Sounds like some kind of conflict, possible IRQ. when you use 2 mice (one
PS/2 one serial), you are also using 2 IRQs.

There is a quick fix however, get a USB mouse, both PS2 and USB work happily
together and USB doesn't use any IRQ at all.

Subject: [PCBUILD] Both ps/2 and serial mouse


> Hi, I need help. I have a problem using my fingers. I need a trackball
mouse and my pardner wants a reg. mouse. I am using the Logitech Trackan
Marble fx on the PS/2 port and my pardner is using the Logitech Optical
mouse on the Com1 serial port.
>      Under Windows 95, both work perfect. Under Windows 98SE, when you
first boot up and the plug and play installs them, both will work perfect
until you reboot. then the SERIAL port mouse will not work, showing a yellow
flag under the My Computer properties menu. You can remove the com1 device,
reboot and let windows find the com1 port mouse and both will again work OK
untill you reboot.. I have tried installing both manually, but still no
luck. There is no conflict shown when the yellow flag is show.
