The Deskpro EN Series includes models based on Pentium II and Celeron processors. The
processor and heat sink is mounted as an assembly (Figure 2-9) in a slot (Slot 1) on the system
board. The Pentium II processor includes a microprocessor and a secondary (L2) cache contained
in a single edge connector (SEC) cartridge to which a heat sink is attached. The Celeron
processor includes a microprocessor mounted on a single edge processor package (SEPP) board.
On these systems the SEPP board of the Celeron processor is contained within a SEPP board
housing and heat sink.

The Pentium II and Celeron processors are backward-compatible with software written for the
Pentium MMX, Pentium Pro, Pentium, and x86 microprocessors. The integrated microprocessor
provides performance enhancements for multi-byte and floating-point processing.
