The 686IPK is an Intel Pentium

II processor based system board using
Intel’s high performance 233MHz Pentium ® II processor with 512KB ex-
ternal L2 cache, 233MHz Pentium ® II processor with 256KB external L2
cache or 266MHz Pentium ® II processor with 512KB external L2 cache.
The 686IPK supports processor fan “failure detection” function that
monitors the status of the processor fan. It detects any irregularity in
processor fan RPM (Rotation Per Minute) and alerts you to attend to
any problem that may damage your system. The “failure detection” cir-
cuit requires a processor fan that operates at greater than 3600 RPM.
The 686IPK is equipped with a switching voltage regulator that auto-
matically detects 1.8V to 3.5V. The VID (Voltage Identifications) code
found in a processor allows the 686IPK to detect and adjust to the re-
quired voltage.
The 686IPK system board can support 8MB to 512MB of system
memory. It is equipped with 4 SIMM sockets allowing you to install x32
or x36 EDO or fast page mode SIMMs. The x36 SIMM supports parity
checking which informs the user of memory failure and prevents error
accumulation.
The 686IPK system board is designed to fit into an ATX form factor
case. Using an ATX power supply, you can either shut down your com-
puter by pressing the Power button located on the front bezel of your
computer or by executing the Shut Down command under the
Windows

95 operating system. Your system will enter the “soft power
off” state. With a modem installed, you can power on your system to
remotely transmit or access data. An ATX power supply also provides
adequate airflow throughout the chassis to prevent overheating the pro-
cessor.
