Dave,<br><br>This is good information, and actually answer exactly what I was looking for. <br><br>Stefan from the Coreboot project point me to the nvramtool tool. I did test it before I post my question, and I have to agree that the only test I did was the -a switch, and conclude it didn't work. In fact it does work when using the -b option. It create a 256 bytes file, which I assume is similar content.<br>
<br>To validate I ran the following from each command<br>od -Ax -tx1z -v /dev/nvram<br><br>and <br><br>nvramtool -x <br><br>We could see that both have the same 114 bytes pattern produce by /dev/nvram<br><br>Thank to all of you, this will save me a lot of time<br>

Not sure if you can help me on the following, but if I do not ask,
I will not get any answer.<br>
<br>
I have to check +- 400 identical systems. I could do the hardware
section, but the only missing pieces is the BIOS setting.<br>
<br>
I try flashrom on the board without success, but I think you could
help me.<br>
<br>
I wonder if there is a way to dump the BIOS settings from the
memory to a file.<br>
I want to do a checksum on the file, and compare with a master
system.<br>
That way I do not need to decode the settings, but I guess the
checksum will be different if <br>
I have a different configuration.<br>
<br>
Do any of you have an idea, or track I could follow to achieve my
goal.<br>
<br>
This could be a dos, or linux solution.<br>
<br>
Thanks in advance for any help<br>

I needed similar and found it on this link:<br>
<a href="http://www.pixelbeat.org/docs/bios/" target="_blank">http://www.pixelbeat.org/docs/bios/</a><br>
<br>
Essentially (on Linux):<br>
sudo modprobe nvram<br>
sudo dd if=/dev/nvram of=dir/nvram-save/2010-10-26<br>
<br>
... then md5sum in the same script ?<br>
<br>
