This a tricky operation or some and not for others. Meaning, it just won't work, period because of h/w. All you can do is try it. that's the best i can offer if you plan to keep the IDE drives. Otherwise, move on to SATA, now. I say this because all those adapter or PCI cards aren't intended to boot from, but if they do they remain the primary drives and cut-out the SATA side. Which is why it becomes tricky. These cheaper adapter just don't always cut it and sorry the OS too becomes a PITA as it wants to work on the originally installed setup. You will need to ghost or clone over and then hope your adapter provides the needed operations to do this. Once done, you can then add the next drive and/or finish the setup. So, you need to try your current primary old drive and using one new drive plus s/w(came with it or you get at support website) -OR- use clonezila to complete this. As you see by my post, it all seems tricky and not for the fate of heart. Also, you're dealing with XP which is a painful OS to work with at times. Now, maybe a good to move on to Win7 and copy only old data over(save beforehand) and see where it goes. Win7 has it own file xfer service feature build-in.
I'm upgrading my Windows XP Pro system to a new ASUS M5A97 R.2 motherboard that has no IDE ports. My current system uses 4 IDE hard drives. The new MB has 2 PCI slots. If I install a PCI IDE controller card, can I boot from my current XP Pro sysyem hard drive? The controller card has 2 ports. Will the MB recognize 4 hard drives? Once I have the system working I intend to clone the OS drive onto a new SATA hard drive. I'll welcome any suggestions.
