[. . . ] Pull the cover towards the rear of the chassis and set it down over the chassis. Check that the corners on the rear of the cover fit over the back of the chassis. Secure the top cover to the rear of the chassis with the screw previously removed. Replace the front panel (see "Replacing the Front Panel -- Minitower"). Replace the side covers (see "Replacing the Minitower Side Covers"). Opening the Chassis Floor Before replacing the system memory, processor, system board, or expansion boards, you may need to open the hinged chassis floor and slide out the system board for access to the components. Remove the left side cover (see "Removing the Minitower Side Covers"). Remove the screw locking the chassis floor to the chassis (see the following figure). Grasp the top edge of the chassis floor and pull down to open the floor. Opening the chassis floor also unplugs the system board from its connector on the riser board. Installing Options 5-19 6. Grasp the two board handles and pull the board out further if you cannot access to the components you are upgrading. If you need to replace the board, see "Removing the System Board -- Minitower" later in this chapter. Opening the chassis floor -- minitower A ­ Screw B ­ Top Edge of Floor C ­ Chassis Feet D ­ Chassis Floor Closing the Chassis Floor To close the chassis floor, proceed as follows. If the system board was partially slid out for access to board components, slide it back into the chassis using the two board handles. If the system board was removed, see "Replacing the System Board -- Minitower" for replacement procedures. Pivot the floor up against the chassis and press the floor against the chassis until the floor latches in place. Closing the floor also plugs the system board into the riser board. 5-20 Installing Options 3. Place the system unit upright and swivel the two chassis feet out, perpendicular to the system unit. Replace the left side cover (see "Replacing the Minitower Side Covers"). System Board Options This section describes how to change options on the system board. Procedures described in this section include: T adding memory modules T upgrading the processor T replacing the system board. The following figure shows the locations of the upgrade sockets on the system board. See Chapter 3 for the location of the system board jumper settings. System board sockets A ­ Processor Socket B ­ System Memory Upgrade Sockets Installing Options 5-21 Memory Upgrade Memory upgrades are installed into memory module sockets on the system board. The system board has two module sockets and supports up to 512 MB of non-ECC high-speed memory. The system supports 168-pin SDRAM modules in 32-, 64-, 128-, and 256-MB unbuffered PC100 memory configurations. Use the following guidelines in selecting DIMM types: T memory can be installed in one or two sockets T the size of the DIMMs can vary between sockets T the speed of the DIMMs must match or exceed the processor bus speed T single- and double-sided DIMMs are supported. To determine what configuration of DIMMs to use, see the table "Supported DIMMs. " For sample memory configurations, see the table "Sample DIMM Upgrade Paths. " To locate memory module sockets on the system board, see the previous figure "System board sockets. " To determine the memory you need to purchase for a memory upgrade, see "Checking System Memory.
