G586OPC Installing Upgrade CPUs The G586OPC is equipped with a 321-pin Zero Insertion Force (ZIF) socket at location U26 of the system board. This socket is designed for easy removal of the old CPU and easy insertion of the upgrade CPU. The socket allows you to carefully place the new CPU into its position. If you need to apply excessive force to insert the CPU, the installation is being done incorrectly. Warning: Open the socket only if actually installing a CPU.
PCI/ISA System Board as CPUs from other vendors, can be placed incorrectly and will be permanently damaged. Zero Insertion Force (ZIF) Socket To install an upgrade CPU, do the following. 1. Make sure the handle on the side of the ZIF socket is up. To raise the handle, push down, pull it out to the side a little and raise it as far as it will go. The top plate will slide back. Do not use screwdrivers or other tools to open the socket, or damage may occur to the system or socket.
G586OPC Lifting the Handle 2. Once the lever is completely up, remove the old CPU by carefully lifting it straight out of the socket. You are now ready to insert the new CPU.
PCI/ISA System Board 3. Position the CPU above the ZIF socket. Make sure pin 1 of the CPU is aligned with pin 1 of the socket. Lower the chip until the pins are inserted properly in their corresponding holes. Remember that very little force is needed to install the CPU. If the CPU will not insert easily, verify pin 1 of the CPU is aligned with pin 1 of the socket. Applying too much pressure can damage the CPU or the socket. Positioning the CPU Above the ZIF Socket 4.
G586OPC Clearance Requirements The 3.3V Pentium Upgrade Processor comes with a heat sink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the processor and sink require certain space clearances. The clearance above 3.3V Pentium Upgrade Processor's fan/heat-sink must be at least 0.4 in. The clearance on at least 3 of 4 sides of the processor must be at least 0.2 in. The cables (for floppy drive, hard drive, CD-ROM, etc.
PCI/ISA System Board Built-in Ports The G586OPC system board is equipped with two serial ports, one SPP/EPP/ECP parallel printer port, one FDD connector, one PS/2 mouse port and two IDE hard disk shrouded headers.
G586OPC Serial Ports The built-in serial ports are RS-232C asynchronous communication ports with 16C550A-compatible UARTs that can be used with modems, serial printers, remote display terminals, and other serial devices. They use the following system I/O addresses: Port Configuration I/O Address COM1 COM2 COM3/COM4 3F8h 2F8h 3E8h/2E8h Connecting the Serial Ports Two DB-9P serial port cables are provided with the motherboard. They are mounted on a card-edge bracket along with the PS/2 mouse cable.
PCI/ISA System Board The Primary and Secondary Serial Ports on the G586OPC System Board PS/2 Mouse Port The PS/2 mouse port is a 6-pin connector on the system board. Attach the 6-pin mouse port cable, which came in the G586OPC box, to Connector J1. Make sure the brown wire on the PS/2 mouse connector aligns with pin 1 of connector J1.
G586OPC The PS/2 Mouse Port on the G586OPC System Board Parallel Port The G586OPC system board has a standard connector for interfacing your PC to a parallel printer. This port is compatible with both IBM AT printer ports and the new, high speed, bidirectional Extended Capabilities Port standard.
PCI/ISA System Board Connecting the Parallel Printer Port Attach the DB-25S printer port cable, which came with the motherboard, to Connector J7 on the G586OPC system board. Make sure the colored stripe on the ribbon cable aligns with pin 1 of Connector J7. Use a small nutdriver to mount the cable into a DB-25 cutout in the system chassis.
G586OPC Connecting the Floppy Disk Cable The Floppy Disk Connector on the G586OPC System Board Step 1 Install the 34-pin header connector into the floppy disk connector (J8) on the system board. The colored edge of the ribbon should be aligned to pin 1 of the J8 connector. Step 2 Install the other 34-pin header connector(s) into the disk drive(s) with the colored edge of the daisy chained ribbon cable aligned to pin 1 of the drive edge connector(s).
PCI/ISA System Board IDE Hard Disk Interface The G586OPC system board is equipped with two PCI IDE shrouded headers that will interface four IDE (Integrated Drive Electronics) hard disk drives. Note: Only IDE drives can be connected to the IDE interface. Connecting the IDE Hard Disk Interface To prevent improper IDE cable installation, each PCI IDE shrouded header has a keying mechanism.
G586OPC The IDE Hard Disk Connector on the System Board Step 1 If you are connecting two hard drives, install the 40-pin connector of the IDE cable into the primary IDE shrouded header (1st IDE Connector). If you are adding a third or fourth IDE device, install the 40-pin connector of the other IDE cable into the secondary IDE shrouded header (2nd IDE Connector).
PCI/ISA System Board Adding a Second IDE Hard Drive When using two IDE drives, one must be set as the master and the other as the slave. Follow the instructions provided by the drive manufacturer for setting the jumpers and/or switches on the drives. No changes are needed on the G586OPC system board when adding a second hard drive. We recommend that the IDE hard drives be from the same manufacturer. In a few cases, drives from two manufacturers will not function properly when used together.
G586OPC Installing Expansion Cards The G586OPC is equipped with three dedicated PCI and three dedicated ISA slots. One PCI slot and one ISA slot are shared. You can only install a card in one or the other of the shared slots at a time; you cannot install devices in both slots. Due to the size of the the optional synchronous pipeline burst cache module installed in the 160-pin cache module upgrade slot, the length of the card in PCI Slot 2 is limited. Refer to page 27 for limitations.
