Features
The key feature of this mainboard is the dual processor sockets which
allow you to install any of the Pentium-III and Pentium-II processors
including Slot1 cartridges SEPP Celerons and PPGA Celerons. In
addition, this is a full-sized ATX mainboard with a full set of expansion
slots for maximum development potential.
Support for Pentium-III/Pentium-II Cartridges or PPGA Celeron
The principal feature of this mainboard is that it can support three kinds
of processors: Pentium-III cartridges, Pentium-II cartridges and SEPP or
PPGA Celerons. Pentium-III cartridges feature 512K of level-2 cache
memory with improved instructions to handle 3D audio and video.
Speech recognition, MPEG2 motion picture encoding/decoding, and
TCP/IP internet connections. The Pentium-III runs over a 100 MHz
system bus and operate at clock speeds from 450 MHz up to 550 MHz
or more.
The Pentium-II cartridges are very powerful processors which include
32K of internal level-1 cache memory and 512K of external level-2 cache
memory. The first generation of Pentium-II cartridges ran over a 66 MHz
system bus, but current Pentium-II cartridges run over a 100 MHz
system bus and operate at clock speeds from 350 MHz up to 450 MHz
or more. The slot-1 processor can also be used by the SEPP Celeron
processors which can operate over a 66/100 MHz system bus and
operate at clock speeds up to 466 MHz.
The new generation PPGA Celeron processors ship in the familiar
square plastic package, and they install in a Zero Insertion Force (ZIF)
socket called a Socket-370. The new Celeron processors are close to
Pentium-II performance because they include a level-2 cache memory of
128K. However, they operate at a 66/100 MHz system bus and they
currently ship a clock speeds of 466 MHz.
System assemblers can install either a Pentium-III or Pentium-II
cartridge or the SEPP Celeron in the slot-1 processor slot. Alternatively,
they can install a second generation PPGA Celeron in the Socket-370
processor socket. Assemblers can choose the processor they need to
meet performance or price targets. You can configure the system for any
of the supported processor clock speeds using the BIOS setup utility. It
is not necessary to set switches or jumpers.
Choice of Memory Options
The board has three DIMM slots for the installation of 168-pin, 3.3V
standard or registered SDRAM (Synchronous Dynamic Random Access
Memory) memory modules. The system supports memory that has built-
