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.

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?

# ./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.

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, EPIC-compatible single board computer (SBC). C3 processors have extremely low power dissipation which allows fanless operation, making them ideal for industrial applications. The board is configured with a 733MHz or 1GHz MMXcompatible CPU with up to 512MB of PC133 SDRAM plus a CompactFlash socket. Also, a 10/100 Ethernet controller, USB 2.0, 4X AGP video with CRT/flat panel/LVDS interfaces, four serial COM channels, 24 digital I/O lines, AC97 audio, and the standard AT peripheral feature set are included.

The board measures 4.5 x 6.5-inches (115 mm x 165 mm) and is compliant with the EPIC (Embedded Platform for Industrial Computing) standard. It supports expansion options with PC/104 and PC/104-Plus modules or with two high-speed USB 2.0 channels. The board will operate from - 40° to +85°C for rugged applications requiring an embedded PC. Its x86-PC software compatibility assures a wide range of tools to aid in your application’s program development and checkout.
