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.
