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!

This flash part has status UNTESTED for operations: PROBE READ ERASE WRITE
The test status of this chip may have been updated in the latest development
version of flashrom. If you are running the latest development version,
please email a report to [email protected] if any of the above operations
work correctly for you with this flash part. Please include the flashrom
output with the additional -V option for all operations you tested (-V, -Vr,
-VE, -Vw), and mention which mainboard or programmer you tested.
Please mention your board in the subject line. Thanks for your help!
