Hi Stefan, hi List !
I'm glad to report full success (write modified image, erase, rewrite original) using flashrom w/ aforementionned system :
IBM Aptiva 2170-G (actually an ACER V75-M motherboard) ... SiS 5595 southbridge
Here's a verbose (pruned down) log for one write operation. In addition to flashrom's own verification, I did check the "live" contents of flash memory against the "dead" binary image for any discrepancy, finding none.
Thanks again for the nice tool!
