- My friend has a 486/33 with 16MB of memory and found OS/2 slow at
- first. He tweaked his config.sys file a bit, and now it is very fast.
- He said that the most important thing he did involved the caches.
- Following is the complete text of his config.sys: (my comments
- interspersed)
-
- Someone may want to upload this somewhere.
-
- -------------- BEGIN FILE ---------------
-
-
- >IFS=C:\OS2\HPFS.IFS /CACHE:512 /CRECL:4 /AUTOCHECK:C
-
- This is necessary for HPFS support. Note the cache size if you have
- some problems. Add any additional HPFS drives to the /AUTOCHECK
- parameter. This parameter allows CHKDSK to run automatically if you
- boot and HPFS has a problem.
-
- >PROTSHELL=C:\OS2\PMSHELL.EXE
-
- This is Presentation Manager. Don't change this or you'll lose your
- GUI, and your session manager.
-
- >SET USER_INI=C:\OS2\OS2.INI
- >SET SYSTEM_INI=C:\OS2\OS2SYS.INI
- >SET OS2_SHELL=C:\OS2\CMD.EXE
- >SET AUTOSTART=PROGRAMS,TASKLIST,FOLDERS
-
- >SET RUNWORKPLACE=C:\OS2\PMSHELL.EXE
-
- This is WPS. Set it to C:\OS2\CMD.EXE if you don't want WPS. You can
- always run WPS as an app (start PMSHELL) if you need it later.
-
- >SET COMSPEC=C:\OS2\CMD.EXE
-
- >LIBPATH=.;C:\OS2\DLL;C:\OS2\MDOS;C:\;C:\OS2\APPS\DLL;C:\USER\DLL;
-
- OS/2 DLL files will only be searched for along this path.
-
- >SET PATH=C:\OS2;C:\OS2\SYSTEM;C:\OS2\MDOS\WINOS2;C:\OS2\INSTALL;C:\OS2\MDOS;C:\OS2\APPS;
-
- This is the path along which programs are searched for.
-
- >SET DPATH=C:\OS2;C:\OS2\SYSTEM;C:\OS2\MDOS\WINOS2;C:\OS2\INSTALL;C:\;C:\OS2\BITMAP;C:\OS2\MDOS;C:\OS2\APPS;
-
- This is the path along which data files may be searched for (a-la
- DOS's APPEND command)
-
- >SET PROMPT=$i[$p]
-
- >SET HELP=C:\OS2\HELP;C:\OS2\HELP\TUTORIAL
-
- The VIEW.EXE help viewer looks along this path.
-
- >SET GLOSSARY=C:\OS2\HELP\GLOSS;
-
- >PRIORITY_DISK_IO=NO
-
- If this is YES, then disk access will take higer priority than
- processing. You may want this on in some situations. Note that IBM's
- default is YES.
-
- >FILES=32
-
- This is for DOS box sessions only.
-
- >DEVICE=C:\OS2\TESTCFG.SYS
- >DEVICE=C:\OS2\DOS.SYS
- >DEVICE=C:\OS2\PMDD.SYS
-
- >BUFFERS=64
-
- This is also for DOS only.
-
- >IOPL=YES
-
- >DISKCACHE=256,LW,32
-
- This controls disk caching for FAT volumes, including floppies. The
- LW is for lazy writing. Note that it's larger than the default 64K
-
- >MAXWAIT=3
-
- This is the maximum amount of time a process can wait for the
- processor. I think it's in miliseconds.
-
- >MEMMAN=SWAP,PROTECT
-
- If you have plenty of memory and don't care about running out, you can
- remove "SWAP", and the system won't swap memory any more. I don't
- know what "PROTECT" does, but I'd leave it alone.
-
- >SWAPPATH=C:\OS2\SYSTEM 2048 2048
-
- This controls where your swapper.dat file goes. The parameters
- represent the initial size of the file, and the minimum size of the
- file. These parameters are for at 16MB machine. You can set the to
- different values - the defaults are listed in one of the pamphlets
- that comes with OS/2.
-
- >BREAK=OFF
-
- This is for DOS sessions.
-
- >THREADS=2048
-
- This is the maximum number of threads the system can have at once.
- Leave it alone unless you have a problem with it.
-
- >PRINTMONBUFSIZE=2048,134,134
-
- This controls the printer's buffering. I don't know if it's for DOS
- sessions or for all sessions.
-
- >COUNTRY=001,C:\OS2\SYSTEM\COUNTRY.SYS
- >SET KEYS=ON
-
- >SET DELDIR=C:\DELETE,512;
-
- This allows the undelete function to work. By default, this line is
- REMarked off.
-
- >BASEDEV=PRINT01.SYS
- >BASEDEV=IBM1FLPY.ADD
- >BASEDEV=IBM1S506.ADD
- >BASEDEV=OS2DASD.DMD
- >SET EPATH=C:\OS2\APPS
-
- >DEVICE=C:\OS2\APPS\SASYNCDA.SYS
-
- This helps DOS sessions use the COM port.
-
- >PROTECTONLY=NO
-
- Set this to YES to eliminate DOS and WIN-OS2 sessions.
-
- >SHELL=C:\OS2\MDOS\COMMAND.COM C:\OS2\MDOS /P /E:2048
- >FCBS=16,8
- >RMSIZE=640
-
- These are default DOS box settings.
-
- >DEVICE=C:\OS2\MDOS\VEMM.SYS
- >DEVICE=C:\OS2\MDOS\VMOUSE.SYS
- >DOS=HIGH,UMB
- >DEVICE=C:\OS2\MDOS\VDPX.SYS
- >DEVICE=C:\OS2\MDOS\VXMS.SYS /UMB
- >DEVICE=C:\OS2\MDOS\VDPMI.SYS
- >DEVICE=C:\OS2\MDOS\VWIN.SYS
- >DEVICE=C:\OS2\MDOS\VCDROM.SYS
-
- These are more default DOS box settings. The DEVICE= lines are
- virtual device drivers to emulate EMS memory, a mouse, DPMI, Extended
- memory, Windows, and CD-ROM drivers. I don't know wht DPX is.
-
- >DEVINFO=SCR,VGA,C:\OS2\VIOTBL.DCP
- >SET VIDEO_DEVICES=VIO_VGA
- >SET VIO_VGA=DEVICE(BVHVGA,BVHSVGA)
-
- These are for video support, including codepage support for the display.
-
- >DEVICE=C:\OS2\MDOS\VSVGA.SYS
-
- This allows DOS sessions to use SVGA modes, when in conjunction with
- the SVGA ON command.
-
- >DEVICE=C:\OS2\POINTDD.SYS
- >DEVICE=C:\OS2\MOUSE.SYS SERIAL=COM1
-
- These two drivers together provide your mouse. If you have a Logitech
- driver installed, there may be different parameters and also a
- PCLOGIC.SYS driver here.
-
- >DEVICE=C:\OS2\COM.SYS
- >DEVICE=C:\OS2\MDOS\VCOM.SYS
-
- These provide your serial I/O. Add parameters to them to access
- non-standard COM ports (like COM3 and COM4 on ISA machines). Note
- that these must be loaded AFTER the mouse support or you won't have a
- mouse.
-
- >CODEPAGE=437,850
-
- This sets up the useable code pages in the system. 437 is USA, and
- 850 is international. You may have others as well.
-
- >DEVINFO=KBD,US,C:\OS2\KEYBOARD.DCP
-
- This defines the keyboard as USA-ASCII, using the KEYBOARD.DCP file to
- describe what that means.
-
- >SET TEMP=C:\TMP
- >SET TMP=C:\TMP
-
- These are environment variables that are always useful to have around.
- Be sure that the C:\TMP directory exists.
