Alain, thanks for the tip.. I'm always a bit apprehensive when it comes to flashing things like BIOS and that's why I'm still on the version that came with the board - but I'll look at updating as suggested

Bruce,
I'm trying to port the 4 channel PID thermostat that DT and I were working on and having stripped out most of the USB code and resolved most of the warnings and errors I'm left with one that I can't resolve.

Its the 113 symbol not defined (INT_ENTRY_H) but its shown as in C:\pbp2.60\pbppic.18lib:1205

Anyone hot any ideas... I've looked through the INC files and can't see any ref to INT_ENTRY_H in them
