Locating the Battery A ­ Battery Disassembly and Reassembly 3-23 4. Press down on the battery clip to release the battery from its socket. Removing the Battery A ­ Battery B ­ Clip 5. Remove the battery and discard in accordance with the manufacturer's instructions. !WARNING The battery can explode if it is incorrectly replaced or improperly discarded. Use only the same battery or an equivalent type recommended by the manufacturer when replacing the battery. Lithium acts as a catalyst when exposed to water and causes spontaneous combustion on contact. Discard used batteries according to the manufacturer's instructions. 6. With the positive (+) side facing up, press the new battery into the socket. Replace the left side cover (see "Replacing the Left Side Cover" earlier in this section). Run Setup to reconfigure system parameters (see Section 2, "System Configuration"). 3-24 Disassembly and Reassembly 4 System Board T Connectors, Jumpers, and Sockets T Components T Resources This section describes the locations of connectors, jumpers, and sockets on the system board, including external cable connectors, internal board connectors, jumper locations, and upgrade sockets. Included in this section are procedures for setting jumpers on the system board and a DIMM memory upgrade path for the DIMM sockets. Also included are descriptions of system board components, system memory map, and I/O addresses. Connectors, Jumpers, and Sockets The following paragraphs describe the system board external cable connector locations, internal board connector locations, jumper locations, and upgrade sockets. Included are procedures for setting jumpers on the system board and a table showing the upgrade path for the DIMM sockets. External Cable Connectors Locations of the external cable connectors on the system board at the back of the system unit are shown in the following figure. For descriptions of the connectors, see Section 1, "System Overview. " System Board External Cable Connector Locations A ­ Mouse Port B ­ Keyboard Port C ­ USB Port D ­ Serial Port 1 E ­ Serial Port 2 F ­ Line Out Jack G ­ Line In Jack H ­ Microphone In Jack I ­ Printer Port J ­ MIDI Port 4-2 System Board Internal Connectors and Sockets Locations of the internal connectors and sockets on the system board are shown in the following figure.

The following figure shows the location of the jumper blocks on the system board. (The factoryset jumper settings are included in Section 2, "System Configuration. ") System Board 4-3 Locating System Board Jumpers A ­ Power On Mode Jumper JP1 B ­ Processor/Bus Speed Jumpers SW1 C ­ Clear CMOS Jumper JBAT1 D ­ Wake-On LAN Jumper JWOL Changing Processor Speed To change processor speed, the system must be jumpered for the correct processor/bus speed. Use the following steps to change the processor/bus speed after installing an upgrade processor. !CAUTION Jumpers are set correctly at the factory for the system configuration. Only change (or check) the appropriate jumper setting if upgrading the processor. 1. WARNING System power must be off before changing a jumper setting. 2. Remove the left side cover (see "Removing the Left Side Cover" in Section 3). Use needle nose pliers to move the jumpers according to the settings shown in the following figure. 4-4 System Board Processor Jumper Settings 233 MHz/66 MHz 350 MHz/100 MHz 366 MHz/66 MHz 266 MHz/66 MHz 400 MHz/100 MHz 400 MHz/66 MHz 300 MHz/66 MHz 450 MHz/100 MHz 433 MHz/66 MHz 333 MHz/66 MHz 500 MHz/100 MHz 5. Replace the left side cover (see "Replacing the Left Side Cover" in Section 3). [. . . ] Writeback caching yields somewhat better performance than write-through caching because it reduces the number of write operations to main memory. Write-through characterizes a cache strategy where data is always written into system memory when data is written by the CPU. See cache and write back. 16 Glossary Index A Addresses parallel port, 2-3 Advanced menu (BIOS), 2-13 AGP board, 1-11 features, 4-16 removal, 3-9 Application and Driver CD using, 2-26 Audio features,
