Computer does not recognize mouse due to incorrect mouse port designation.
Cause:
Mouse port designated in AUTOEXEC.BAT or CONFIG.SYS is wrong.
Solution:
Change the mouse port designation.
1) Edit the AUTOEXEC.BAT and CONFIG.SYS files and locate a line with the word 'MOUSE...' similar to one of the following:
a) In AUTOEXEC.BAT look for C:\DOS\MOUSE\MOUSE.COM /x
b) In CONFIG.SYS look for DEVICE=C:\DOS\MOUSE\MOUSE.SYS /x
2) After the word 'MOUSE' there may be a '/1' or '/2'. If the digit is a 1, change it to 2; if it is a 2, change it to a 1.
3) Save the changes, exit the file, and reboot the computer.
4) Watch for a message indicating that the mouse driver is being loaded during the bootup process.
5) Load an application that uses the mouse.
6) Attempt to use the mouse.
