There is an old joke, often shown on the U.S. "Hee Haw" T.V. show of
about 30 years ago:  A man tells his doctor "Doc, it hurts when I do
this" (raises his arm, leg, etc.).   The doctor HITS him on the head
and replies "Well, DON'T DO that"!!

Re: your comments about UIDE/RDISK taking all of 4-GB memory, if you
have some application that needs some of that memory, DON'T LOAD the
drivers, or load them with /S switches that take LESS of XMS memory!
I believe it was you who said recently that "You cannot have it all"
and in this case, I agree -- If your system has one HUGE application
that needs memory, run the application ALONE, without UIDE or RDISK!

"Sounds good to me!", and you're free to write such a RAMdisk driver!
If there are no other DOS programs loaded that need/use 64-GB memory,
your driver gets "exclusive" use of that memory and should work fine!

Your item 6 is a problem, for me.   There are now 1.5 and 2-TERABYTE disks
available, thus not being able to alter the hard-disk, i.e. it is FULL and
cannot hold another 4-GB file, is unacceptable.   If really a possibility,
buy yourself ANOTHER 2-TB hard-disk!   Should be cheaper than trying to do
"special RAMdisk" or "64-GB XMS" drivers, merely for one application!

As above, you just MIGHT need to write a new program or RAMdisk driver by
yourself, to handle all this!   We all know DOS is NOT supported too much
any more, and "special things" just MIGHT require some "special efforts"!

Linux (still a "toy" system to me) is "not my department", and I admit
that I use DOS only to backup and restore Win/NT, whose "Opera" allows
me Internet access -- poor "Arachne" will not run for me, and I REFUSE
to use anything labeled "I.E." and suffer Gates & Co. SECURITY "bugs"!
Thus I cannot comment on the availability of DOS applications, since I
use very few of them.

Why don't you just run DeepBurner under Win/XT or whatever current Gates
& Co. Windows variant you prefer.    Remember, "You cannot have it all",
and there just MIGHT be a few applications which can be implemented more
quickly without DOS, using ["Horror of HORRORS"!] a variant of Windows!

You are most welcome! ;)
