Hi Jay,
thanks for your report. It seems the flashrom version you're using is ancient, and you might be hit by a few bugs which were present in versions before 0.9.0. Could you try flashrom 0.9.2 or even latest svn and send the output (as root) of flashrom -V lspci -nnvvvxxx superiotool -deV so we can take a look at your configuration and figure out what's going on? You can skip the superiotool step if superiotool is not installed and/or won't compile.

I installed Flashrom on an older single board computer and read the BIOS to a file which seemed to work fine.
I noticed that both chips were listed on the wiki with ?'s
Atmel AT29C020 256 Parallel ? ? ? ? VIA VT82C686A/B 1106:0686 ?
I then tried to write that file to an identical SBC and got the following feedback:
I thought it was strange that the -wv failed to verify, but -v verified.
Absolutely, but this might be an artifact of the old flashrom version which didn't have the paranoid checks modern flashrom has.
However after rebooting and checking the BIOS setup, nothing had changed.
Is there anything else I might try to get Flashrom to write the new BIOS?
Our goal is to have flashrom run fine everywhere, and reports like yours are crucial for this. Once we have the requested info from you, we can guide you further and/or directly give you a fix.
# ./sbin/flashrom -wv NEWBIOS.bin
Calibrating delay loop... OK.
No coreboot table found.
Found chipset "VT82C686", enabling flash write... OK. At29C020 found at physical address 0xfffc0000. Flash part is At29C020 (256 KB). Flash image seems to be a legacy BIOS. Disabling checks. Programming page: 1023 at address: 0x0003ff00 Verifying flash... FAILED!
# ./sbin/flashrom -v NEWBIOS.bin Calibrating delay loop... OK. No coreboot table found. Found chipset "VT82C686", enabling flash write... OK. At29C020 found at physical address 0xfffc0000.

Yes, this is very odd. I definitely want to know what happened there, and if this also happens with latest flashrom.
Some background of system I'm using:
Phoenix-AwardBIOS v6.00PG 1984-2003
Platform is running Fedora version 9
The EPX-C3-G is a VIA C3-based [...] compliant with the EPIC (Embedded Platform for Industrial Computing) standard.
