Exactly how do you update the DM42 Firmware?

[Geoff Quickfall]

Well, you give up!

I would keep trying. I am not a c9mputer guru but have noticed the driver issue on the computer is a windows operating system failure, not Swiss Micros. I hate having to tell the computer that I am the administrator.

I have successfully updated the beta unit from the intial to this final version of the firmware. I have never used the PGM pinhole button. My only problems occurred when Windows or Norton security did an update to the system and nixed the driver as unsecured.

Others have had USB cable problems including not being inserted completely into the calculator. The fix involved shaving some of the plastic off the mini USB plug to compensate for the calculators slant at the USB port.
