And which bears little resemblance to what I am talking about.  For those 
of you who have kept your nitros9 tree uptodate via the use of CVS, the src 
tree has a subtree of level 3, for both 68 and 63 09 stuff.  It is 
supposedly very easy to re-arrange your boot files to put all the RBF stuff 
in one group, and the SCF stuff into another, with an isolator module in 
the bootfile between the two groups, which changes the basic memory mapping 
and essentially allows the os to use quite a few pages more than 64k of 
memory by giving each of the categories of drivers its own 64k memory map 
in addition to giving grfdrv its own workspace.  Obviously needs more than 
the stock 128k of ram to do it well.

I believe the theory is good, but that perhaps I'm miss-understanding 
something, but I have not been able in probably 20 tries, to make a boot 
able disk. Whether or not my failure is related to having 2 megs of dram 
remains to be determined.

And any questions I've had about it have been answered by the sounds of 
Carlsbad Caverns, a huge mostly empty space.

Cheers, Gene
