Summary

The following instructions detail a "Dual Boot" install of Mac OS (7.6.x or 8.x) and Rhapsody (Apple Rhapsody DR2 GM). These instructions assume you have (at minimum) a 1.0Gb (1024Mb / 1048576kb) HD wholly available for this installation. You will install a minimum sized Mac OS partition (enough for simple tasks, but with full features available), and a 'maximal' Rhapsody partition. Apple Rhapsody DR2 GM requires a standard Apple ADB keyboard and does not support "special" ADB devices (only standard Apple Mice/Keyboards).

Note:
THIS WILL DESTROY ALL DATA ON YOUR DRIVE

Instructions


1) Zap PRAM

From a Cold Boot, hold down the CMD-OPT-'P'-'R' keys until the machine cycles through the boot chimes at least twice. You will need to press and hold the keys within 1-3 seconds of power-up.

 

2) Boot off Mac OS CD

Insert a Mac OS 8.x or Mac OS 7.6.x CD into the drive, and Warm Reboot the machine. As soon as you hear the boot chimes, hold down the "c" key. Wait for the Smiley-Mac, and then release the "c" key.

 

3) Partition the Drive

Please note that these partition sizes are only valid if you have a 1.0GB drive; if your drive is larger, please size the partitions relative to the size of your drive (e.g., on a 2GB drive, I use a 1500MB partition for Rhapsody).

Launch "Drive Setup" (found in :Utilities), and select the SCSI ID, or ATA if using an IDE based machine, for the destination drive (internal HD is usually SCSI ID 0 for 604 based Power Macintosh machines and ATA0 for G3 series machines). Select the drive to be installed on and click "Initialize", then select "Custom Setup", click on "Partitioning Scheme" and select "2 Partitions". You now have 2 equal sized partitions, named "untitled", and "untitled2", both 500MB each, on the 1.0GB drive. If you wish to have 2 equally sized partitions, continue on to "Install Mac OS", otherwise click on "untitled" and type "790" in the "size" dialog and then click on "untitled2" and type "250" in the "size dialog. This will leave 2MB free on a 1.0GB drive for future Driver Patches. Click on "Ok", and then "Initialize".

You should now have a drive with two partitions (one 250Mb and the other 790MB). Quit Apple Drive Setup and follow the boot instructions from section <4>.

 

4) Install Mac OS

On the CD, locate and double click on "Install Mac OS". Select your destination disk (this should be "untitled2"), verify that the Available disk space is "247MB" +/- and click "Select", continue to the "Install Software" menu and de-select everything except Mac OS, (Mac OS Updater) and MacLink Plus. Select "Start" and proceed with the installation. When the installation has completed, quit the installer and restart the machine (you may eject the Mac OS 7.6.x or 8.x CD while the machine is rebooting).

 

5) Prepare to Install Rhapsody

Insert the Apple Rhapsody DR2 GM CD into the CD drive. Copy the "MultiBooter" folder from the CD onto the newly installed Mac OS partition (the one with the Mac OS on it, called "untitled2" unless you renamed it).

 

6) Boot Rhapsody CD

Reboot the machine, holding down the "c" key until you see the smiley-mac. Double-click the "Install Rhapsody DR2" application and follow the menus to select the appropriate device and partition named "untitled". Be sure to select the correct drive ID if you have multiple hard drives connected to your Macintosh, and click "Ok". The Rhapsody Installer will then prompt you to restart your Macintosh. Click on "Restart". Your Macintosh will restart under Rhapsody DR2 and continue the install process.

 

7) Rhapsody Installation

Once the Rhapsody boot cycle has completed, the installer will install the Rhapsody base OS. Once this is done your Macintosh will restart and you will be presented with the 2nd installation menu. You can safely proceed with the default installation settings (install everything). You will be prompted to reboot one more time after Rhapsody has installed all of the packages you have selected for install.

 

8) Final Configuration

Follow the steps as presented by the Rhapsody Setup Assistant.

You're now fully configured for Dual Boot. To boot into Mac OS, restart with the "m" key down; otherwise Rhapsody will be the default OS at boot time. In the event that you've zapped your PRAM, and your machine now only boots into the Mac OS, Use the application "MultiBooter", to select your Rhapsody partition, as the default partition to boot from, save, quit and then restart.

 

9) Optional Items

The default installation of Rhapsody leaves some security holes open, and is not appropriate for a "hostile" computing environment. Please see "Rhapsody Security" for more information.
