I think I'm close to getting this to work. I have a Benq DVD drive, and the VIA VT6421 card, and can get to Reading Bank 0... but it just sits there. I have successfully flashed a Samsung drive with this VIA card, so I know it works. Is there a problem in the USB program, or do I need to evaluate my Benq drive further?
Some people mentioned downgrading the VIA drivers, but I'm on Vista, and the oldest available drivers are not as old as the ones recommended. Plus, do the Windows drivers even matter when you're in DOS? (Or FreeDOS or whatever?)
