3.5.2
Designating Parity Error Response
When the parity logic is armed and an error occurs,
one of ten possible interrupts can be generated. The
position of the mini-jump in JP3 allows the user to
select one of eight vectored interrupts (VIO - V17),
one nonvectored interrupt (PINT), or one non-maskable
interrupt (NMI). As shipped, the board is jumpered to
select VI5 as shown in Figure 3-13. This is the North
Star standard required by DOS and other operating
systems.
If you are using other software, you can pick another
interrupt. NMI should only be used as an emergency
service technique. If no interrupt is desired, the
mini-jump can be stored by placing it sideways, as
shown below.
