Replacing the Option Card Connector Board
If you removed the option card connector board to access any
system components, refer to the illustration on page 4-14 as you
follow these steps:
1.
Position the board above its slot and then firmly push it
straight in.
2.
Secure the board to the power supply with its retaining screw.
Now you can re-install any option cards you removed. See
page 4-14 for instructions.
Installing a New Processor Chip
You can enhance your 25 MHz or 33 MHz system’s
performance by installing an Intel OverDrive processor.
Alternatively, for the 25 MHz system, you can install a
487SX microprocessor with a built-in math coprocessor.
An OverDrive processor is a CPU chip which doubles the
internal processing speed of the microprocessor and includes a
built-in math coprocessor. A math coprocessor is an optional
microprocessor for 486SX systems that allows them to perform
some mathematical functions faster.
