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.
