Here's how to get 625k Free at the dos prompt,using only MS-DOS !
First you need a 386 or better , MS-DOS 5.0 , Norton Utilities NDOS.com ,
and the current versions of EMM386.exe & Himem.sys .
(They come with Windows 3.1 , and I believe they can be downloaded from any
decent BBs , like this one).
This is how I set up my C & T 386 sx with 6meg of extended memory
Config.sys
buffers=2
FILES=8
STACKS=0,0
lastdrive=d:
fcbs=1
DEVICE=C:\sys\HIMEM.SYS
dos=high,umb
DEVICE=C:\sys\EMM386.EXE ram 2000 i=e000-efff i=b000-b7ff frame=e000
devicehigh=c:\sys\mouse.sys /y
SHELL=C:\ndos.com /u /e:128
DEVICEhigh=C:\S\STACKER.COM C:\STACVOL.000
DEVICEHIGH=C:\sys\ansi.sys
@Echo Off
autoexec.bat
@echo off
lh c:\prnt\dmp /mx:24 /mxp
c:\sys\umbfiles=44
SET PCPLUS=d:\PCP
LH d:\pct\PC-CACHE.com /WRITE=ON/quiet/sizext=1700
PATH d:\PCT;C:\DOS;c:\ut;c:\sys;d:\acad;C:\S;d:\nu

I think Microsoft should offer a free upgrade to DOS 5.0 include the new versions of there extenders , AND a command interpreter such as NDOS , Looks
like dos 5.1 to me . This could turn most after market memory managers into
Shelfware! What do you think ?
