SUMMARY
=======
A terminate-and-stay-resident (TSR) program is a utility that resides in memory
while other applications are executing.
In general, TSRs work around MS-DOS (that is, shortcuts are used). TSRs also make
assumptions in the way MS-DOS acts. However, the assumptions that TSRs make with
one version of MS-DOS may not apply in other versions.
For these reasons, it is a good general troubleshooting technique to not load TSR
programs. TSRs can interfere with normal troubleshooting and testing.
MORE INFORMATION
================
Examples of TSRs are mouse drivers, some menu programs, Sidekick, Append, and
Mirror. Note that batch files are never TSRs. To troubleshoot TSRs, do the
following:
1. Do not load any TSRs. Remark (rem) out all TSRs in the CONFIG.SYS and
AUTOEXEC.BAT files. For example:
rem c:\dos\doskey
2. If the problem is resolved and MS-DOS 5.0 is being used, load all TSRs low.
Some TSRs expand and contract. When loaded into high or upper memory, TSRs
can cause conflicts with other devices or utilities.
3. If a TSR is causing the problem, do the following:
- Consult this knowledge base for information on the software.
- Contact the TSR manufacturer for help and information.
