A patched DOS build can be found here:
http://khepri.coresystems.de/~idwer/flashrom/trunk-djgpp-r1247-patchwork-2438/

> Please try it on your hardware.

Ivan: have you tried the patched .exe ? Is this message gone, with that build: "pcilib: Cannot find any working access method." ?
 

If you can't compile flashrom yourself, ask
> on the mailing list or our IRC channel (#flashrom on freenode).
