Thank you for taking the time to help. I use Word Perfect 5.1
for DOS (says WP 5.1 03/09/92 for its date in the help page
therein at pressing F-3). I am trying desperately but with little
success to get it to run on more recent computer(s), particularly
on a Asus Eee PC netbook laptop EeePC900-WO (sn:880AAQO82586
ZEROS & OHs MAYBE MIXED UP, NO WAY TO TELL THERE).

I bought it on February 27, 2009 at Best Buy. It has for the
Operating System: Microsoft Windows XP Home Edition version 2002
with Service Pack 3. When the Dos window is activated it says
that it has "Microsoft Windows XP [Version 5.1.2600] © copyright
1985-2001 Microsoft Corp." which I don't think is referring to the
Word Perfect there. Its processor is an Intel® Celeron® M at
900MHz. It has 0.99 GB (899MHz) of RAM "Physical Address
Extension".

The technical support people at Asus seem to be all thumbs and
are unable or unwilling to help but one of them referred me here
to maybe get Word Perfect 5.1 up and running on it.

I have been able to get other DOS programs working on it and on
other computers running Windows XP Operating Systems but not on
this one or my Vista Ultimate 32 bit or 64 bit computers even
when trying to get it up in DOSBox 0.74 (I have not used DOSBox
very long, 1 day but I got other DOS programs up in it). On the
Eee Netbook I get the error message: "Program too big to fit in
memory" and as well on the Vista Computer's DOS and on using the
DosBox on those other computers it simply locks up. I have a Pentium 4
desktop that it runs well on and therein when you right-click the
Word Perfect Icon on the desktop, then "properties" It is set up
with the following in "program" tab:

Cmdline: C:\Wp51\WP.EXE,
Working: C:\Wp51,
Batch file: (empty),
Shortcut: (None),
Run: Normal window,
Expanded (EMS) Memory: Eee does not have this, others set to "None" &

I've tried various other.
Extended (XMS) Memory: Eee does not have this, others set to "None" &

I've tried various other.

I have tried to use those settings in the other Vista computers
with out success so far (as well as all the other tab settings
there set identical). I have also tried in these computers to
launch it in DOS windows from command lines typing "wp" ENTER
with no success: (I tried both between windowed and full-screen
mode and this problem occurs in both windowed mode & full-screen
mode in the nonworking computers). Right now as its running on my
Desktop XP computer it is running 50 lines when in full screen
but I have been able to see it run in 25 lines in full screen
mode when I boot it up pressing F8 in "Safe Mode" and like it
better as texts are bigger but it mysteriously stopped doing that
and presented a blue screen just then, as well. If you can tell
me how to run it without the blue background and larger text as
it used to do on my old PII or 486DX it would be nice, as well as
this blue background hurts my eyes (I like black background and
white text). I have thousands of macros that I use in Word Perfect
and it is my favorite word processor for spell-checking. Following
are autoxec.bat and config.sys files tried:

AUTOEXC.BAT CONTENTS TRIED FROM OLD DOS COMPUTERS:
C:\SMARTDRV.EXE /L /X
PROMPT $P$G
PATH c:\wp51;c:\DEFPLUS;
LH /L:1,13984
C:\DOS\share
rem SET TEMP=C:\WINDOWS\TEMP

CONFIG.SYS FILE CONTENTS TRIED FROM OLD DOS COMPUTERS:
dos=umb
dos=high
devicehigh=c:\dos\setver.exe
device=c:\himem.sys
device=c:\dos\emm386.exe ram
Files=50
fcbs=16,8
buffers=20,0
stacks=20,256
lastdrive=d:

The above config.sys and autoexec.bat was tried in all the
failing computers with no success including different buffer,
files (tried 50 or more), stacks etc (what should these be
set to?). The working XP desktop has NOTHING in those files
as pulled up in editor but works anyway and the Eee seems
not to hold them and will get error MSGS at times ("unknown
error" it says, "error 87" while editing autoexec.bat).
Also I recently have been using Word Perfect and executing
heavy duty macro actions on my XP desktop and it suddenly
said it could not find files that were on the disk that
these macros were accessing for no apparent reason which is
puzzling as it never did this before in XP or old DOS
computers. I've heard that "memmaker" command is used
to help setup older computers, is this used these days?
Thank you very much for your kind assistance.
