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.
