The following will describe all of the DIP Switch that you are required to set before moving on to step 2. Note: The DIP Switch as depicted as shown (Figure 1) in their correct physical orientation.

The DIMMs can be either EDO (Enhanced Data Out) or SDRAM (Synchronized DRAM). · DIMM SDRAM may be 83MHz (12ns), 100MHz (10ns) or 120MHz (8ns) bus speed. · If you use both 50ns and 60ns memory you must configure your BIOS to read 60ns. · When using Synchronous DRAM we recommend using the 4 clock variety over the 2 clock. Figure 2 and Table 1 show several possible memory configurations using both SIMM and DIMM.

[. . . ] Using the Soft-Off by Pwr-BTTN feature, you can choose either Instant Off (turns system off immediately), or 4 sec delay (you need to hold the button down for 4 seconds before the system turns off). When the system is in 4 sec delay mode, 2theMax has added a special feature to make the system go into suspend mode when the button is pressed momentarily. Page 9 [. . . ]
