    I have an Intel iMac, and three PPCs. I just found out I can boot my Intel Mac from my iBook. I even had extended desktop, when I did this. I have a second monitor connected to my iMac.

    It would make backing up everything a little easier, if I could format all of my external drives to APM. Why are all Intels formatted with GUID, when APM will work on all Macs? Can I clone a HDD formatted to APM to a HDD formatted to GUID, and will it be bootable?
