OK....here's the scoop !! Loking to upgrade my friends firmware on a CD-RW that came with his HP system. The drive is marked as a Mitsumi CR-48x5te, while on Mitsumi's web site I only found a drive listed as CR-4805TE. I'm betting that this is the same drive, now here's the problem. The firmware app is calling for a true DOS window, not a DOS prompt. How do we go about doing this in WinXP...if its even possible ?!?!
