Note 2: Pins #5 and #6 of the DIP Sw itch SW1 are used to setthe Core/Bus (Fraction) ratio of the CPU . The actualcore speed of the CPU is the Host Clock Frequencymultiplied by the Core/Bus ratio. For example:if Host Clock = 66.6MHz

Core/Bus ratio = 3/2then CPU core speed Host Clock x Core/Bus ratio

= 66.6MHz x 3/2= 100MHz

Note 3:To operate properly at least two 72-pin SIMM modulemust be installed in the same bank or the one 168-pinDIMM module must be installed. The system cannotoperate with only one 72-pin SIMM module installed.

Note 4: Only 3.3 V SIMM memory should be installed at thesame time as DIMM memory. Otherwise don't installSIMM memory an d DIMM memory at the same time.Doing so could damage your system.

Note 5: The DIMM bank supports 3.3 V EDO, 3.3 V FP, a nd,unbuffered 3.3VSDRAM . Be sure to adust the J 18, J19,J20 jumpers to the 3.3Vposition before installingDIMM memory.Below, describes J 18, J 19, J20 jumpersettings for the 3.3V and 5V selections.
