User manual ACORP 5VIA77A2

[. . . ] Jumpers with two pins will be shown as for Short (on )and for Open (off). For manufacturing simplicity it may be sharing pins from other groups. Use the diagrams in this manual instead of following the pin layout on the board. Settings with two jumper numbers require that both jumpers be moved together. To connect the pin, simply place a plastic jumper cap over the two pins as diagrammed. 10 / Chapter 3 Installation Real Time Clock (RTC) RAM - JP5 : The CMOS RAM is powered by the onboard button cell battery. [. . . ] It's allowed there are different capacity DIMM module in all DIMM slot. 12 / Chapter 3 Installation DIMM Memory Installation Insert the module (s) as shown. Because the number pins are different on either side of the breaks, the module will only fit in the orientation as shown. SDRAM DIMM modules have different pin contacts on each side and therefore have a higher pin density. 1 down :K/B up:Mouse 1 JP6 JP7 USB CO M1 SOCKET Printer COM 2 MIDI/ GAME/ AUDIO JP1 J6 1 PCI1 AGP1 168 Pin DIMM Socket AGP SOLT FAN2 DIMM IDE 1 J2 2 PCI4 PCI3 PCI2 LAN J3 PCI5 ISA SOLT ISA SLOT1 Chapter3 Installation / 13 JP5 1 FAN3 FDC IR FAN1 88 pins 60 pins 20 pins The Dual Inline Memory Module (DIMM) memory module must be 3. 3v Extended Data Output (EDO) DRAM or SDRAM. You can identify the type of DIMM module by the illustration below: RFU Buffered Unbuffered 5. 0V 3. 3V Reserved DRAM Key Position Voltage Key Position 168 Pin DRAM DIMM Notch Key Definitions The notch on the DIMM module will shift between left, center, or right to identify the type and also to prevent the wrong type to be inserted into the DIMM slot on the Mainboard. You must ask your retailer for Specifications before purchasing. Four clock signals are supported on this mainboard 14 / Chapter 3 Installation CPU Installation The motherboard provides a ZIF socket 370. The CPU that came with the motherboard should have a fan attached to it to prevent overheating . If this is not the case then purchase a fan before you turn on your system. To install a CPU , first turn off your system and remove its cover. Locate the ZIF socket and open it by first pulling the lever sideways away from the socket then upwards to a 90-degree right angle. Insert the CPU with the correct orientation shown . Parallel Printer port You can enable the parallel port and choose the IRQ through " Onboard Parallel Port" in Chipset. Universal Serial BUS Ports 1 & 2 Two USB ports are available for connecting USB devices. Floppy drive connector This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plus on the other end to the floppy drives. 18 / Chapter 3 Installation 7. FAN1 , FAN2 , FAN3 CPU Cooling Fan (FAN/PWR) These connectors support cooling fans of 500mAmp (6Watt) or less. Orientate the fans so that the heatsink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan's plug to the board taking into consideration the polarity of this connector. 1 down :K/B up:Mouse 1 JP6 JP7 USB C OM 1 SOCKET Printer COM2 MIDI/ GAME/ AUDIO JP1 AGP SOLT FAN2 J6 1 PCI1 AGP1 DIMM FAN1/2/3 CPU Cooling FAN Pin Description 1 Ground P1 P2 2 +12VDC P3 3 Signal IDE FDC FAN3 IR 1 J2 2 LAN J3 PCI5 PCI4 PCI3 PCI2 NOTE : The "Rotation" signal is to be used only by a specially designed fan with rotation signal. WARNING : The CPU and/or motherboard will overheat if there is no air flowing across the CPU and onboard heatsinks. Damage may occur to the motherboard and/or the CPU fan if these pins are incorrectly used. These are not jumpers, do not place jumper caps over these pins.

[. . . ] You must also configure the setting through UART2 Use Infrared" in Chipset Feature Setup to select whether UART2 is directed for use with COM2 or IrDA. Use the five pins as shown on the Back View and connect a ribbon cable from the module to the motherboard according to the pin definitions. 1 up:Mouse USB CO M1 SOCKET 1 down :K/B JP6 JP7 Printer COM2 MIDI/ GAME/ AUDIO JP1 AGP SOLT FAN2 J6 1 PCI1 AGP1 DIMM IDE IrDA/Fast IR Connector Pin 1 2 3 4 5 Description VCC Option IRRX2 Ground IRTX2 LAN 1 J2 2 PCI4 PCI3 PCI2 J3 PCI5 ISA SOLT ISA SLOT1 Chapter3 Installation / 21 JP5 1 FAN3 FDC IR FAN1 10.
