ISA Board Definition
If you have an ISA board with no.CFG file, you can define the board by using the SSU. It
is necessary to define an ISA board only when you want to prevent other boards in the
system from using the same IRQ levels, DMA channels, I/O Port addresses, or Memory
addresses that your ISA board uses. Table A-5 provides some ISA board definitions.
