Personal Computer User Manual

Many application programs (such as word processors) must

be set up properly before they can use a printer. Check your

program manual to see what customization is required.

Try running the Parallel Port (Printer Interface) Check if

you have a parallel printer, or the Serial Port (RS-232C)

Check if you have a serial printer. Appendix C describes

these diagnostics checks. If the diagnostics test indicates an

error, contact the place where you bought the printer.

Option Card Problems

If you install an option card and it is not functioning properly,

check the following:

Is the option card installed correctly? Check the installation

procedure described in Chapter 5 and also see the

instructions that come with the option card. The most

common problem with option cards is a loose connection.

Make sure the option card is well-seated in its slot.

Did you set the necessary DIP switches or jumpers on the

option card? See your option card manual for instructions.

Did you run the Setup program to redefine your computer’s

configuration after installing the card? See Chapter 2.

If you installed a memory card in your computer, see “Post-

installation Setup for Memory Cards” in Chapter 5.

If you installed a hard disk drive that has its controller on

an option card, you may need to change the position of

jumper J3 on the main system board. See “Changing Jumper

Settings” in Chapter 5. Also, if your Equity 386SX came

with a hard disk drive that you are no longer using be sure

the cable leading from that drive to the main system board

is disconnected.
