610 systems are high-speed, upgradable workstations designed
around Intel
®
Pentium
®
II Xeon
™
processors. These DeIl
®
systems support the high-
performance Peripheral Component Interconnect (PCI) bus and the accelerated
graphics port (AGP) bus. Each system also has an Industry-Standard Architecture (ISA)
design with one ISA slot that allows you to configure the computer system to your ini-
tial requirements and then upgrade it as necessary.
This chapter describes the major hardware and software features of the system and
provides information you will need to reinstall the operating system, if necessary. It
also provides information about the indicators and controls on the computer’s front
panel and discusses connecting external devices to the computer.

The system offers the following features:
‡
An Intel Pentium II Xeon processor. The following processor option is available:
— Single or dual Intel Pentium II Xeon processor(s) with an internal speed of
400 MHz and an external speed of 100 MHz
The Intel Pentium II Xeon processor includes MMX
™
technology designed to han-
dle complex multimedia and communications software. This processor
incorporates new instructions and data types as well as a technique called single
instruction, multiple data (SIMD). SIMD allows the processor to process multiple
data elements in parallel, thereby improving system performance when you are
running application programs written to take advantage of MMX technology.
The Intel Pentium II Xeon processor has a 16-kilobyte (KB) internal data cache and
a 16-KB internal instruction cache, an internal math coprocessor, and other
advanced internal logic.
‡
A secondary cache of 512 KB or 1 megabyte (MB) of static random-access mem-
ory (SRAM) integrated in the Slot 2 single-edge contact (Slot 2 SEC) cartridge.
The secondary cache also provides error checking and correction (ECC) capability.
‡
Dual-processor capability. The system allows the installation of a second Slot 2
SEC cartridge (operating at the same frequency as the installed processor), which
can be purchased as a kit from Dell. Dual processing improves performance
