TN4045C.txt TD - HANGING ON NMI
Category :Pascal
Platform :All
Product :TD 1.x 2.0
Description:
Q. Why does the debugger give me an inital startup message, and
then hang? Sometimes I get a message concerning the NMI.
A. By default the debugger intercepts the NMI in order to allow
one to break into the debugger with a breakout switch. When
the breakout switch is activated an NMI is generated and the
debugger regains control. If your hardware is using the NMI
then there will be a compatibility problem as the debugger
does not chain on the NMI. Run Tdinst and set NMI Intercept
to NO in the Options menu. Be sure to save the changes to
your TD.EXE by selecting SAVE/MODIFY TD.EXE. You must then
erase any tdconfig.td files as they will have the NMI
Intercept set to YES and will overide the setting in TD.EXE.
