ew System Features
Additional system features include:
Now available with a 166-MHz Intel® Pentium® microprocessor with
•
MMX™ technology in the Dell Latitude LM M166ST, which has the same
features as other models of the computer.
Support for a maximum of 72 MB of system memory by installing a
•
matched pair of 32-MB memory modules in the memory upgrade sockets on
the main board. (The standard minimum configuration is now 8 MB of nonremovable memory on the main board and two 4-MB memory modules in
the memory upgrade sockets.)
The Pentium microprocessor with MMX technology has twice the internal
•
cache memory (32 KB) as the standard Pentium microprocessor.
A NeoMagic 2093 video controller for a video subsystem that includes
•
1.1 MB of video memory.
6X or 10X CD-ROM drives.
•
Your computer may not appear exactly as shown in some of the figures in
