Diskette Drive Problems
Check the following to see the possible cause and solution.
„
Diskette won’t load.
Check that the diskette is being loaded correctly.
Check that the system and monitor power lamps are on and the power-on
screen appears.
Check that the diskette is formatted. If not, format it.
Check that the diskette size is 1.44 MB.
If the diskette drive busy lamp does not light when loading the diskette,
try a different diskette. If this loads, the problem is in the software.
„
Non-System Disk or Disk Error message displayed.
If trying to boot from the diskette drive, insert a diskette with system files
into drive A.
If a bootable diskette does not boot, use the Setup utility to verify that the
initial boot parameter is set to diskette drive A and not a hard drive.
CD-ROM Drive Problems
Check the following problems to see the possible cause and solution.
„
The system does not see the CD-ROM drive.
The drive designation is wrong and should be changed. The drive
designation for the CD-ROM drive depends upon the storage device
configuration in the system. To find out what drive designation letter is
assigned to the CD-ROM drive, double click
My Computer on the
Windows 95 or Windows NT 4.0 desktop. The drive designation is below
the CD-ROM drive icon.
As an alternative, open Windows Explorer and scroll down the list of
folders until you locate the CD-ROM drive icon. The drive designation is
beside the icon.
„
The CD-ROM drive is not reading a disc.
Check that the disc is inserted in the CD tray with the printed label side
up.
Check that the disc is a data disc, not a music disc.
Try a different CD to see if the problem is limited to one CD.
„
The CD does not eject due to a power failure or software error.
Turn off the system and use the CD-ROM emergency eject feature. Insert
the pointed end of a paper clip into the eject hole. Press inward on the
clip to open the door.
