Hi Barbara, I tried to e-mail you but it bounced back as being undeliverable. Yes you can use the adapter. I've used one several times. You probably do need to disable the com port in the BIOS. There's another problem though. The operating system will be looking for a bus mouse, not a serial device. Make a boot disk, you may need it. Boot from it so you know you can reach your cd from the commad line. You may have to reinstall Windows. Boot normally. Open Start/Control Panel/System. You be looking at the device manager. Highlight the mouse and remove it. Open Add Hardware. Let the system try to find it. It should. If it doesn't reboot. It might find the mouse on its own.
