The only way around the limitation is to purchase a 3rd party i/o card and install the drive on it. You should be able to boot from it. I have a similar setup on a 2001 Quicksilver, a 250gb SATA drive using a SATA i/o card. I also still use the original IDE ports with (2) 120gb 7200rpm WD drives in RAID 0, for backup.

Is there way to test it's functionality. Also I know there is size limit on HD's on a Graphite G4 is there a way around this. When I try to format it the task bar gets so far then stops. Any advice would be appreciated.
