(Reinstated with BIOS setup) The mashine can boot However the BIOS version are still the same and I have seen no other signs that the BIOS was upgraded.please upload the following images to http://paste.flashrom.org - the original backup you have read out before doing the write (should be equal to the one you did at the very beginning i presume) - the image you used in the -l ... -w ... call - the image flashrom reads after issuing the -l -w call (this should be a mixture of the first (the bootblock part) and the second one also i would like to see the log file generated by flashrom -p internal -V -l layout.txt -i main -w <imagename> -o flashrom.log or at least the verbose output. you said the bios version did not change. how did you determine this fact exactly?what was the outcome eventually? i would like to know if i can mark the chipset and mainboard as supported :)
I'm sorry. I will get back to you as soon at I can. Probably within a week. BR -- Simon Rigét Kløvermarksvej 17 Annisse 3200 Helsinge Tlf. 4096 8217
