On a system with a PS/2 mouse, but just an AT Keyboard, is the mouse alone on a controller? Also, what is that controller? I have an odd mouse issue and had to switch to a serial mouse.
When I boot the system with a PS/2 mouse connected, all is well until I start using the mouse. It will work for a moment, then freak out. It will move all over the screen like hitting the hyperspace button on Defender. Not only will it do that, but it randomly selects icons and menus. They only way to stop it is using keystrokes to restart. It even does when mouse support for the BIOS setup is turned on and I enter the BIOS.
I have tried several mice, tried different header to PS/2 connectors.... I did have to replace the leaking battery in the area, but when this started happening, I never noticed the battery leaking. It was months later a leak developed. Still, I can't rule it out. I really want to get the mouse back on the port as the serial port won't allow me to use my KVM.
I'm attaching a pic of the board. One is a closeup of the battery and PS/2 mouse header and the other is a full view with battery removed (I found no evidence of trace damage). Maybe you can see something I missed, or help locate the controller IC.
