486pc 33mhz 16 megs of memory dos v6.22 & win v3.1. Have tried different mouses and mouse drivers I have only com1 available and addressed it to com1. It works in DOS but when windows comesup at the beginning you can move the mouse but when windows is finished setting up it does not work. Been trying to resolve for four days. used microsoft mouse & non-microsoft. No ps/2 port available been using serial mouses. Is there something in the sys file or win ini file that I need to correct. Anysuggestions will be appreciated as soon as possible.
