Hi folks, I need some help. My A4Tech wireless mouse is not working in my P4T-E mobo. I'm running Win 2k with SP2 but I have other computers with different mobos with the same OS and it works fine. Here is what happens with the P4T-E machine: I plug the mouse, restart the computer and all the mice devices disappear in the device manager. No mouse at all. Is it a mobo bug/ Should I update bios? One thing I notice in the boot up screen is something like 'Bios data update incorrect' written. Don't know if it relates to it. Thanks in advance for any help.
