Accesstek DD1203

I have a DD1203 with f/w 120i. The drive was badged I/O Magic when bought. According to Accesstek, this drive is supposed to support HD-Burn. Nero or CopytoDVD doesnt allow me to use the HD-Burn option. I’d like to know if there’s a way I can flash this drive with the 120E firmware instead of the 120i. The f/w download is an executable file that wont allow it to work on a drive with ’ i ’ series f/w. I need another way. Thanks.
