Which says in part: "On a Mac OS X 10.5-compatible PowerPC-based Mac, make sure the external hard disk has a Partition Map Scheme of "Apple Partition Map (APM)"." "Once installation is complete, you will have an external hard disk that can start up ("boot") both PowerPC-based Macs (that are Mac OS X 10.5-compatible) and Intel-based Macs that were available when Mac OS X Leopard 10.5 was released." DU clearly states which format to use when and for what and adhere to this when installing to an IHD. Followed the article for an XHD and it works. Boot up supported even before appropriate "flavor" of updates. Any theories?
