Return to The Config.sys Documentation Project Main Page

The Run statement in your config.sys file is used to run a program during boot up. Programs started by Run are executed in the background. The following pages describe these entries:

RUN=Batserv.exe

This is used by the Watcom C/C++ Compiler.

  RUN=C:\Apps\Watcom_C\Binp\batserv.exe

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x	eCS 1.x	eCs 2.x
Yes	Yes	Yes	Yes	Yes	Yes

RUN=Cache.exe

This entry controls the behavior of the HPFS cache. It is normally not set in your config.sys. Set it only if you want to change the default settings. If you encounter any problems with this statement then delete it from your config.sys file and set it up in your startup.cmd file.

  RUN=C:\OS2\Cache.exe Parameters

Default settings:

LAZY: ON (use 1 thread)
BUFFERIDLE: 500 ms
MAXAGE: 5000 ms
DISKIDLE: 1000 ms
READAHEAD: ON

Parameters:

You can use the "/" or the "-" at the beginning of each parameter.

/LAZY:value

Value can be ON or OFF or in the range from 0 to 64 . Default = ON If this parameter is not set it defaults to 3 . The OS/2 online help says: "If this parameter is set no other parameters are allowed." This depends on your system, some user reported me that two lines gives errors at boot.

   o /LAZY:ON
   Lazy writing is on, three threads are used.

   o /LAZY:OFF
   Lazy writing is turned Off.

   o /LAZY:n
   n lazy write threads are used.

/DISKIDLE:value

Value can be in the range from 0 to 65535 . Default= 1000 The value is expressed in milliseconds. This is the amount of time that the disk is idle before data can be written from cache to disk.

/BUFFERIDLE:value

Value can be in the range from 0 to 65535 . Default= 500 The value is expressed in milliseconds. This is the amount of time that the cache-buffer can be idle before the cache data must be written to disk. The OS/2 Online help says that the BUFFERIDLE time must be smaller than the DISKIDLE time. I think this is wrong!

/MAXAGE:value

Value can be in the range from 0 to 65535 . Default= 5000 The value is expressed in milliseconds. This is the time data waits in the cache before the data is written to disk.

/READAHEAD:value

Value can be ON or OFF or 0 or 1 . This Parameter enables the read ahead buffer.

/DIRTYMAX:value

Value can be in the range from 0 to 65535 . The value is expressed in milliseconds.

/WRITECACHE:value

Value can be in the range from 0 to 65535 . The value is expressed in kilobytes.

See the examples below.

If you want to turn lazy writing off, add this line to your config.sys:

  RUN=C:\OS2\CACHE.EXE /LAZY:OFF

If you want to turn lazy writing on and set bufferidle to 4 seconds, add this line to your config.sys:

  RUN=C:\OS2\CACHE.EXE /BUFFERIDLE:4000

If you want to turn readahead off, add this line to your config.sys:

  RUN=C:\OS2\CACHE.EXE /READAHEAD:OFF

RUN=Cntrl.exe

It controls the stack for TCP/IP.

  RUN=C:\Mptn\Bin\Cntrl.exe Parameter

Parameters:

/V

This option enables the pointer and parameter verification by MPTS.

/SM value

Number of small mbufs that MPTS allocate at initialation. Small mbufs are 256 bytes long. Value can be in the range from 512 to 4096 in multiplies of 128. Other values are rounded up to the nearest multiple of 128. Default = 512

/LM value

Number of large mbufs that MPTS allocate at initialation. Large mbufs are 4096 bytes long. Value can be in the range from 64 to 180 in multiplies of 2. Default = 144

All data sectors received by MPTS are stored in buffers called mbuf, or clusters. There are two types of mbufs. Small mbufs and large mbufs. If needed MPTS can dynamically allocate additional mbufs.
