2. Introduction
The key feature of the M81-X series motherboard is the dual Processor socket which allow
you to install any of the Slot1 Processor (including Pentium II/III and SEPP Celeron) and
PPGA370 Processor.
The Pentium II/III Processor which include 32K of internal level-1 cache memory and 512K of
external level-2 cache memory.
Pentium II Processor can run a 66MHz system bus and operate at clock speed from 233MHz
up to 333MHz.
Pentium II/III Processor also can run a 100MHz system bus and operate at clock speed
from 350MHz up to 600MHz.
The SEPP Celeron Processor which include 32K of level-1 cache memory and 128K of level-
2 cache memory. It can run a 66/100MHz system bus and operate at clock speeds up to
500MHz. (Note : Celeron 266/300 Processor do not have feature of level-2 cache memory on
die).
The PPGA370 Celeron Processor is square plastic package and install in a Zero Insertion
Force (ZIF) socket called a PGA370 Socket.
The new Celeron Processor are close to Pentium II performance because they include a
level-2 cache memory of 128K. However, they operate at a 66/100MHz system bus and
operate at clock speeds up to 500MHz.
You can configure the motherboard for any of supported Processor System Bus Frequency
using the BIOS setup utility. It is not necessary to set switches or jumpers. Also it can Auto-
Detect Processor clock speeds of the Slot1 SEEP Celeron and PPGA370 Celeron Processor.
This motherboard allows complete flexibility. You can choose the high performance Slot1
Pentium II/III Processor or the inexpensive PPGA370 Celeron Processor according to the
system requirements and price/performance comparison of the two kinds of Processor. For
performance and upgrade required, we recommend you must install PC-100 compliant DIMM
modules that operates at 100MHz.
M81-X series motherboard provides four 32-bit PCI slots and an AMR slot, also has two support
Ultra DMA33/66 PCI IDE channel and floppy disk drive peripherals interface.
In addition to superior hardware capabilities, features like Plug and Play, Soft-off, ACPI function,
Keyboard Power-On, Wakeup by Ring/LAN, fan off in sleeping state and BIOS upgraded are
provided on M81-X series platform.
