Am I wrong in this assumption and switching between emulation > modes should not affect booting? Disclaimer: I probably don't know what I am talking about and am not familiar with the various modes of the Dell RAID controller etc. Why would you expect it to affect booting? I suspect that the machines BIOS makes the RAID available no matter what the mode and that the boot happens on the "bios" disk (through a "bios" interface). Again, this is not my area of knowledge but that is what I am guessing. Chad --- Chad Leigh -- Shire.Net LLC Your Web App and Email hosting provider chad at shire.net
