To save space I have included ONLY the lines that changed from the
defualt CONFIG.SYS file when installed.

REMEMBER, ALL changes in here are SYSTEM WIDE.  For additions to EACH
DOS SESSION, you can use the DOS SESSION SETTING for EACH session.

IFS=C:\OS2\HPFS.IFS  /CACHE:2048 /CRECL:16  /AUTOCHECK:CDE

   NOTE:  For the HPFS file system.  If you using only the FAT system
   this SHOULD BE be REM'd out.  (Put the word REM in from of the line)
   as it takes 500K of RAM to use HPFS, memory that could well be used
   for something else.
   NOTE: /CACHE:2048.  Since I only have the HPFS running I am using 2MB
   for this cache.
   NOTE: /CRECL:16  Defines the size of the maximum record size.
         Experiment with this setting.
   NOTE: /AUTOCHECK:CDE  Runs FDISK is OS/2 is not shutdown properly.
         Leave this in there, and list the HPFS drives ONLY,  The
         DISKCACHE line below is for FAT partitions.

SET PROMPT=$P$G
   NOTE: Changing this SET PROMPT line is totally up to the individual

PRIORITY_DISK_IO=NO
   NOTE: Give equal performance to all session, foreground as well as
   background.  Set to YES will give the foreground session priority,
   something you don't want to do with multi-node systems.

FILES=50
BUFFERS=40
   NOTE: I increased both FILES and BUFFERS

DISKCACHE=64
   NOTE: ONLY 64K as only the floppies here are FAT, the rest of the
   system is HPFS and that cache is on the top line above that starts
   with IFS=C:\OS2\HPFS

DISKCACHE=1024,LW,AC:C
   NOTE:  Although I am NOT using this line I put it here for you that
   will be running FAT partitions:

   THIS IS FOR FAT PARTITIONS ONLY!

   1024K is the size of the cache.  Total cache recommended is 2MB
   split between the FAT and the HPFS.  If you have only FAT then make
   this 2048K.  The same goes for only HFPS partitions (like my setup)
   it's set to 2048K.  If you have both file systems (FAT & HPFS) spilt
   the cache accordingly.

   LW, is for Lazy Writes.  This means that OS/2 will write to the disk
   at a time when the processor is not busy which helps the speed as
   it's not writing to the cache when the system is busy.

   AC:C   This is the AUTOCHECK command that will run FDISK on your
   partitions if OS/2 is not shutdown correctly...  Add ALL your FAT
   partitions to this.


MAXWAIT=1
   NOTE:  Reduced from 3 to 1

SWAPPATH=D:\OS2 2048 10240
   NOTE:  OS/2 will set the size of the SWAPPER.DAT file according to
   the amount of RAM memory.  Although I have 16MB, I have a large swap
   file just in case.  I recommend this to anyone that has the disk
   space.

PRIORITY=DYNAMIC
   NOTE:  Recommended by David Terry, head programmer at CDC.

THREADS=512 (512 being the maximum, 256 might work better for you, again
             you need to experiment.)
   NOTE:  Recommended by Boca, OS/2 Development Team

PRINTMONBUFSIZE=134,0,0
   NOTE:  Size must remain at 134, but if you have only 1 printer reduce
   the last two to 0 to save memory.

DEVICE=C:\OS2\VDISK.SYS 4096 128 512
   NOTE: RAMDISK Command.  You'll need to put this in as OS/2 does not.

REM DEVICE=C:\OS2\MDOS\VCDROM.SYS
   NOTE:  Be sure to REM out this line if you don't have a CD-ROM
   installed.

REM DEVICE=C:\OS2\COM.SYS
REM DEVICE=C:\OS2\MDOS\VCOM.SYS
   NOTE:  Rem out the default com drivers if you are using the SIO
   drives. (see just below).

DEVICE=C:\SIO.SYS
DEVICE=C:\VSIO.SYS
   NOTE:  SIO/VSIO COM drivers.  Recommended..


Hoepfully I have covered ALL the changes that I made to my config.sys
file for optimium performance.
