Installing Upgrade CPUs

The 586IVX is equipped with a 321-pinZero Insertion Force (ZIF) socket at location U29 of the system board. Refer to page 12 for the location of the ZIF socket. This socket is designed for easy removal of an old CPU and easy insertion of an upgrade CPU. The ZIF socket allows you to carefully place the new CPU into its position. If you need to apply excessive force to insert the CPU, you are not installing the CPU correctly.

Warning:

Open the socket only if you are actually installing a CPU. The warranty on the original CPU will be voided if the S/N seal is broken. Before proceeding with the upgrade, take note of the following. The microprocessor and heatsink may be hot if the system has been running. To avoid the possibility of a burn, power the system off and let the processor and heatsink cool for 20 minutes.

The 321-pinZIF socket consists of five rows of pin holes on each side. To prevent improper CPU installation, the ZIF socket has a Plug/Keying mechanism. Several holes in the socket are plugged so that the CPU will go in only one way. If you cannot easily insert the CPU, verify that pin 1 of the CPU is aligned with pin 1 of the socket.

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 it down, slightly pull it out to the side, then raise it as far as it will go. It may be necessary to initially apply a small

21

amount of sideways force to free the handle from its retaining “tab”. Once clear of the “tab”, the handle will open relatively easily. The top plate will slide back. Do not use screwdrivers or other tools to open the socket, or you may damage the system or socket.

Handle

Lifting the Handle

2.Once the lever is completely up, remove the old CPU carefully by lifting it straight out of the socket. You are now ready to insert the new CPU.

Pin 1

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 is not easily inserted, verify whether or not 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.Push the handle down until the handle locks into place. The top plate will slide forward. You will feel some resistance as pressure starts to secure the CPU in the socket. This is normal and will not damage the CPU. However, if the handle is not completely closed, damage to the CPU and/or system board may result.

Installing A Fan/Heatsink

You must choose a fan/heatsink suitable for the processor installed on your system board. Position the fan/heatsink on the CPU such that the air from the side of the fan/heatsink will flow across the heat regulators on the system board. See the figure below.

Clearance Requirements

Your CPU comes with a heatsink mounted on top. To maintain proper airflow once the upgrade is installed on the system board, the CPU and heatsink require certain space clearances. The clearance above the CPU’s fan/heatsink must be at least 0.4 inches. The clearance on at

23

least 3 of 4 sides of the processor and heatsink must be at least 0.2 inches. All cables (for floppy drive, hard drive, CD-ROM,etc.) must be routed clear of the CPU and its airspace.

Fan Exhaust

The CPU must be kept cool by using a fan with heatsink. The temperature of the air entering the fan/heatsink cannot exceed 45oC (113oF). The ambient or room temperature must be below 37oC (99oF).

Floppy Disk Drive Controller

The 586IVX system board is equipped with a shrouded floppy disk header that supports two standard floppy disk drives. You can install any 360KB, 720KB, 1.2MB, 1.44MB, or 2.88MB floppy disk drives. To prevent improper floppy cable installation, the shrouded floppy disk header has a keying mechanism. The 34-pinconnector on the floppy cable can be placed into the header only if pin 1 of the connector is aligned with pin 1 of the header.

Connecting the Floppy Disk Cable

1.Install the 34-pinheader connector into the shrouded floppy disk header (J10) on the system board. The colored edge of the ribbon should be aligned with pin 1 of connector J10.

2.Install the other 34-pinheader connector(s) into the disk drive(s). Align the colored edge of the daisy chained ribbon cable with pin 1 of the drive edge connector(s). Theend-mostconnector should be attached to the drive you want to designate as Drive A.

IDE Hard Disk Interface

The 586IVX system board is equipped with two shrouded PCI IDE headers that will interface four Enhanced IDE (Integrated Drive Electronics) hard disk drives.

Note:

Only Enhanced IDE hard drives or ATAPI CD-ROMscan be connected to the IDE interface.

Connecting the IDE Hard Disk Interface

To prevent improper IDE cable installation, each shrouded PCI IDE header has a keying mechanism. The 40-pinconnector on the IDE cable can be placed into the header only if pin 1 of the connector is aligned with pin 1 of the header.

27

Header

Note:

An IDE cable with a standard 40-pinconnector (without the keying mechanism) can be installed in the shrouded PCI IDE header. Be extremely careful to match the colored edge of the ribbon with pin 1 of the header.

Connecting the Hard Disk Cable

1.If you are connecting two hard drives, install the 40-pinconnector of the IDE cable into the primary shrouded IDE header (connector J11). If you are adding a third or fourth IDE device, install the 40pin connector of the other IDE cable into the secondary shrouded IDE header (connector J12).

2.Install the other 40-pinheader connector(s) into the device with the colored edge of the ribbon cable aligned with pin 1 of the drive edge connector(s).

Note:

Refer to your disk drive user’s manual for information about selecting proper drive switch settings.

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.

28

We recommend that you use Enhanced IDE hard drives from the same manufacturer. In a few cases, drives from two different manufacturers will not function properly when used together. The problem lies in the hard drives, not the 586IVX system board.

Preparing an IDE Drive for Use

IDE disk drives are already low-levelformatted, with anybad-trackerrors entered, when shipped by the drive manufacturer. Do not attempt to do alow-levelformat or you may cause serious damage to the drive. To use an IDE drive, you need to enter the drive type (this information is provided by the drive manufacturer) into the system’s CMOS setup table. Then run FDISK and FORMAT provided with DOS. You may also use the IDE HDD Auto Detection function which will allow the BIOS to auto detect your hard drive type. Refer to the IDE HDD Auto Detection section for details.

Warning:

Do not run FDISK and FORMAT programs on a drive that has already been formatted or you will lose all programs and data stored on the drive.

Using 586IVX with CD-ROMDrives

If you encountered problems while using an ATAPI CD-ROMdrive that is set in Master mode, please set theCD-ROMdrive to Slave mode. Some ATAPICD-ROMsmay not be recognized and cannot be used if incorrectly set in Master mode.

Universal Serial Bus Connectors

The 586IVX system board is equipped with two USB ports on locations J2 and J4 on the system board. USB allows data exchange between your computer and a wide range of simultaneously accessible peripherals. Make sure “USB Controller”in the Integrated Peripherals setup of the Award BIOS is set to Enabled.

29

Installing Expansion Cards

The 586IVX system board is equipped with 3 dedicated PCI slots, 3 dedicated 16-bitISA slots and 1 shared PCI/ISA slot. All PCI slots are bus masters. Refer to page 12 for the locations of the expansion slots.
