software CD that came with the unit to get the correct version of
Mac OS 8.1 with the appropriate iMac enablers.)

both ends and make sure they are attached securely.

CD-ROM Vibration
CD-ROM vibration is
typically caused by
unbalanced CDs when
spinning at higher
speeds in the internal
CD-ROM drive. This
vibration may cause
the drive to have
difficulty reading the
CD.
1 Try using a known-good compact disc.
2 The iMac CD-ROM update v.10 has been posted to Apple SW
Updates web page. The CD Firmware Update reduces the
amount of vibration caused by certain CDs in the internal
CD-ROM drive. The iMac CD Firmware Update application
places new firmware on the CD-ROM drive to reduce the
amount of disc vibration.
