Problem configuring RAID 5 with Windows Server 2008

raidwindows-server-2008

I have 8 1TB Drives in my machine, set up as RAID 5
The raid controller is a 3ware 9650 SE 8LPML

I'm not sure if its important, but the mainboard is:

As far as i know, i've configured a 6TB array – in the menu when i pressed ALT + 3 during the boot phase.

I then tried to install Windows Server 2008 on this, to no avail
It said it couldn't see any drives etc…
I tried a few drivers, none of them worked. All said invalid drivers.

Eventually, I gave up, and installed Windows Server 2003 x64 – which, after messing about with drivers and a usb floppy drive, went in ok.

However – i could only see the volumes in the device manager -> disk management thing, and even then, they were split into 2 or 3 chunks….
Is this something to do with converting to GPT? if so… how do i do that?

My problem is, I would really like to install Windows Server 2008
Anyone have any idea as to what driver i need? Is it a problem with my BIOS or this 3ware raid controller?

Alex-

Are you trying to boot to the 6TB array or just use it as a data volume? You would need to partition it with a Guid Partition Table (GPT) in order to address that much space, and you can only boot to a GPT volume if you are using EFI instead of a legacy BIOS (not sure what that Tyan board has... EFI is still pretty uncommon). Some more information here:
