# Switches 2/1 and 2/2: I/O and ROM addresses

Ensure that the I/O locations you select for your Ringnode do not conflict with those used by another adapter installed in your computer.

These switches also control the memory address of the Smartrom socket (if that is enabled by switch 2/3). If the Smartrom socket is disabled, this memory area is not used.
