Do not remove a component from its antistatic packaging until you are ready to install it. Wear a wrist grounding strap before handling electronic components. Wrist grounding straps are available at most electronic component stores. Do not attempt the procedures described in the following sections unless you are a qualified technician. System Board 1-11 1. 4 Memory Upgrade The system board comes with four 72-pin SIMM sockets that support 4-MB and 16-MB single-density SIMMs and 8-MB and 32-MB doubledensity SIMMs. [. . . ] Reverse the orientation of the SIMM. 2. Gently push the SIMM to a vertical position until the pegs of the socket slip 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. 1 2 Peg Pin 1 Indicator (curved edge) Hole Figure 1-8 Installing a SIMM 1-14 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. Pull the SIMM out of the socket. Holding Clip 1 3 2 Figure 1-9 Removing a SIMM Always remove SIMMs from the socket labeled SIMM-4, then SIMM-3, and so on. System Board 1-15 1. 4. 3 SIMM Type Selection When selecting SIMMs to install, make sure to take note of the height limitations of the slot board installed in the system. Table 1-6 shows the SIMM height limitations for the different slot boards. Table 1-6 SIMM Height Limitations Slot Board SIMM Height Limit 23. 3 mm 28. 8 mm 21. 8 mm 26. 8 mm Aspire Desktop and AcerBasic Aspire Minitower ID2PN and ID2M IDABN 1-16 User's Guide 1. 4. 4 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 Press appears indicating an incorrect memory configuration. Press twice to exit and reboot the system. 2. 3. The system boots with the new memory configuration. 1. 5 IDE Hard Disk Support The system board supports four IDE hard disks, or any other IDE devices, through the two onboard PCI IDE interfaces. A message of this type normally appears during the power-on self-test, before the operating system prompt appears. Table 1-9 lists the system error messages. 1-26 User's Guide Table 1-9 System Error Messages Message Action Replace the RTC chip or contact your dealer. Check the RTC chip and the necessary jumper. If the battery is still good, run Setup. Run Setup Check and connect the control cable to the diskette controller. Run Setup and select the proper drive type. Run Setup and select the proper drive type. Modify the memory configuration to agree with one of the options in Tables 1-3 or 1-4. Check and connect the keyboard to the system unit. Replace the keyboard or contact your dealer.

An equipment malfunction is more likely to cause a fatal error, i. e. , an error that causes complete system failure. Here are some corrective measures for error conditions: 1. [. . . ]
