Many many Macs over the years have had a minimum version of the OS they would boot from; 10.5 is the minimum for modern Intel Macs. Only the very first MacBooks, Mini's and IIRC the iMacs booted in 10.4, and at that they needed the version that came with them, not the retail version. 10.5 is the first retail version of OS X that booted on both architectures. No Intel mac could EVER boot from 10.3 (except the secret X86 builds maintained in Apple's R&D). However, Intel Macs need a GUID partition to BOOT from, but once booted, they should be able to see APM volumes without an issue. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to Low End Mac's G-Books list, a group for those using G3 iBooks and PowerBooks (we run a separate list for G4 'Books).
