Non-PnP ISA Card Configuration
4-20 Using the BIOS Setup Utility
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.
