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,

Mark.

​The "Multiprocessing" folder contains a file named "Apple CPU Plugins" of type cpup. Looking at the resource "cpups", it seems to contain code to supplement the OS to support various newer CPUs and architectures.  The resources in the file are named (and contain):

PowerSurge2PPlugin:

"hammerhead" (old clone computers based off multiple PPC 604I believe)

G3Plugin:

Powerbook1,1

Core99Plugin:

uni-north

keylargo

PowerMac2,1

PowerMac2,2

PowerMac3,4

PowerMac3,5

PowerMac4,1

PowerBook3,3

PowerBook3,4

The "Open Transport ASLM Modules" file seem to be a collection of shared libraries, since many programs, once this file is removed from the extensions folder, refuses to run, for example Apple System Profiler.  OTLib$NBPScnr, OTLib$SerIAB are some examples of shared libraries contained within this file.  This is verified from the book "Sad Macs, Bombs, and Other Disasters: And what to Do about Them By Ted Landau

I will do more research.

Thanks,
