Question 1: Which computers work with the iMac CD Update 2.0?

Answer : iMac CD Update 2.0 will work on most 233 MHz, 266 MHz, and 333 MHz iMac computers.

Question 2 : What improvements does this update include?

Answer : iMac CD Update 2.0 places a new version of firmware on the CD-ROM drive to reduce disc vibration caused by unbalanced CDs. The update also corrects a ten-second pause that can occur intermittently on some iMac computers.

Question 3 : Should this update be installed on all iMac computers?

Answer : If your iMac has vibration noise when using certain unbalanced discs, or if your iMac intermittently pauses for ten seconds during normal use, then the update should be installed. If your iMac is not experiencing either of these issues, it is not necessary to install the update.

Question 4 : Does iMac CD Update 2.0 replace the iMac CD Update 1.0?

Answer : Yes, iMac CD Update 2.0 replaces iMac CD Update 1.0. This update incorporates the firmware that was part of the iMac CD Update 1.0. If you have already used 1.0 to update your CD drive, then updating to 2.0 is unnecessary.

Question 5 : iMac CD Update 2.0 reports the "Update is NOT necessary", and the "Device has already been updated."

Answer : There are two reasons why this message occurs.

• A previous version of the update, iMac CD Update 1.0, has already been installed on the iMac, and that is all that is required for your CD-ROM drive.
• The appropriate firmware update has already been installed during manufacturing.

Question 6 : Does iMac CD Update 2.0 make any changes to the iMac if the updater reports that the "Update is NOT necessary"?

Answer : If iMac CD Update 2.0 determines the latest firmware is already installed on the CD-ROM drive, a dialog box appears indicating that the update is unnecessary. Clicking OK will quit the updater, leaving the iMac and CD-ROM drive untouched.

Question 7 : When I ran iMac CD Update 2.0 on my iMac, I got an error message that the update failed due to a "Program or drive configuration Error." What does this mean?

Answer : A "Program or drive configuration Error" indicates that you are attempting to update a CD-ROM drive that does not work with iMac CD Update 2.0.
