HARDWARE CONFIGURATION

HOT-683 mainboard provides a 370-pin ZIF Socket370 for Intel PPGA Celeron CPU. The
CPU that came with the mainboard should have a fan attached to it to prevent overheating. If
this is not the case then purchase a fan before you turn on your system.

To install a CPU, first turn off your system and remove its cover. Locate the ZIF Socket370
and open it by first pulling the lever sideways away from the socket then upwards to a 90­degree right angle. Insert the CPU with the correct orientation as shown.(Figure 2-1) Use
the notched corner of the CPU as your guide. The notched corner should point towards the
end of the lever. Notice that there are two blank area where one hole is missing from that
corner of the square array of pin holesr. Because the CPU has a corner pin for two of the
four corner, the CPU will only fit in the one orientationn, hold down on the CPU and close
the socket’s lever.

Figure 2-1

Then you should have a CPU fan that
will cover the face of the CPU. Apply
thermal jelly to the CPU metallic top and
then install the fan onto the CPU. (Figure

If you have equipped your system with a PCI controller, changing this allows you to
specify which slot has the controller and which PCI interrupt (A, B, C or D) is associ­ated with the connected hard drives.

Remember that this setting refers to the hard disk drive itself, rather than individual
partitions. Since each IDE controller supports two separate hard disk drives, you can
select the INT# for each. Again, you will note that the primary has a lower interrupt
than the secondary as described in "Slot x Using INT#" above.

Selecting "PCI Auto" allows the system to automatically determine how your IDE disk
system is configured.
