Upgrading The Processor - Mitsubishi Electric apricot MS660 Owner's Handbook Manual

Reconfiguring the system

Upgrading the processor

Removing the old processor
The first time you turn on the computer after adding or removing
SIMMs the memory change will be automatically detected by the
power-on self-test (POST). All you have to do is confirm the new
configuration in the BIOS Setup utility (refer to 'System BIOS and
Setup' for more information).
If an error message occurs check that:
♦
You have installed a configuration supported in the list above.
♦
You have correctly fitted the SIMMs in their slots.
♦
The SIMMs are of the correct type.
It may be necessary to refit the original memory SIMMs to check if
there is a problem with your new SIMMs. If in any doubt contact
your supplier.
You may wish to upgrade your processor by replacing it with one of
higher performance, but check with your supplier or Apricot dealer
as to the type and availability of replacement processors. The most
suitable for this system is a processor selected from the same range
as the currently fitted one.
The system supports a range of external clock speeds of 50, 60 and
66 megahertz (MHz). The clock speed is set by adjusting jumpers
on the motherboard. Note that the external clock speed is lower
than the processor's internal clock speed, which is usually the one
advertised. The ratio of the internal and external clock speeds is
known as the 'processor clock multiple'.
1. Turn off the computer and unplug all power cords. Take
suitable anti-static precautions and remove the system main
side panel and top panel. Detailed instructions for this are
given in chapter 1.
