I did some more playing with this, without luck.
I believe the patch you mentioned is only for UEFI systems.
In my case, I had the bios set to Legacy Only, CSM Enabled. I saw a warp stock video with DavidA - and it seemed he was saying those are the best setting for AOS.
I also tried creating a program object on the desktop with command.com - In both cases I get a message that the mouse driver loaded and then lockup, only the CAD menu will load.
In the linux world, I would do something like strace command.com - and trace through the system calls. How can that be accomplished in AOS?
