| MISCELLANEOUS TECHNICAL NOTES |
|------------------------------------------------------------|
| 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. |
