Yesterday i received bitsetting firmware (55b2) from pizzaman tested it and it works for me!
drive has to be at secondary master (change f.bat if it’s connected to another port).
i’ve flashed my drive from dos, took a dvd+rw started the utillity, changed booktype, closed utillity, burned with nero 18.104.22.168 and tested the dvd in another pc …it works!
download the software at http://home.tiscali.nl/bc231348/download/bisetting/bitsetting1008.zip
good luck with it!
Another thanks pizzaman!
