I think there was a discussion about NT4 last year. Could anyone let me know if I could use 1 MPLAB 3.31 2 ICEPIC add-on for MPLAB 3 ICEPIC32 directly under the NT operating system (without creating a dual boot system into win95), ie just using NT4. My reason for asking is because I am thinking of upgrading my PC to run under NT instead of win95. steve@s.ssystems.easynet.co.uk - http://easyweb.easynet.co.uk/~s.ssystems Stephen H Alsop, S&S Systems Ltd, UK.
