[comp.sys.ibm.pc] Help needed with IBM PS/2 interrupt handler

arjunb@cs.tamu.edu (Arjun V Bhutkar) (07/10/90)

I need info on the following (please help..):

I have a National Insrtuments MC-DIO-24 Digital I/O Board
installed in an IBM PS/2 model 70. Base address is 2000
and interrupt level is Int_3.
I plan to use Microsoft C _dos_setvect function to write
an interrupt handler for interrupts generated by this board.
However, I am not sure what the number of the interrupt(0-255 ?)
generated is. 
Anybody out there who has done this before? Please e-mail responses.

Thanks in advance..
