GENERAL FEATURES ________________________________________________________________ PROCESSOR The power of OCEAN HIPPO PRO comes from 80486. It is the state-of-art microprocessor which merges many innovative features on a single chip for advanced applications and operation systems. With such high density, this CPU incorporates as many as new features to make itself the most powerful microprocessor.

GENERAL FEATURES ________________________________________________________________ The cache memory is a 8K bytes, 16 bytes line size, four-way set associative configuration. The hit rate of this configuration is much better than 32K bytes two-way set associative external cache because a four-way set associative architecture provides better performance in a multitasking and multi-processor environment.
Page 16
GENERAL FEATURES ________________________________________________________________ By eliminating the access to external bus, operations with the internal cache can be completed in a single cycle. 80386 at least needs two cycles for an operation. To further increase the rate of data transfer inside the CPU, the internal bus of the cache memory is increased to 128 bits, which is four times of the external bus.
Page 17
GENERAL FEATURES ________________________________________________________________ Internal memory management unit provides a flexible addressing scheme for the next generation operation system. Multitasking, concurrent operation and manipulating huge data base can be accomplished with excellent performance. Paging mechanism is employed to allow powerful operating system to implement virtual memory.
Page 18
GENERAL FEATURES ________________________________________________________________ DYNAMIC CACHE ARCHITECTURE (DCA) DCA (dynamic Cache Architecture) is a new Cache Memory DCA literally boosts the cache memory efficiency by as much as 300 percent over conventional external cache! It is integrated as part of the high speed logic of the motherboard. A 486 system, until now, moves information in the same manner because the software written to take full advantage of the 486's 32 bit wide BUS...
GENERAL FEATURES ________________________________________________________________ VL-IDE (VESA) The VL-IDE interfaces between standard IDE drivers and the VL-Bus. Since the bus data transfer rate is much higher than what IDE drives can support, the drives will dictate the total throughput of the disk subsystem. The user has three speeds to select from normal speed, medium speed and high speed.
GENERAL FEATURES ________________________________________________________________ MEMORY SYSTEM Two banks of DRAMs can be installed on board. So 8 SIMM modules may be installed on your system and the maximum memory size is up to 32MB, 256KB, 1MB and 4MB DRAM SIMM modules are supported.

Chapter 3 Configuring The System ____________________________________________________ Important Note : Turn off the power before installing or replacing any component. INSTALLING PROCESSOR Processor 486DX/P24T overdrive is a PGA devices. There is a 238-pin PGA socket. To install processor, be sure to line up pin 1 of the CPU with pin 1 of the socket as shown below.
Page 27
CONFIGURING THE SYSTEM ________________________________________________________________ Before installing the processor, make sure that all the pins are straight. The pins are very fragile. Once these pins are bent, the processor may be damaged. The Processor P24T or 486DX is automatically detected by the system. It need not to set any jumper.
Important Note : Turn off the power before installing or replacing any component. INSTALLING RAM MODULES OCTEK HIPPO PRO has eight sockets on board for SIMM modules. Whenever you add memory to the motherboard, install four modules at the same time. Also make sure that the chips on the modules face towards the slot for memory expansion board.
CONFIGURING THE SYSTEM ________________________________________________________________ If the BIOS reports an memory error or parity error, drag out the modules and insert them again. If the locking latches are damaged, contact your dealer to replace the socket. CONFIGURATION OF MEMORY The configuration of the memory is very flexible.
CONFIGURING THE SYSTEM ________________________________________________________________ Because of the shadow RAM function, the 384KB memory between 640KB to 1MB can not accessed. So, the memory size found by the system BIOS is not equal to the actual memory size. For example, when there is 4MB on board, the BIOS will show 3712KB.
CONFIGURING THE SYSTEM ________________________________________________________________ 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.

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.
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.
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.
