Hello, I have two hard drives, one of 160 GB ATA and the other 40 GB ATA. The first one is loaded with Windos7 and is the primary. The other one is having XP/SP3. My problem is every time only Windos7 boots up. If I want to boot XP I have to physically change the jumper. So I want to see that I can choose the OS while booting without physically changing the jumper. Is it possible?
