Page 10: Installing Ram Modules
CPU. INSTALLING RAM MODULES OCTEK HIPPO DCA 1 has four sockets on board for 72pin SIMM modules. The modules should be locked by the sockets. Please check carefully before turning on the power. Otherwise, the system will not work properly.
Page 11: Configuration Of Memory
CONFIGURATION OF MEMORY There are several combinations of DRAM types you may consider. 1Mx32 or 4Mx32 SIMM are acceptable. The memory size is detected automatically by system BIOS and indicated during memory test after reset. No jumper is needed to be set for the memory size and DRAM type.
Page 12: Control Of System Speed
CONTROL OF SYSTEM SPEED System speed can be controlled by keyboard and turbo switch. To change the speed by keyboard, use `-' and `+' of the numeric keypad. Press `Ctrl' `Alt' and `-' for slow speed and press `Ctrl' `Alt' and `+' for fast speed. Connect P1 to the turbo switch of the case and P5 to the turbo LED of the case.

Page 35: Appendix A Operation And Maintenance
Appendix A Operation and Maintenance STATIC ELECTRICITY When installing or removing any add-on card, DRAM module or coprocessor, you should discharge the static electricity on your body. Static electricity is dangerous to electronic device and can build-up on your body. When you touch the add-on card or motherboard, it is likely to damage the device.
Page 36: Cleaning The "Golden Finger
CLEANING THE "GOLDEN FINGER" Whenever inserting an add-on card to the motherboard, make sure that there is no dirt on the "golden finger" of the add -on card. If not, the contact between the "golden finger" and the slot may be poor and thus the add-on card may not work properly.
Page 37: Appendix B Troubleshooting
Appendix B Troubleshooting MAIN MEMORY ERROR After power up, the monitor remains blank, and there are beep sounds indicating a main memory failure. In this case, turn off the power and remove all SIMM modules. Carefully place the modules back to the sockets and make sure that all the modules are locked by the locking latches firmly.
