Yeah I noticed when booting from a CDROM that my open windows are
remembered across sessions(!). This makes me think that OS 9 thinks the
HFS volume is a HD rather than a CDROM and so mounts it read/write on
boot. How would I find this out in OS9?

These images are definitely helpful, however what would be really useful
to know is exactly what the modules in question do:

- Multiprocessing (maybe uses a currently unimplemented CPU instruction
to facilitate faster multitasking?)

- Open Transport ASLM Modules (no idea what these do)

- Apple Audio Extension Module (is this just a standard sound driver or
other? I did get a backtrace once suggesting that it was trying to
access digital CDROM audio which is why it crashed. Then again if it
thinks that the CDROM is a HD then that's not going to help too much
here either).


ATB,
