I do not implement any RM interrupt routines. Could this be a bios routine or what ???? The code has been lifted from a known working program. There are only two real differences that I see as being possibly relevant. 1) the setting up of the interrupt vectors were moved from the file containing main() into a subroutine of another .c file. (big deal, should be OK ??) 2) I have a different A2D card (same model, just another card) Can someone please give me a pointer to what the error message above means.
