Thanks for the info, guys.
When I was last able to mount the REAL AmigaDOS drive, I copied the contents of the data to a couple of WinUAE hard disk files. I know I had to do a little tweaking to use an OS taken directly form a real A3000 under UAE. One glaring problem I have not been able to solve is my mouse pointer is not working! I looked for anything in WBstartup and the startup-sequence that could affect it and found nothing. It could be that perhaps the whole system just freezes on launch and I cannot tell the difference. Perhaps I can try some keyboard shortcuts. Any ideas? I really like the idea of using my "old system" with UAE as if I still have the old hardware rather than building an Amiga OS system natively for UAE. I have done this successfully, by the way. This is how I am able to get some control over the hard disk files for the transferred OS.
