Do not remove a component from its antistatic packaging until you are ready to install it. 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. 1-8 User's Guide 1. 4 Memory Upgrade The system board comes with four 72-pin SIMM sockets that support 4-MB and 16-MB single-density SIMMs as well as 8-MB and 32-MB double-density SIMMs. When using 32-MB SIMMs, the sockets support a maximum system memory of 128 MB. Table 1-3 lists the possible memory configurations. 1. 4. 1 Rules for Adding Memory · · · Use only one type of SIMM in a given bank. You may combine different types of SIMMs for a memory configuration as long as the SIMMs in each bank are of the same type. For example, for a total memory of 8 MB, install two 4-MB SIMMs into the sockets marked S5 and S4 (bank 0) or S3 and S2 (bank 1). You can not use an 8-MB SIMM alone for an 8-MB memory.

These messages typically occur after you boot the operating system or when you run your applications. If you receive this type of message, consult your application or operating system manual for help. 1. 8. 2 System Error Messages A system error message indicates a problem with the computer itself. A message of this type normally appears during the power-on selftest, before the operating system prompt appears. Table 1-5 lists the system error messages. 1-16 User's Guide Table 1-5 System Error Messages Message Action Replace the RTC chip or contact your dealer.

An equipment malfunction is more likely to cause a fatal error, i. e. , an error that causes complete system failure. You must know the correct configuration values for your system before you enter Setup, which is why you should write them down when the system is correctly configured. [. . . ]
