-/* atlantic.c: Setup program for AT/LANTIC DP83905 ethercards. */
-/*
- This is a setup and diagnostic program for ISA NE2000 Ethernet adapters.
- It has specific support for configuring the National Semiconductor
- AT/LANTIC DP83905 used in on ISA Ethernet adapters such as the NE2000plus.
- It also works several work-alike chips from other vendors.
-
- This program must be compiled with '-O'.
- If you have unresolved references to e.g. inw(), then you haven't used -O.
- The suggested compile command is at the bottom of this file.
