Here's what to do:
1. Make sure the telephone cord is securely plugged into the telephone outlet in
the wall and into the system unit. Your Read Me First booklet shows how the
cord should be connected.
2. Make sure the telephone line works by plugging a working telephone into the
same telephone outlet that the computer was plugged into. Then make sure
you can place a call.
3. Make sure you are calling the correct number, and that you are using the
correct communications settings. For additional help, see the user's guide for
your communications software.
4. Make sure no one is using the telephone while you are communicating with
another computer.
5. If some communications programs work but others do not, there may be a
configuration problem. For additional help, see the user's guide for your
communications software.
6. Make sure your modem cord is connected to an analog telephone line. For
additional help, see "Modem information" on page 23.
7. Make sure the modem adapter card is installed correctly. For instructions on
installing adapter cards, see "Working with your system unit" on page 81.
1. Choose Start Options from the Configuration/Setup Utility main menu, and
make sure that Startup devices are set correctly.
2. Make sure the drive power and signal cables are securely attached to the back
of the hard disk drive. For instructions on working in the system unit, see
page 81.
3. Insert the Recovery diskette into drive A, and press F1. The Recovery diskette
is the one that you were instructed to create in First Steps. Follow the
instructions on your screen to restore the operating system files to your
computer's hard disk.
4. If you are not able to restore the operating system files to your computer's
hard disk or if you did not make a Recovery diskette, check your Services and
Support Guide for information on obtaining service.
