User manual ACORP 6VIA83 INSTALLATION MANUAL CHAPTER 3

[. . . ] The jumper settings will be described numerically such as [----], [12], [2-3] for no connection, connect pins 1 & 2, and connect pins 2 & 3 respectively. Pin 1 for our mainboard is always on top one or on the left when holding the mainboard with the keyboard away from yourself. "P1" is written besides pin 1 on jumper with three pins. The jumpers will also be shown graphically such as to connect pin 1&2 and to connect 2&3. [. . . ] There will be no worry of wrong CPU voltage detection and no need to re-open the housing if CMOS battery loss. The CPU frequency selection is set by going into: Choose "CPU SPEED SETTING" from the Main Menu and a screen with a list of items appears. CPU Speed Set to Manual user can use the next two items to decide the CPU speed. CPU Ratio This item lets you select the ratio of Core/Bus frequency. Have the following selection: 3x, 3. 5x, 4x, 4. 5x, 5x, 5. 5x, 6x, 6. 5x, 7. 0x, 7. 5x, 8 CPU Freqency This item lets you set external clock (bus clock). The possible settings are 66, 100 and 133 MHZ. . . . Clearance Requirements To maintain proper airflow once the processor is installed on the mainboard, the processor and fan heatsink require certain space clearances. The clearance above the processor must be at least 0. 3 inches. The clearance on at least 3 of 4 sides of the processor and fan heatsink must be at least 0. 2 inches. All cables (for Floppy drive, Hard drive, CD-ROM, and so on) must be routed clear of the processor and its airspace. Fan Exhaust The processor must be kept cool by using a processor with heatsink and fan attached . The temperature of the air filled with the fan/ heatsink cannot exceed 45 OC(113 OF ) . The ambient or room temperature must be below 37 OC ( 99 OF) . 16 / Chapter 3 Installation EXTERNAL CONNECTORS Both Ribbon cable and Connectors on board are with direction signs to avoid that user insert wrong directions. On other hand, the ribbon cables should always be connected with the red stripe on the pin 1 of side of the connector.

PS/2 Keyboard port This connection is for a standard keyboard using an PS/2 plug (mini DIN) . This connector will not allow standard at AT size (large DIN) keyboard plugs. You may use a DIN to mini DIN adapter on standard AT keyboards. PS/2 Mouse port This system will direct IRQ12 to PS/2 mouse. Serial Port COM 1 and COM 2 port The two serial ports can be used for pointing devices or other serial devices. See "Onboard Serial Port" in chipset Feature Setup of the BIOS SOFTWARE. NOTE: Serial {D-type 9pin (F) } must be connected to the serial port. Parallel Printer port You can enable the parallel port and choose the IRQ through " Onboard Parallel Port" in Chipset. [. . . ] The plug from the power supply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned. IMPORTANT: Make sure that the ATX power supply can take at least 10mAmp load on the 5Volt standby lead (5VSB). You may experience difficulty in powering on your system without this.
