GENERAL FEATURES __________________________________ processor control. These instructions are used in protected mode. New operation systems and software can make use of these instructions for their advanced features, such as concurrent operation and virtual memory.
GENERAL FEATURES __________________________________ MATH COPROCESSOR The demand for sophisticated, number-crunching scientific and business applications has rapidly increased in recent years. 80386DX features an integer Arithmetic Logic Unit which only handles simple integer operations such as addition and multiplication. Floating-point operations which are actually utilized by applications must be accomplished through software routines.
GENERAL FEATURES __________________________________ CACHE MEMORY The system performance can not simply be improved by increasing the clock rate of the system. The performance depends on many factors, such as system architecture and memory configuration. A cache memory system with low cost DRAM as main memory and high speed SRAM as cache memory becomes the only choice for high performance system in terms of price and performance.

GENERAL FEATURES __________________________________ In OCTEK JAGUAR V-386DX, a hidden refresh function is provided. When the hidden refresh function is enabled, the CPU will not stop its operation and the memory refresh operation is transparent to the CPU access. The chipset will monitor the whole system. If the CPU is accessing the main memory, the memory refresh operation is postponed and will be carried out when there is no access to main memory.
GENERAL FEATURES __________________________________ SYSTEM FUNCTIONS System functions include : - Interrupt - DMA - Timer - Real time clock - Clock and ready generation - I/O channel control All system functions are 100% compatible to AT standard. I/O channel of OCTEK JAGUAR V-386DX is designed to be compatible with standard AT bus.
Chapter 3 Installing Components _______________________________ Important Note : Turn off the power before installing or replacing any component. INSTALLING MATH COPROCESSOR Math coprocessor 80387 is PGA device and it has 68 pins. To install Math coprocessor, be sure to line up pin 1 of the Math coprocessor with pin 1 of the socket as shown below.
Page 21
INSTALLING COMPONENTS __________________________________ Before installing the Math coprocessor, make sure all the pins are straight. The pins are very fragile. Once these pins are bent, the coprocessor may be damaged. Check whether the system BIOS can find the coprocessor after reset. The system BIOS will display a list of devices on the motherboard after self-test.
INSTALLING COMPONENTS __________________________________ INSTALLING RAM MODULES OCTEK JAGUAR V-386DX has eight sockets for SIMM modules. Whenever adding memory modules to the motherboard, install four modules at the same time. Also make sure that the chips on the modules face toward the memory expansion slot as shown in the next page.
INSTALLING COMPONENTS __________________________________ INSTALLING EXTERNAL BATTERY To back up the information stored in CMOS RAM, an external battery is needed to provide power after the system is turned off. The connector (P8) for the battery is located beside the keyboard connector on the rear of the board.
INSTALLING COMPONENTS __________________________________ CONFIGURATION OF MEMORY The configuration of the memory is very flexible. It can install 256KB , 1MB or 4MB SIMM modules are acceptable. There are several combinations of DRAM types you may consider. So, a basic system can be equipped with fewer memory and the system can be upgraded by installing the extended memory.
INSTALLING COMPONENTS __________________________________ The number of wait state is assigned in the BIOS setup. Improper setting may cause system malfunction. In this case, reset the CMOS setup using JP3. Then reset the system and go through the system setup again. DRAM CONFIGURATION Bank Bank...
INSTALLING COMPONENTS __________________________________ CONTROL OF SYSTEM SPEED System speed can be controlled by hardware switch and keyboard. Connector P3 is connected to the turbo switch of the case. When the system speed is fast, the turbo LED of the case should be turned on. To change the speed by keyboard, use '-' and '+' of the numeric keypad.

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.
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. Use a pencil eraser to clean the "golden finger"...
Appendix B Troubleshooting _______________________________ SYSTEM UNSTABLE If the system hangs after memory test, possible cause is the improper setting of wait state for memory operation. The number of wait state must match the speed of the DRAM. Reset the CMOS RAM and set up the wait state.
