On 10.5.1 I was able to start from my external drives with Tiger on them. (both USB and FireWire). I have a MacBook core duo that I ran the 10.5.2 combo updater and graphics update on and everything else is OK but can't start from any pre-Leopard disk any more. I tried restart with option key, startup disk in system prefs, and repaired the disk and the preferences. I keep Tiger on 2 of my 4 external disks for a couple of G4 computers we have. Even the Tiger disk won't work (retail). As I said above, the disks used to boot under 10.5.1 but not on 10.5.2 that is now on the MacBook. They work on G4's. Am I missing something? TIA
