[. . . ] 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. 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. An incorrect configuration is a major cause of power-on error messages, especially for a new system. Check that the jumpers on the system board and any expansion boards are set correctly. 2. 1-18 Altos 9100B System Guide 3. If you cannot access a new disk, it may be because your disk is not properly formatted. Format the disk first using the FDISK and FORMAT commands. Check that all connectors and boards are securely plugged in. 4. If you go through the corrective steps above and still receive an error message, the cause may be an equipment malfunction. If you are sure that your configuration values are correct and your battery is in good condition, the problem may lie in a damaged or defective chip. In either case, contact an authorized service center for assistance. BIOS Utility 1-19 Chapter 2 CPU Board The CPU board carries two sockets to support a powerful dual-CPU configuration. The sockets accommodate the new Intel Pentium II CPU running at 266/66, 300/66, 333/66, 350/100, 400/100, or future Intel Pentium II processors and higher. The board comes with four DRAM banks composed of four 168-pin dual-inline memory module (DIMM) sockets that accommodate Synchronous DRAM (SDRAM) DIMMs. The system's CPU board supports multiple-bit error detection and single-bit error correction through the ECC/parity feature.

Memory timing setting of 66 MHz are defined under unbuffered DIMM specifications while 100 MHz are defined under Intel PC-100 SDRAM and PC registered DIMM specifications. Do not use both 66 MHz (unbuffered) and 100 MHz (registered) SDRAM together. This might cause your system to malfunction. The sockets support SDRAM DIMMs for a total of 1024-MB (unbuffered) system memory using 128-MB DIMMs. Memory Configurations Bank 1 Bank 2 Bank 3 Bank 4 Total Memory 32 MB 32 MB 32 MB 32 MB 64 MB 64 MB 64 MB 64 MB 128 MB 128 MB 128 MB 64 MB 64 MB 64 MB 64 MB 64 MB 64 MB 32 MB 32 MB 32 MB 32 MB 32 MB 32 MB 32 MB 64 MB 96 MB 128 MB 64 MB 128 MB 192 MB 256 MB 128 MB 256 MB 2-4 Altos 9100B System Guide Bank 1 Bank 2 Bank 3 Bank 4 Total Memory 128 MB 128 MB 256 MB 256 MB 256 MB 256 MB 128 MB 128 MB 128 MB 128 MB 128 MB 384 MB 512 MB 256 MB 256 MB 256 MB 256 MB 256 MB 256 MB 256 MB 512 MB 768 MB 1024 MB The above configurations are only some of the available memory combinations. When upgrading memory, simply install DIMMs into any of the empty sockets. Installing a DIMM To install a DIMM, align it with the socket and press it down until the holding clips secure the DIMM in place. The DIMM socket is slotted to ensure proper installation. If you slip in a DIMM but it does not completely fit, you may have inserted it the wrong way. Reverse the orientation of the DIMM. CPU Board 2-5 Removing a DIMM To remove a DIMM, press the holding clips on both sides of the socket outward to release the DIMM. Place your forefingers on the top of the DIMM before you press the holding clips to gently disengage the DIMM from the socket. 2-6 Altos 9100B System Guide Reconfiguring the System You must enter Setup after installing or removing DIMMs 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. [. . . ] As long as the internal battery remains good (approximately seven years) and connected, the clock continues to keep the date and time accurately even when the power is off.
