In the book "OS-X the Missing Manual" they suggest making a copy of your OS9 system folder and then setting OSX classic system preferences to use that copy. This may be overly conservative; I can't say that I know this has saved me any trouble, but it comforts me to know that OSX or some classic mode configuration change that I might try won't clobber my 'production' OS9. I still need to boot standalone OS9 because one important application (Finale) has a printing problem when running under OSX classic mode, and because my audio recording/editing application (Audiodesk) won't run at all under classic mode. I like having an HD partition available for installing the next OS release, whatever it might be, so that the install won't affect in any way my current running OS. Once the new OS is up and running then this old OS partition is still available as an emergency bootable system. Having a second bootable OSX system is particularly handy since the Apple supplied OSX bootable CDs (system install CD) will not let you drop out of the installer to a command line or to the finder. It will, however, let you drop out to the OSX disk utility for performing general HD repair or new HD preparation tasks. Another emergency boot system option is to install a system on an external Firewire HD. This can be booted via the restart and hold down the 'option' key method. I don't know how new the Mac has to be to have this feature. My 2001 G4 'digital audio' machine can do it. The partition for OSX needs to be larger than one might think. I learned this the hard way. Apparently there is some dynamic use of space there (swap space presumably). If the OSX boot partition runs short of space, and 'short' occurs before free space gets to zero, unpleasant things happen like preferences get lost. My OSX 10.2.3 boot partition is 4.7GB. That is OK as long as I watch carefully what is accumulating in my home directory, in the applications directory, etc. But it doesn't take long running things eg. like Toast/Jam creating lots of audio files, to run low on space. Applications typically can be setup to control where they place their files, but the first time you run some new application you may forget to set that and end up getting into boot drive free space problems. I'll eventually get annoyed enough to try to move my home directory off of the OSX boot partition. So I don't know what to recommend except to say that a 4.7GB partition hasn't been large enough to be completely safe for me. -ct
