[. . . ] Gently insert the CPU into the socket. 4. Pull down the socket lever to lock the CPU into the socket. 5. Attach the heatsink and fan to the CPU. With four-pin fan connector With two-pin fan connector 2-5 Hardware Installation 6. Plug the fan cable onto the two-pin fan connector onboard. The fan connector is marked JP10 on the system board. If your fan cable has four pins, plug it onto the power connector. [. . . ] Follow these steps to install a SIMM: 1. Slip a SIMM at a 45° angle into a socket. If the SIMM does not completely fit into the socket, reverse the SIMM orientation. The SIMM has a curved edge indicating pin 1 that ensures installation in one direction only. curved edge 2-12 Hardware Installation Be careful when inserting or removing SIMMs. Forcing a SIMM in or out of a socket can damage the socket or the SIMM (or both). 2. Gently push the SIMM up until the pegs of the socket slip into the holes on the SIMM and the holding clips lock the SIMM into a vertical position. The SIMM should be at a 90angle when installed. 2. 7. 2 Removing a SIMM To remove a SIMM: 1. Press the holding clips on both sides of the SIMM outward to release it. Press the SIMM downward to about a 45° angle. Gently pull the SIMM out of the socket. 2. 3. 2-13 Hardware Installation 2. 8 Customizing your Hardware Setup You may customize your hardware setup according to your desired system performance. However, doing so requires resetting of several jumpers. The onboard jumpers are normally set to its default setting. See the figure in section 2. 2 for the location of the jumpers on the system board. The following sections tell how to configure the system board to meet the desired performance: 2. 8. 1 Selecting the IR Module Type The connector marked CN13 lets you select the Infrared (IR) module type that you wish to install. The IR module enables the system to support the remote file transfer function. CN13 115. 2 Kbit (5V) 4 Mbit (3. 3V) 2. 8. 2 Selecting the ECP DMA Channel The ECP DMA channel selections depend FOR SMC 665 I/O CONTROLLER on the onboard I/O controller. The board JP4 JP5 may come either with SMC 665 or SMC 669 I/O controller. If you have SMC 665 controller, then you may set a DMA DMA channel 3 (default) channel for the ECP function. The DMA channel 1 default is DMA channel 3. To select DMA channel 1, reset jumpersJP4 and JP5 to 2-3. If you have SMC 669, leave both jumpers open. 2-14 Hardware Installation 2. 8. 3 Disabling the Onboard Super I/O Controller The board is preset by the manufacturer with the onboard I/O controller enabled. In case you wish to use an external I/O controller, you need to disable the onboard I/O before the external I/O card functions. To disable, you need to reset jumper JP6 to 2-3. JP6 Enabled (default) Disabled 2. 8. 4 Setting the Keyboard Clock By default, the keyboard clock is set to 8 MHz. However, you may increase it to 12 MHz by simply resetting jumper CN15 to 2-3. 8 MHz (default) CN15 12 MHz 2. 8. 5 Disabling the PS/2 Mouse Function The PS/2 mouse function is normally enabled and occupies IRQ12. [. . . ] This connector also supports two IDE devices. You may connect your additional IDE HDD or CD-ROM drive to this interface. To install an IDE CD-ROM drive, connect the CD-ROM drive connector to the interface master port. If you have more than two IDE hard disks, connect your third IDE hard disk to the master port. [. . . ]
