Well here goes, i am installing a new Maxtor 7200 RPM 80GB hard drive into my IBM Aptiva P2 450Mhz computer. I physically mounted it in there with no problems, attached the ATA connector and power cable. When i went to boot up the system it came to the aptiva screen, then beeped once and brought up this message : "0130668 KB Memory Good 8603. PS/2 Pointing device error or not connected"I went into the setup and the system did locate the new hard drive and all other hardware, but has an arrowing next to pointing device, which says none. I checked up on the IBM site to get some help and all it says about error 8603 is "system board". I have no idea what this means, could anybody point me in the right direction as to what is wrong ????
