How do I run a TSR (Terminate-and-Stay-Resident) program on the HP 95LX?

Use the built-in MEMO application to create two files: CONFIG.SYS and AUTOEXEC.BAT. The CONFIG.SYS file should contain the following line:

shell=command /p

(WARNING: It is important to include the single empty space between the word "command" and the "/p". You can lock up your 95LX otherwise.)

The AUTOEXEC.BAT file should contain the following two lines:

(tsr name) $sysmgr

The first line has the name of the TSR you want to run. The second has the command $SYSMGR, which starts the built-in System Manager. These files should be put in the root directory of your RAM card if you have one. They will also work in the root directory of the internal RAM disk. These files are executed whenever the system is rebooted. Before rebooting the system, quit all of your open applications, making sure to save files that you have modified. Then press <CTRL>-<ALT>-<DEL> to reboot the system. During the process of restarting the system, your 95LX executes the AUTOEXEC.BAT and CONFIG.SYS files.

The HP 95LX User's Guide contains instructions on how to use the SHELL command on page B-24.

WARNING: These commands represent a serious modification to your HP 95LX. You should be experienced with the use of CONFIG.SYS and AUTOEXEC.BAT files. If you make a mistake in these files, you may not be able to reboot the system. Therefore, you should only install these files on a RAM card. If there is a problem, you can remove the RAM card and the system will boot up in the normal way. If you put these two files on your internal RAM disk, back up the contents of your C: drive first.
