      Four short flashes                 Timer error

                       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.
