I have an old Dell XPS Gen 2 computer. It supports three ATA drives and two SATA drives. I've relegated this computer to Windows Home Server duty. I currently have three ATA drives installed. I would like to add two large SATA drives and keep the current ATA drives, and continue to boot from the current small ATA drive. Awhile back I posted on Dell's forum and was told if I install SATAs I would have to boot from a SATA rather than the current ATA. Just doing a reality check over here - does that sound correct? Why might it not boot properly from the ATA?
