CONFIG.SYS - SET Statements

Return to The Config.sys Documentation Project Main Page

Environment variables are stored by OS/2 in memory and can be called by any program. They are used by many programs to store information (for example, the install path) or some configuration information. If you want to see a list of all installed environment variables and their values, type "Set" in an OS/2 window. If the list is too long, you can redirect the screen output to a file, simply type this:

SET >output.txt

General Tips

Note that SET commands in CONFIG.SYS behave differently than when entered on the command line.

So, when you issue the following comands in a OS/2 session:

SET TEMP=C:\TMP
SET TMP=%TEMP%

you get:

TEMP=C:\TMP 
TMP=C:\TMP

But, if you add the same lines to CONFIG.SYS:

SET TEMP=C:\TMP 
SET TMP=%TEMP%

you get:

TEMP=C:\TMP
TMP=%TEMP%

but not TMP=C:\TMP. The enviroment variable TMP now has the value composed by the letters "%", "T", "E", "M", "P", "%". For that reason, in CONFIG.SYS, you must write the values explicitly as follows:

SET TEMP=C:\TMP
SET TMP=C:\TMP

This is because variables are not expanded during CONFIG.SYS processing, but they are when run from a shell (command line).

This environment variable is only useful in your install diskettes CONFIG.SYS file. If you find it in your normal CONFIG.SYS file, than you can delete it. If it is set up, OS/2 copies all standard drivers from the diskettes to your harddisk during the install process. If it is not set up, OS/2 will copy all drivers from the CD-Rom. If your hardware needs newer drivers than that on the install CD-Rom, you can copy the new drivers to the install diskettes. And set in the CONFIG.SYS on the install diskettes the CopyfromFloppy variable to "On".

SET CopyFromFloppy=Value

Value can be On or 1.

You must enable the delete directory function for every partition that you want to be able to recover files from.

SET DELDIR=Path1,Size1;Path2,Size2

Parameters:

Path - Path must be a full path to an existing directory.
Size - Size can be any value expressed in Kbytes.

See the examples below.

To use 4 megabytes of space for the undelete function on partition C: and 10 megabytes for the undelete function on partition E:, add this line to your CONFIG.SYS file:

SHOWEXTENDEDPOWERMENU

This is related to the software support package for Intel's SpeedStep dynamic frequency scaling technology (codenamed Geyserville). Mobile Intel Pentium processors support additional CPU and Throttle states to maximize battery life and optimize performance. The number of CPU states depends on the processor model and maximum frequency.

While the Geyserville daemon (GSVDAEMN) controls CPU throttling, it is possible to enable the overview of the CPU and Throttle states in the Power object. To control the states overview, the following statement should be used in the CONFIG.SYS file:

SET SHOWEXTENDEDPOWERMENU=<value>

where <value> is one of the following:

NO - the states overview are disabled, same as no "SET SHOWEXTENDEDPOWERMENU" statement in the CONFIG.SYS; (this is the default option)
YES - the states overview are enabled.

NOTE: Extended power state information is shown in English only prior to eComStation, which patches the related dll with updated resources when installed via eCSMT.

The default for Java_Clock_Resolution is 10 milliseconds, and this is generally rounded to 1 millisecond accuracy. If you need to ensure that the best Java performance is obtained when using currentTimeMillis, SET Java_Clock_Resolution = 32. This can be important when running Java benchmarks.

So the Browser contact a Domain name Server (DNS) and ask for the IP address. This takes some time, to speed up internet connection you can define in the Hosts file the hostnames and the IP addresses.

OS/2 will only use Hosts file if Use_Hosts_First is set to 1. You can define all kind of hosts www-server, mail-server, news-server, ftp-server or whatever else. To get the IP address for a host type "host" and the hostname in an OS/2 window. The actual Path for the host file is defined by the Etc environment variable.
