NCR S26 manual Region

Non-PnP ISA Card Configuration

I/O Region

The items under this parameter permit you to reserve 16-byte memory address ranges for non-PnP boards. When the system configures PnP boards, the address ranges that you marked will not be used.

You can assign random memory addresses to non-PnP boards as long as you cover the address range required by the board. For example, for a board that requires 178h-188h address, you have to set regions 170h-17Fh and 180h- 18Fh to Yes.
