Removing and Replacing the System Board Assembly

When installing some hardware options, it may be more convenient to remove the system board assembly and place it on a horizontal surface before performing the upgrade. The system board assembly in your computer has been designed to be easily removable.

NOTE: Before removing the system board assembly, write down or print out the system configuration information on the EISA Configuration Utility screens. If you accidentally lose your system configuration settings during the following procedure, you can restore them by referring to the copy of the settings.

Removing the System Board Assembly

The system board assembly consists of the system board and a large metal mounting plate secured by four screws to the right side of the chassis. After the computer cover is removed, the system board assembly can be removed from the chassis as a single unit as follows:

1.Remove the computer cover as described in “Removing the Computer Cover,” earlier in this chapter.

2.If there are no expansion cards installed, go to step 4. Otherwise, lay the computer on its right side so you can access the expansion cards.

3.Disconnect the cables from the expansion cards, and then remove the expansion cards. See “Removing an Expansion Card” in Chapter 7.

Be sure to label the cables that you disconnect so they can be easily reconnected.

4.Lay the computer on its left side; then remove the four screws from the mounting plate (Figure 6-5).

5.Partially remove the system board assembly from the chassis.

Tilt the system board assembly away from the chas- sis far enough so that you can access the cables and disconnect them as described in the next step.

6.Disconnect the following cables from the system board.

See Figure 7-1 to identify the following connectors on the system board. Disconnect the following cables (if any) connected to them:

PANEL (for the front panel cable)

FLOPPY (for the diskette interface cable)

HDLED (for the hard-disk drive access indica- tor cable)
