If you have included the file MOUSE.SYS in your CONFIG.SYS file, repeat step 5 to modify the .SYS file as well. Just substitute .SYS for .COM in the instructions.

When you are going to use the program with which you had the mouse problem, you need to load the new mouse driver into the computer’s memory. There are two ways to do this:

❏Type the name of the new mouse driver at the MS-DOS command prompt and then start the program.

❏Modify your AUTOEXECBAT file (or another batch file) to include the name of the new mouse driver. See your MS-DOS Reference Manual for instructions.

Note

If you have already loaded the original mouse driver, reset the computer before you load the new one.

Memory Module Problems

If you added extra memory to your system by installing SIMMs and that memory is not operating properly, check the following:

1.Check to make sure that you set the memory configuration jumpers correctly and that they match your current SIMM configuration. See Chapter 5 for instructions on setting jumpers JP4 through JP8.

2.If the jumpers are set correctly but the memory count displayed by the power-on diagnostics program is incorrect, you or your dealer may not have installed the SIMMs correctly. They may be installed in the wrong sockets, they may be the wrong type of SIMM, or they may not be inserted all the way into their sockets. (Keep in mind that the memory count does not include the 384KB of memory between 640KB and 1MB.)
