Here are copies of my CONFIG.SYS, AUTOEXEC.BAT, MI printout, and MEM /C printout. Using this configuration, I got 616.0K (That's 630,784 bytes folks) of usable memory under 640K. This is using the MS DOS 5.0/HIMEM.SYS/EMM386.EXE combination. I am using a Gateway 2000 386/33C with 4megs of RAM and a 120MB IDE hard drive. One thing to do to get more memory is to keep the environment small. Anything that is shown when you type SET at the prompt is in the environemt. Make directory names that are put in the path short(the longer the path, the more memory that is used). Keep your SET= statements to a minimum. Also keep them simple. Set LASTDRIVE to the lowest drive letter needed. I you have one HD partition, and don't plan on using a ramdrive place LASTDRIVE=C into you CONFIG.SYS. Other things to do in the CONFIG.SYS is to place FCBS=1 and STACKS=0,0 on separate lines. Keep the number of files in the CONFIG.SYS down to the smallest that you need. There is also a PC Magazine utility called UMBFILES.COM that will place your files into the UMB. If you use this utility, the minimum files in the CONFIG.SYS must be 8, as this is the minimum allowable by MS-DOS, and the rest will be loaded high. ******************************************************************************* CONFIG.SYS BREAK=ON DEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\DOS\EMM386.EXE NOEMS DOS=HIGH,UMB STACKS=0,0 FCBS=1 FILES=30 BUFFERS=2 LASTDRIVE=C ******************************************************************************* AUTOEXEC.BAT @ECHO OFF PROMPT $P) PATH=C:\;C:\WINDOWS;C:\NDW;C:\PCTOOLS;C:\DOS;C:\NU;C:\QEMM;C:\UTILS;C:\PKZ;C:\A RJ;C:\VPC SET TEMP=C:\TMP EP /ON IMAGE C:\STAR\UTIL\VMODE MONITOR C:\UTILS\SPEEDER + LH C:\MOUSE\MOUSE.COM LH C:\DOS\DOSKEY /HISTORY LH C:\WINDOWS\AD-DOS.COM LH C:\PCTOOLS\PC-CACHE/SIZEXT=512/WRITE=ON/V1/QUIET WIN : LH C:\PCTOOLS\SWAPSH /N PCSHELL/R ******************************************************************************* MI.COM (or MI/A) Memory Info V7.1 (c)1991 Central Point Software, Inc.
