in the P4 system. It's quite a shock to the OS from the P3 when one tries to make a major change like that. One way is to do a repair install of the OS but you will need the full install OS/CD for it to work. More info here.
I have a dell Pentium 3 PC running XP Pro, SP2. A friend has given me an unwanted IBM Pentium 4. I would like to take the hard drive out of the P3 and put it in the P4, and just start working. The hard drive is a Seagate Barracuda 7200.9 Ultra ATA/100 80-GB Hard Drive. I tried putting it in previously but the P4 wouldn't recognize it even though the BIOS recognized the make/model of the hard drive. I imagine this might have something to do with the difference of motherboard and CPU on the new system. Any suggestions?
