To boot a PowerMac (or an iMac, iBook, eMac, etc...) from an USB stick or drive, if you have a G5 or late G4 model, first refer to the boot from CD guide and if it does not work, then follow these instructions: 1. Plug your USB stick or drive in an USB port 2. Power the computer on (or restart it if it's already running) and immediately... 3. ...hold down those 4 keys together: [ CMD + OPT/ALT + O + F ] until you see the white Open Firmware screen similar to this: 4. Then at the Open Firmware command prompt, type this and press ENTER: boot usb0/disk@1:,:tbxi (Please make sure that there are 2 backslashes before :tbxi just in case this page contents gets screwed up in the future) Note: You may have to change usb0 for usb1 depending on which port you plugged your USB stick in. If it still doesn't work, you can try this command: boot ud:,:tbxi Note 2: If you want to boot a non-Macintosh partition, say for instance a PPC Linux distribution, then change tbxi for yaboot Note 3: If you get a CAN'T OPEN error, it means that you forgot to plug in your USB stick BEFORE powering on the computer, so turn the Mac off and start over from step #1. |
The iMac G4 was released in 2002. It encompasses a flat panel monitor, an adjustable arm, and a dome-like base. The iMac G4 was nicknamed the 'iLamp' because it resembled the pixar lamp. Compared to the iMac G3, the iMac G4 had better screen quality. In addition, the iMac G4 utilized space better than the iMac G3. The iMac G3 was the first model of the iMac line of personal computers made by Apple Inc. (formerly Apple Computer, Inc.). The iMac G3, based on the Columbus architecture is an all-in-one personal computer, encompassing both the monitor and the computer in a single enclosure. Originally released in striking 'bondi blue' and later a range of other brightly colored, translucent plastic casings.

The iMac G4 featured an LCD mounted on an adjustable arm above a hemisphere containing a full-size, tray-loading optical drive and a fourth-generation PowerPC G4 74xx-series processor. The internals such as the hard drive and motherboard were placed in the 'dome' instead of the LCD panel as it would be too heavy. At launch in January 2002, the iMac G4 came in three flavors: a low-end model for $1299 that included a 700MHz G4 PowerPC processor, 128MB RAM, a 40GB hard drive, and a CD-RW drive; a mid-range.
