Ok, so now we have this new slick DOS 5.0.
Now we "Don't need QEMM" to load drivers and TSRs high.

Well, I've just gotten a trial copy of 4Dos v3.02(looks good!),
but the DOS 5.0 loadhigh is internal to COMMAND.COM!

So this means what, boot DOS w/Command, have AUTOEXEC loadhigh
all the TSRs and then run 4Dos?
Seems like a waste of RAM, but I may have missed something.

Of course device drivers are no problem, but running PC/TCP alone
takes over 87K as TSRs.

Naturally, Loadhigh borrowed from Qemm doesn't see DOS5 highmem.

Also, I'd like to be able to move the EMS frame to overlap the BIOS.
I know that the BIOS uses the last 32K, but it's mirrored at f000.
Anyone able to do that?  EMM386 complains when I try frame=e800.
Doing this would yield 32K more UMB space for loadhigh.

Having just over 500K free is nice, but I was hoping for the 600K+
I should get if I could loadhigh AND dump COMMAND.

Helpful comments gratefully received.
Flames scornfully ignored.
