I know this looks as if I am answering myself but, Themos has asked why use 
RPLMEM for remote boot clients and why load the REDIRector into 
conventional memory.

PW/DOS MICROSOFT WINDOWS SUPPORT GUIDE

"USING REMOTE BOOT TO RUN WINDOWS IN 386 ENHANCED MODE

Before you run Windows in 386 Enhanced Mode for the first time from a 
remote boot client, you must load the TSR program RPLMEM.  This TSR informs 
Windows that the area at the end of conventional memory is being used by 
the operating system and is unavailable to Windows."

The "book" says you only have to do this one time...probably meaning that 
it needs to be done one time for each boot session...since it is a TSR, it 
must be restarted every time after power is applied to the client.

PW/DOS MEMORY SOLUTIONS FOR CLIENT ADMINISTRATORS

p. 5-31  "When DOS is loaded into HMA, the Basic Redirector must be loaded into 
conventional memory.  The Enhanced Redirector can be loaded into EMS."

p. 5-19  "Before you can run Windows in 386 Enhanced Mode, you must load 
the TSR program \MSWINV30\RPLMEM.EXE on the PCSAV41 system file service.  
RPLMEM informas Windows that the area in memory from just below the 640K 
mark is being used by the Remote Boot task image."

p. 3-36  "If DOS is loaded into HMA, the Basic Redirector must be loaded 
into conventional memory..."

p. 3-35  (Under the section that outlines special steps to take when 
configuring clients that will be running Windows)  
"Put the Redirector (both Basic and Enhanced) into conventional 
memory or expanded memory (EMS).  Putting the redirector into extended 
memory (XMS) could cause conflicts with Windows."

p. 3-22  "If you are using Microsoft Windows in enhanced mode, make sure to 
put the Basic Redirector in conventional memory."

p. 3-24  "If you are using Microsoft Windows in enhanced mode, make sure to 
put the Enhanced Redirector in either conventional memory or expanded 
memory (EMS)."

I do not even desire to go into all of the technical reasons that the 
REDIRector should be loaded into conventional memory...I assume that with 
all of the above statements, that DEC really means it!

The reason we load REDIR into conventional memory is because we do not use 
EMS; we only use XMS with our memory manager (NETROOM) and load as much as 
possible into XMS...we don't use a page frame either.  Hence, REDIR goes 
into conventional (DOS is in HMA on our DOS5.0 units).
