That's 660MB.  A bit low (I get 1.5GB here), but should be enough to
start.

How do you run Windows XP? is that natively, or do you run it in some
VM on GNU/Linux?  If the latter, does that VM have any settings
regarding DPMI and/or memory?

Also, does the below also fail?

  C:\DJGPP\src\emacs-28.0.90\src> set TERM=internal
  C:\DJGPP\src\emacs-28.0.90\src> temacs -Q

And what's the layout of the Command Prompt window from which you
invoke temacs? how many lines by how many columns?

And finally, did you try to close the Command Prompt (thus killing
NTVDM), and then starting temacs from a fresh Command Prompt window?
IME, many failed attempts to build MS-DOS Emacs sometimes cause NTVDM
to be in some strange state, where stuff fails for no good reason, and
restarting NTVDM makes those problems go away.
