   | Default settings are shown for use in an ISA machine.      |
   |                                                            |
   | If board is to be used in an EISA machine, set jumpers JP1 |
   | to JP15 and ISA0, ISA1, ISA2 - to pins 1 & 2 closed. An    |
   | EISA configuration utility must also be used to set up the |
   | board.                                                     |
   |                                                            |
   | If using a DX/2 50 or DX/2 66processor, set jumpers JS1 -  |
   | JS4 to "33MHz or less" setting.                            |
