[comp.sys.ibm.pc] High Memory in DOS??

nksehgal@rodan.acs.syr.edu (03/29/91)

I have a TSR which is loaded high in memory(above 640K) using 386max,
This TSR write a string in memory to indicate that it is loaded as
a subsequent attempt to execute it first looks for the string.  The problem is
that it looks only in first 640K,  causing two copies to exist at the same time.

Can some DOS guru suggest if there is an internal list of memory blocks in
DOS that I can search for the string written out by first TSR. Or maybe 
anyother efficient way to check other than scan the entire address space of
386?

thanks in advance,

naresh
