Upgrading
Chapter 9
Upgrading the processor
Your computer is supplied with an Intel486 or IntelDX4
processor.
The ZIF (zero insertion force) processor socket on the
motherboard is designed to accept a variety of Intel
processors. You can upgrade your processor by replacing it
with one of higher performance.
Before purchasing a new processor you must check that its
operating voltage is compatible with your system. Intel486
systems accept processors operating at 5 volts, IntelDX4
systems operate at 3.3 volts.
You must also find out the external clock speed of the new
processor. This must be either 25 or 33 megahertz (MHz).
Check carefully: the external clock speed is often only a
fraction of the internal clock speed, which is usually the one
advertised.
The following table shows the possible upgrade paths for
Intel486 (5 volt) and IntelDX4 (3.3 volt) systems:
Intel486 systems IntelDX4 systems

Intel486 DX2-66 IntelDX4-100
Intel486 DX2-50
