I have a dual boot (OS 9/OS X) Dual-500
Gigabit Ethernet G4 machine.
I regularly go back and forth (usually to
play Unreal Tournament on OS 9). Since
the OS X 10.2.8 update, I am getting
pretty consistent hangs when attempting
to reboot from OS 9 to OS X. Norton Disk
Doctor finds problems with the drives.
Norton Speed Disk won't run to completion
even after successfully running Norton
Disk Doctor.
It looks like the OS X 10.2.8 update does
install some new Open Transport files in
OS 9.
