Carl -

I've corrected my email and am now sending to the group.

I can't use flash coreboot (LinuxBIOS) because our cluster management tools require pxeboot.  We've transitioned away from it.

So, the bios zip file above is correct, but I'm not using it.  It will not work for flashing a chip with LinuxBios.  The way I do this is to do a "flashrom -r" on a system with factory bios and then take that newly created flashrom file and do a "flashrom -w" with it on a board with LinuxBios.    This is the method we used with the old bios_copy software from Linux Networx, but that was extremely unreliable.

The ROM is removeable, so we only potentially trash a PLCC chip.  I have a half dozen or so spares.

Hi Mike,

was it intentional that you only sent the data to me? It would be great
to have that data on the list. If possible, please forward your mail to
the list so other developers can help as well.

I analyzed the output and the only difference is that the new flashrom
version detects the problem and the old version ignores it...

Of course I'd prefer it if you tried to flash coreboot (new name of
LinuxBIOS) to these boards, but that's your choice. Anyway, you said you
have the factory BIOS around somewhere. Is it the one at

Hmm ok. I think we have enough docs to iterate through all possible
board enables. How many of these boards do you have (in case we trash
the ROM of one of them)?
