If you need to change any jumper settings, follow these steps:
1. Remove any option cards that may be blocking your access
to the jumpers. See page 5-15 for instructions.
2. Change the jumper settings as necessary.
3. Replace any option cards you removed. See “Installing an
Option Card,” below.
4. Follow the instructions on page 5-30 to replace the
computer’s cover.
Installing an Option Card
Your computer has four standard option slots: three 16-bit slots
and one B-bit access slot. Each slot can accommodate an option
card. You can buy option cards from authorized Epson dealers as
well as other vendors.
This section explains how to install option cards in your
computer. Later on, you may need to remove an option card to
access jumpers, memory modules, or a math coprocessor. If so,
see “Removing an Option Card” on page 5-15 for instructions.
Note
After you install or remove an option card, see “Post-
installation Setup” at the end of this chapter to configure
your computer to operate with or without the option card.
