I have an old P133 and the mouse is not working. The mb manuall calls it a 586 PCI All I/O Green & PnP Mainboard Intel Triton 430 VX PCI 597. I have clean installed both win 98 and 95B and still no mouse. The cursor is there and on start-up I get the No mouse detected screen but the serial mouse is not detected. I have tried different serial mice but no go. Can anyone give me a clue as to how to get a mouse working on this.thanks
