I agree with Lee and George, using a second hard drive is definitely the way to go. In this manner, you can remove the wires from one hard drive or the other if you have to for certain maintenance tasks in the future. For instance, I like to run applejack on my mac hard drive but booting into single user mode is incompatible with the dual boot configuration I will discuss below. Remove your mac os hard drive from the computer and set it aside. Presumably it was in the top bay. Install your new hard drive into the top bay. (You will find the little mounting screws inside your computer.) Install Suse completely before reinstalling the mac hard drive. As you know, Suse reboots after installing disk 1, and on a couple of occasions I have had the mac os boot (from the second hard drive!) at that point. You want to avoid that frustration altogether and at the same time have the peace of mind that comes with knowing there is no way you are messing up your mac data while you install suse. At the beginning when you are installing Suse, take a close look at how it wants to set up the partitioning. I have noticed that if I am reinstalling Suse, and even if I have selected New Install (rather than update) it will not remove the old root partition but rather split a new one off the space that had previously been allocated for my home partition. If that happens, go to the bottom of that page and modify the partitioning scheme. Manually tell it to use the whole disk. Then you should get the same number and sizes of partitions that you had before. Another option is to insert your tiger dvd, (boot holding command-E to open the dvd tray, then hit the power button once to turn off the machine and again to restart, the tray will go in, hold down c and you will boot from the tiger dvd) and use the drive setup utility to format the hard drive. Choose one single partition of type free space. Then exit that program, shutdown, boot with command-E, remove tiger dvd, insert Suse disk 1, power off, power on. Once you get Suse completely installed and running, shutdown and install your mac hard drive. For dual boot purposes, you will want to have the mac hard drive in the second (lower) bay. Now reboot (Suse will boot). Go to My Computer, and find your mac hard drive. Right click (grab a two button mouse off one of those pcs of yours!), go to Properties, Meta Info and write down the device node (mine is /dev/sdb3). Start a Terminal shell and enter the following code: su (password) nano /etc/lilo.conf modify lilo.conf by adding these lines to the end: other=/dev/sdb3 label=macos (use your mac hard drive device node!) If you want, you can also change the default os to macos (I like this, then other people aren't messing around with my Suse): change the default line to: default = macos to save and exit: control-o, return, control-x Now you must run lilo to set up the configurations you entered! While still in root: /sbin/lilo When you boot, as soon as you hear the chime hold down the space bar for linux or do nothing and it will boot into the macos. If one of the linux partitions appears on your mac desktop (always does on mine), immediately eject it. Hope this helps. Let us know how it goes.
