Warp 4 Config.sys

Does anyone have any information on what is needed and what is not in OS/2 Warp 4 Config.sya file? I am using my computer for basic stuff, and I do not think I need all the drivers that are loaded as default. I understand some of the basic drivers, but I would like to get a better understanding before I rem or remove any drivers.

Do you use HPFS format in one drive, if no you can remove the IFS line (at the top) of your config.sys (you save memory).

If you do not use HPFS,
and never plan to use HPFS, remove:
IFS=E:\OS2\HPFS.IFS /CACHE:2048 /CRECL:64 /AUTOCHECK:E

If you never will use a CD-ROM, remove:
IFS=E:\OS2\BOOT\CDFS.IFS /Q

If you do not have a printer, remove:
BASEDEV=PRINT01.SYS

If all your disks *and* all your CD-ROM devices use SCSI, remove:
BASEDEV=IBM1S506.ADD

If you never plan to read specially-formatted
extra-capacity diskettes written by MICROSOFT, remove:
BASEDEV=XDFLOPPY.FLT

If you have *NO* SCSI devices, remove:
BASEDEV=OS2SCSI.DMD
and
BASEDEV=AHA152X.ADD

If you never plan to use UltiMail Lite/2,
remove the reference to it from your 'SET PATH' and your 'SET HELP' statements.

If you ever *accidentally* delete files,
and then want to use 'UNDELETE' to recover
them, then remove the 'REM' from this 'SET DELDIR' statement:

REM SET DELDIR=C:\DELETE,512;E:\DELETE,512;

Is this correct for your geography:
SET TZ=EST5EDT

Is this correct:
SET HOSTNAME=MYHOSTNAME
It is quite a "boring" choice of names. :-)

Do you really need this many threads?
I rarely need more than 100 threads,
and never more than 500.
THREADS=1024

Do you have a SoundBlaster AWE 32 card
installed?  If not, then remove:
DEVICE=E:\MMOS2\SBAWED2.SYS /C:1 /D:1 /H:5 /I:5 /A:220 /B:8 /M:330 /N:SBAUD1$ /Q /P

I've heard that moving the 'DEVINFO'
commands to the "top" of this file
will improve performance.

DEVINFO=KBD,US,E:\OS2\KEYBOARD.DCP
DEVINFO=SCR,VGA,E:\OS2\BOOT\VIOTBL.DCP
