See if this is possible

That would be awesome! As it is, the 140K disk barely fits a useful system.

@xandark, start by rechecking the whole "ProDOS.FX Crazy Format" subsystem:

Just came up with an idea this morning which I'm putting together - instead of trying to figure out how to make a 192K .po image that maybe ADTPro will understand, I'm putting together a 140K image which contains a PAK of the 192K install and a small script to help automate the installation. Will require 2 drives to do it since one will contain the PAK and the other will be the 192K target disk, but will work. Tricky part is getting the files for the 192 image right so I don't go over nor do I leave too little space behind.

But going to try to see if I can shuffle things enough to utilize BOTH drives as the install since we're already assuming 2 drives and disks dedicated to a2osx, but without killing dependencies (e.g. if I put dev tools or man pages on 2nd drive so it can be swapped out for something else, it won't halt the system). Experimenting...

you need to provide .WOZ files....PO cannot handle tricky track layout
i fear we need to make ADTPro able to handle properly .WOZ files

other possibility would be to use a 140K FX BOOT disk and write BASIC code running under BASICFX.SYSTEM ....but may require a UNPAK tool running under BASICFX.SYSTEM

BASIC program would make "A2OSX System Disks....." 140k 192k .....etc....

...that is the idea I'm working on; without ADTPro handling a disk format that would support the 192 (alright, so WOZ instead of PO), we create a 140K distribution disk which formats and unpacks to those 192K disks. So the 140K will boot, but it only contains enough to create the 192K target disks (e.g. it has base a2osx, a PAK file, and a script to unPAK to target 192 disks).
