10.5: Create a single Intel+PowerPC diagnostic drive
Authored by: thornezilla on Oct 31, '07 01:14:08PM

To address the issue of what kind of partition can boot what kind of Mac, here's what I discovered.

The difference isn't "Intel vs PPC" for partitioned hard drives, but "Older Intel & PPC vs Intel 2.4GHz".

I had 4 different external FW Hard Drives, all partitioned with the older Apple Partition Map via Disk Utility. They all booted all my PPC and Intel Macs until the 2.4 GHz "Santa Rosa" chipset MacBookPro's shipped.

At that time I was forced to reformat two of the drives with GUID formatting, so that I could load/copy/restore a bootable OS for the new 2.4 GHz systems. These two drives can boot any of the new 2.4 GHz systems, but I don't use them to boot or repair the older Intel Macs or PPC systems.

The other two FW drives are used as before, to boot and repair the PPC and older Intel Macs. So even though Apple's documentation said that GUID formatting was required for Intel systems, it wasn't **required** until the Santa Rosa chipset shipped.

Can't address the main issue of a drive that will boot both, but will try it ASAP. Thanks again, MacOSX Hints!

Please let us know if this works on your SantaRosa machine. I'll be surprised if it doesn't work.... unless it requires a different Installer DVD.... which it absolutely shouldn't this early in the Leopard game.
