1 CIS 170 Microcomputer Hardware Name: Assignment 5 From the lack of having enough peripherals for this course (at least at this point), we have the necessity of doing some experiments mentally rather than physically. Configure the motherboard for a Intel Pentium V - 512K cache. Turn in the last page with all the jumper settings marked. Jumper Settings You can configure hardware options by setting jumper on the mainboard. See Figure 2-1 for jumper locations. Set a jumper as follows: Short a jumper by placing the plastic jumper cap over two pins of the jumper. Open the pins of a jumper by removing the jumper cap. Symbols: Note: When you open the jumper, attach the plastic jumper cap to one of the pins so you won't lose it. For setting 3-pin -jumpers. the symbols below are used. Pins 1 and 2 are Shorted with a jumper cap. Pins 2 and 3 are Shorted with a jumper cap. For setting 2-pin -jumpers, the following symbols are used: The jumper is Shorted when the jumper cap is placed it over the two pins of the jumper. The jumper is Open when the jumper cap is removed from the jumper. Page 1

2 J4 Power Supply Connectors The power supply connectors are two six-pin male header connectors. Plug the dual connectors from the power directly onto the board connectors. Most of power supply have two leads. Each lead has six wires. Two of which are black, orient the connectors, so the black wires are in the middle. The black wires should be in the middle 1 Power Good 7 Ground 2 +5V DC 8 Ground 3 +12V DC 9-5V DC 4-12V DC 10 +5V DC 5 Ground 11 +5V DC 6 Ground 12 +5V DC COM 1 : Serial Port # 1 COM 2 : Serial Port # 2 PRN 1 : Parallel Port J2 Keyboard Connector A standard five-pin female DIN keyboard connector is located at the rear of the board J2. 1 Keyboard Clock 2 Keyboard Data 3 N.

JP6A, JP6B JP6C - CPU Speed Selectors The mainboard has a clock generator that lets you choose the CPU frequency by settings jumpers JP6A, JP6B, JP6C. You can set the CPU speed to 50/60MHz or 66 MHz as shown below. CPU Speed Jumpers 5OMHz 55MHz 60 MHz 66 MHz 75MHz A B C (Default) Page 4

You must make sure that the cache module follow the specification of Intel COAST 3.0 or later version. Please contract the modules supplier to avoid not working properly or damaging any modules circuits. Page 6
