A hard disk icon does not appear on the MacOS desktop.
■
If the start-up hard disk is internal, restart your machine.
■
If the hard disk is external, verify that it is connected and terminated properly, and that it
has a unique SCSI ID. Make sure that there are no SCSI ID conßicts. See ÒUsing SCSI
devicesÓ on page 47 for information.
■
If the disk is your start-up disk, start up your computer from the Disk Tools ßoppy disk or
Power Computing MacOS CD-ROM. You can remove the internal drive from the startup
sequence (and force your system to boot from a ßoppy or the CD-ROM if you have it in
place) by holding down the
shift
,
option
,
command
, and
delete
keys (the
command
key
also called the
key) when you start up. Use the Disk First Aid program to check and
repair your disk. (See the Disk First Aid entry in Macintosh Guide for instructions.) If
repairing the disk does not solve the problem, reinstall the system software as described
in ÒReinstalling system softwareÓ on page 64.
You cannot read a ßoppy disk.
This can indicate a damaged disk or one that is not initialized.
■
If a ßoppy disk has never been used, it may not be initialized. See Macintosh Guide for
instructions on how to initialize disks.
■
If the disk is damaged, try using the Disk First Aid program to repair it. See Macintosh
Guide for instructions about using Disk First Aid.
The mouse pointer does not move when you move the mouse.
This can indicate a system software problem, a problem with your mouse, or a problem with
a program that you are running.
■
Turn off the computer and verify that the mouse is connected properly. See ÒConnecting
the mouse and keyboardÓ on page 6 for information.
■
Try using a different mouse or input device. If it works, there is a problem with the
original mouse.
■
Try using a different start-up diskÑthe Disk Tools ßoppy disk or the Power Computing
MacOS CD-ROM, for example. If the mouse works, there is a problem with the system
software on your normal start-up disk. Reinstall the system software as described in
ÒReinstalling system softwareÓ on page 64.
■
If the problem continues, you may be using an incompatible program. Verify that the
applications, system extensions, and control panels on your computer are compatible
with your system software.
No characters appear on the screen when you type.
■
Use the mouse pointer to click in the window in which you want to type. This ensures
that the program is active and that you have an insertion point for your text.
