2. From the table below, and the label on your upgrade
processor, or its packaging decide which system clock
speed you need to select.
JP7 position
1-2
2-3
If you have installed an OverDrive processor you should
set the system clock speed to match the external interface
speed of the processor. OverDrive processors use
IntelÕs clock doubling technology and the processor
runs at twice the speed of its interface to the
motherboard.
The labelling on the OverDrive processor or its
packaging should make it clear what its external
interface speed is.
5. Having decided which selection you require check the
position of JP7, and if necessary move it to the appropriate
position.
6. You should by now have: identified the processor socket,
removed the processor, installed the new processor,
and set the system clock speed. If you are uncertain
about having completed any of these steps, go back to
the beginning and check the steps you carried out
against the installation instructions.
7. Once you are satisfied that you have installed the
upgrade and configured the system correctly,
reassemble the system.
