Cautions

• You cannot plug the iPod shuffle directly into the iMac's USB port - it will not fit. It will not charge if plugged into a keyboard USB port or an unpowered USB hub. To charge it while using it with your iMac, you must us a USB extension cable, powered USB hub, iPod shuffle dock, or a USB power adapter.
• Update Firmware Before Installing Jaguar!, Geoff Duncan, TidBITS, 2002.10.28. If your firmware isn't at version 4.1.9, you need to boot into OS 9.1 and install it before attempting to install Jaguar (OS X 10.3) on your slot-loading CD-ROM or DVD iMac.
• You must have the keyboard plugged directly into an iMac USB port to boot with the power key; it will not work if the keyboard is attached to a hub.
• You cannot boot the iMac from an external USB drive.
• The iMac loads the MacOS Toolbox into RAM, unlike other Macs which use it from ROM. You lose the use of 3 MB of memory but gain faster performance.
