Slip a SIMM at a 45° angle with the component side facing down into the socket labeled SIMM-1. Be careful when inserting SIMMs to avoid damaging the SIMM or the socket. 2. Gently press the SIMM up until the pegs of the socket fit into the holes on the SIMM and the holding clips lock the SIMM into position. The SIMM should be at a 90° angle when installed. Figure 1-9 Installing a SIMM 1-12 User's Guide 1. 4. 2 Removing a SIMM Follow these steps to remove a SIMM: 1. Press the holding clips on both sides of the SIMM outward to release it. Figure 1-10 2. [. . . ] 3. Removing a SIMM Move the SIMM to a 45° angle. Pull the SIMM out of the socket. Always remove SIMMs from the socket labeled SIMM-4, then SIMM-3, and so on. System Board 1-13 1. 4. 3 Reconfiguring the System You must enter Setup after installing or removing SIMMs to reconfigure the system. Follow these steps to reconfigure the system: 1. A memory error message appears, indicating that the total memory does not match the value stored in CMOS. A warning message appears indicating a wrong memory configuration. Press Atwice to exit and reboot the system. 2. 3. The system boots with the new memory configuration. 1. 5 IDE Fixed Disk Support The system board supports four IDE fixed disks, or any other IDE devices, through the two onboard PCI IDE interfaces. Follow the instructions in the housing installation manual on how to install a fixed disk in the system. Connect the cables according to the IDE fixed disk configuration in Table 1-4 Table 1-4 IDE Fixed Disk Configuration Master Fixed Disk 0 Fixed Disk 2 Slave Fixed Disk 1 Fixed Disk 3 IDE Connector Channel 1 Channel 2 1-14 User's Guide 1. 6 CPU Installation The system board comes with a zero-insertion force (ZIF) CPU socket for easy installation. Follow these steps to install a Pentium CPU: 1. Modify the memory configuration to agree with one of the options in Table 1-3. Check and connect the keyboard to the system unit. Replace the keyboard or contact your dealer.
