I sent this on to support, but thought I'd post it here in case anyone had a work-around I had missed. ----------------------------- I'm running RC3 (3170), and first of all I want to say that I love it! You've done a fantastic job! I have, however, found a way to kill the machine (I was pleasantly surprised it got as far as it did, I have to admit): - Using a TI EZ-430 development kit (a USB dongle with a USB/Serial interface chip) (http://focus.ti.com/docs/toolsw/folders/print/ez430-f2013.html) - Installed the software (downloadable from TI) - plug in the USB device - on the Parallels bar, select Devices/USB/MSP-FET430UIF JTAG Tool - Windows correctly starts the install process - point the device installer to the disc copy of the drivers - drivers start to install for the MSP-FET430UIF (TI USB FET) Adapter - while installing umpf3410.i51 to C\WINDOWS\system32\drivers, the progress bar gets all the way to completion, then the entire screen wipes and gives the lovely multi-lingual "you need to restart your computer"... As I said, I was surprised it got this far, but now I have something to ask for! You guys are doing too good of a job!
