3Com mode increases the number of available IRQ channels from 4 to 8 and the number of I/O base addresses from 2 to 32. You can install up to six adapters per PC. 3Com drivers are supplied on the TokenDisk diskette to support these 3Com mode enhancements. The default is 3Com mode.

IBM mode provides the same configuration options as
