Okay, so I'm able to boot with all extensions on. I switched out the PC2700 RAM that was causing AHT to failboot, and put in the one 256MB PC2600 stick that passed AHT. So I'm at stock RAM levels right now, but, whatever.

After I did that I turned off all the extensions and worked up to a maximum successful set . . . which turned out to be all of them. I should have tried booting again with extensions after the RAM switch. Oh well. It works now anyways.

The problem is, the system folder I got from the install CD is gutted. No AppleTalk control panel. No Mouse control panel. No File Sharing extension. That's for starters, as they're what I need right now.

So, I'm in the process of cataloging everything (all control panels, extensions, etc.) in the system folder including version numbers.

I'm then going to catalog the system folder in my Wallstreet PDQ (a 9.2.2 International update downloaded from Apple and added to a 9.1 UK retail install).

I will see what the differences are an start adding things to the gutted system folder on my MDD and see what works and what crashes.

I will then take this hybridized, bastard, Borgified system folder, and *archive it*. I will then test it for a month or two using lots of software.

If everything works, I'll have me a new, custom OS 9.2.2 install for 2003 MDD machines.

I'll keep you all posted.

Update: File Sharing is live on the MDD-Borg, and it and the Wallstreet are now talking to one another.
