c computer systems are high-speed personal computers that
include an Intel
®
Celeron processor with MMX technology. These systems incor-
porate a high-performance Peripheral Component Interconnect (PCI) design, allowing
a wide range of initial configurations and upgrade possibilities.
This chapter provides information about the following:

Your Dell
computer offers the following hardware features:
An Intel Celeron microprocessor with MMX technology.
The
Main
screen of the system setup program lists the speed of your systems
processor. For information on accessing this program, refer to Appendix B, Sys-
tem Setup Program.
Cache memory that enhances the speed of many microprocessor operations by
storing the most-recently accessed contents of system memory:
The L1 cache consists of an integrated 32-KB instruction and data cache.
The L2 cache consists of 128 KB of synchronous dynamic random-access
memory (SDRAM) that resides in the processor core. The L2 cache runs at
the processors internal speed.
Memory that can be increased up to 512 megabytes (MB) by installing 32-,
64-, 128- or 256-MB SDRAM dual in-line memory modules (DIMMs) in the two
DIMM sockets on the system board.
NOTE: The system memory value reported by the operating system is 1 or 2 MB less
than the memory installed because that memory is reserved for video functions. For
example, if the computer has 32 MB of system memory, the operating system may
report 30 or 31 MB.
