Randyman...

What about my 2x Optical PATA drives on the Southbridge? Wouldn't that disable them, as well? Also, if I'm not mistaken, the Promise Controller does not respond to any of the primary MoBo BIOS Settings (just the "Enable/Disable" and the "RAID/IDE" mode switches specifically for the Promise Controller). I think beyond those 2 parameters, the Promise essentially has its own BIOS/Firmware that runs inside of the main BIOS (total speculation on my part)...

I also tried looking for info at the Promise website, but they don't seem to supply info or FAQ's for the integrated MoBo controllers (only the add-on PCI cards).

I'm thinking I might sacrafice one of my 300Gig PATA HD's, and do a RAID-0 with one SATA and one PATA (both drives are identical except for the PATA/SATA variance). This means I would be stuck with an extra 300Gig SATA drive with no-where to put it (all of my removeable HD's are PATA's that go through a PATA-to-FIREWIRE bridge board). I guess I could put the 300Gig SATA in my other PC that is on the same LAN, and still use it as an "Online B/U HD" by copying B/U files through the LAN. Decisions, decisions...

I guess I have a few options open - but none are a simple fix (a simple "Disable PATA on Promise" setting would be oh too easy )... Sucking it up would be the easiest "fix" - but that is not my nature

Thanks for the continued input
