or stress the circuit board. Keep the board in its static-proof packing until
you are ready to install it. Follow the static guidelines given at the
beginning of Chapter 2.
Features
The key features of this mainboard are the wide range of processors that
can be installed, and the support for both AT and ATX power supplies.
Wide Choice of Processors
This mainboard provides an excellent platform for an inexpensive value
PC that is internet-ready thanks to the fax/modem module. The socket-
370 can be installed with a PGA Celeron or FC-PGA Coppermine
processor. The PGA Celeron has 32k of internal cache memory, 128K of
external cache memory, and operates over a 66 MHz system bus. The
PGA Celeron ships with clock speeds running from 300 MHz through to
533 MHz. The FC-PGA Coppermine operates over a 100 MHz system
bus. The FC-PGA Coppermine ships with clock speeds running from 500
MHz through to 750 MHz.
The PGA Celeron and FC-PGA Coppermine processors are the ideal
choice for an entry-level PC.
For better performance, the KOB 693 DCS can be installed with a slot1
processor. The SEPP (Single Edge Processor Package) Celeron is the
least expensive slot-1 processor. It has 32K of internal cache memory,
128K of external cache memory (except for older versions), and
operates over a 66 MHz system bus. SEPP Celerons ship with clock
speeds ranging from 266 MHz through to 533 MHz.
For higher-performance business-class computing, the slot1 can be
installed with a Pentium-II or Pentium-III processor cartridge. The
Pentium-II and Pentium-III have 32K of internal cache memory and 512K
of external cache memory. They operate over a 100 MHz system bus
(except for older Pentium II versions). The Pentium-III includes new
instructions that are designed to enhance multimedia/internet computing
by providing rapid encoding and decoding of the compressed audio and
video files which are pervasive in the internet environment. The Pentium-
II ships with clock speeds running from 233 MHz through to 450 MHz.
The Pentium-III ships with clock speeds of 450 MHz, up to 750 MHz, and
higher.
