First of all, thanks Randell for your private time and efforts you put into

Randell, can the parts of the Amiga OS themselves request protected memory?
{That is in some scenario where it is available.}

This is a simple question really and I presume the answer is simple also. I
am asking because I have forgotten the details regarding the attributes RAM
required by the OS must have.  {I wish I had the RTMs.}

Btw would someone run by me again the problems with making an Amiga virtual
machine for _development_ purposes.

An appropriate quote for this discussion of the GURU. :-)
