   |               MISCELLANEOUS TECHNICAL NOTES                |
   |------------------------------------------------------------|
   | Some versions of this board have two 512KB x 8 DRAM chips  |
   | mounted in place of Bank 0. In such a case the board will  |
   | work without additional memory. In all other cases a pair  |
   |  of 256KB, 1MB, or 4MB SIMM modules must be installed in   |
   |             Bank 0 for the board to function.              |
   |                                                            |
   |    The optional ISA/EISA paddleboard solves the DC-690B    |
   | incompatibility problem with some early PCI mainboards. If |
   | installed, connect CN3 to JP4, and set JP4/jumpers 1-4 in  |
   |                     the open position.                     |
