  8-bit slot.

       Note: If an 8-bit transfer mode is required and the NIC is
       installed in a 16-bit slot, use forced 8-bit mode. If the NIC is
       to be used in a Novell Netware 386 file server, automatic select
       must be used.

       Note: Alternate ISA bus timing is used if the host computer is not
       100% ISA bus compatible (such as the IBM PS/2 model 30-286) or if
       the Madge Ringnode diagnostics program fails to locate the NIC.
