so please update).
Abit has been bankrupt for quite some time and they eventually shut
down their FTP server. I have backed it up, but apparently the
directories for the NF7 are empty, sorry. :/
