Well, in my despair, I've tried to play around with the BIOS tools provided in this forum... ...and I found out that if I load the stock M6Va BIOS image into MMTOOL, it says something about an OEM Logo at ID 0E. I was curious and deleted this part of the Image - and surprisingly, the AMI SLIC Modder worked with that pre-modded image! My question to the pros: Was it okay to delete 0E or is it obvious that my modded image won't work? Thanks for your help!
Used latest award flash utility and it worked. Was flashing bios with an older version and slic table was not being added to the bios.
