Dell ® Latitude® LM Documentation Update This document updates information contained in the online Dell Latitude LM User's Guide and the Dell Latitude LM Reference and Troubleshooting Guide. New Microprocessor Options The Dell Latitude LM is now available with a 166-megahertz (MHz) or 133-MHz Intel® Pentium® microprocessor with MMX™ technology. Current application programs not designed specifically for MMX technology should have a small improvement in performance when run on a system with a Pentium microprocessor with MMX technology. Software written specifically to take advantage of MMX technology (which will be labeled "Designed for Intel MMX") will have a greater improvement in performance, depending on the type of application program. The Pentium microprocessor with MMX technology has twice the internal cache memory (32 kilobytes [KB]) as the standard Pentium microprocessor. To see the technical specifications of the new microprocessors, search on "microprocessor specifications" in the online System User's Guide. The online guide is in the Dell Accessories folder or program group. New Memory Module Support The Dell Latitude LM now supports 32-megabyte (MB) memory modules. With the 8 MB of standard nonremovable memory on the system board and two 4-MB memory modules standard with every Latitude LM, the computer now supports a maximum of 72 MB of system memory. The following memory module combinations are possible: • 24 MB - Install two 8-MB memory modules. • 40 MB - Install two 16-MB memory modules. • 72 MB - Install two 32-MB memory modules. New Memory Specifications The Dell Latitude LM now supports extended-data out (EDO) memory. EDO memory technology improves performance over fast-page-mode technology by using a shorter page-mode cycle time while accessing data within a single page of memory. See the following table for the updated memory specifications. www.dell.com ® P/N 89180 Rev. A01 June 1997
