[. . . ] When you are using dual voltage CPU, JP8 also provides CPU I/O voltage (Vcpuio). The default is 3. 45V.

They are actually the selection of CPU I/O Voltage (Vcpuio). Normally, for single voltage CPU, Vcpuio is equal to Vcore, but for CPU that needs dual voltage such as PP/MT (P55C), Cyrix 6x86L, Vcpuio must be set to Vio, and it is different from Vcore.

Plug in these cables to the onboard power connector in such a way that all the black wires are in the center. The power connector is marked as PWR1 on the system board. Caution: Make sure that the power supply is off before connecting or disconnecting the power cable. Black wire (GND) Red wire (+5V) PWR1 2. 3. 2 CPU Fan Plug in the fan cable to the two-pin fan connector onboard. connector is marked FAN on the system board. The fan GND GND +12V FAN 2-12 Hardware Installation 2. 3. 3 PS/2 Mouse To connect a PS/2 mouse, insert the PS/2 mouse bracket connector to PS2 MS on the system board. Then plug in the PS/2 mouse cable to the mouse port on the bracket.

Plug in the 10-pin flat cable to the appropriate onboard connectors. The serial port 1 connector is marked as COM1 and the serial port 2 connector is marked as COM2 on the system board. 12 12 9 10 9 10 COM1 COM2 2-13 Hardware Installation 2. 3. 5 USB Device (optional) You need a USB bracket to have your system to support additional USB device(s). To attach a USB bracket, simply insert the bracket cable to the onboard USB connector marked as USB.

IDE1 is also known as primary channel and IDE2 as secondary channel, each channel supports two IDE devices that makes total of four devices. In order to work together, the two devices on each channel must be set differently to master and slave mode, either one can be hard disk or CDROM. The setting as master or slave mode depends on the jumper on your IDE device, please refer to your hard disk and CDROM manual accordingly. Connect your first IDE hard disk to master mode of the primary channel. Note: Pressing the Suspend switch allows you to manually force the system to suspend mode. However, this is possible only if the Power Management function in the BIOS Setup menu is enabled. 2-18 Hardware Installation 2. 3. 11 Keyboard The onboard keyboard connector is a five-pin AT-compatible connector marked as KB1. The view angle of drawing shown here is from back panel of the housing. Note: The mini DIN PS/2 keyboard connector is optional. PCB KB1 2-19 Hardware Installation 2. 3. 12 IrDA Connector Serial port 2 can be configured to support wireless infrared module, with this module and application software such as Laplink, user can transfer files to or from laptops, notebooks, PDA and printers. This mainboard supports IrDA (115Kbps, 1 meter) as well as ASK-IR (19. 2Kbps). Install infrared module onto IrDA connector and enable infrared function from BIOS setup, make sure to have correct orientation when you plug onto IrDA connector.

Pin 1 of SIMM The SIMM supported by this mainboard can be identified by 4 kinds of factors: Size: single side, 1Mx32 (4MB), 4Mx32 (16MB), 16Mx32 (64MB), and double side, 1Mx32x2 (8MB), 4Mx32x2 (32MB), 16Mx32x2 (128MB). Speed: 60ns or 70ns access time Type: FPM (Fast page mode) or EDO (Extended data output) Parity: without parity (32 bit wide) or with parity (36 bit wide). Because Pentium processor has 64 bit bus width, the four SIMM sockets are arranged in two banks of two sockets each, they are Bank0 and Bank1. [. . . ] For 32 bit non-parity SIMM using 1M by 4 bit DRAM chip, 32/4=8 chips. For 36 bit parity SIMM using 1M by 4 bit DRAM chip, 36/4=9 chips. For 36 bit parity SIMM using 1M by 4 bit and 1M by 1 bit DRAM, the chip count will be 8 data chips(8= 32/4) plus 4 parity chips(4=4/1), total is 12 chips. Following table list the recommended DRAM combinations: SIMM Data chip 1M by 4 1M by 4 1M by 4 1M by 4 1M by 4 1M by 16 1M by 16 1M by 16 1M by 16 4M by 4 4M by 4 4M by 4 4M by 4 SIMM Parity chip None None 1M by 1 1M by 4 1M by 4 None None 1M by 4 1M by 4 None None 4M by 1 4M by 1 Bit size per side 1Mx32 1Mx32 1Mx36 1Mx36 1Mx36 1Mx32 1Mx32 1Mx36 1Mx36 4Mx32 4Mx32 4Mx36 4Mx36 Single/ Double side x1 x2 x1 x1 x2 x1 x2 x1 x2 x1 x2 x1 x2 Chip count 8 16 12 9 18 2 4 3 6 8 16 12 24 SIMM size 4MB 8MB 4MB 4MB 8MB 4MB 8MB 4MB 8MB 16MB 32MB 16MB 32MB Recommended Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes Yes 2-23 Hardware Installation SIMM Data chip 16M by 4 16M by 4 16M by 4 16M by 4 SIMM Parity chip None None 16M by 4 16M by 4 Bit size per side 16Mx32 16Mx32 16Mx36 16Mx36 Single/ Double side x1 x2 x1 x2 Chip count 8 16 9 18 SIMM size 64MB 128MB 64MB 128MB Recommended Yes, but not tested.
