raid arrays are real hw raid on the 3ware card, and show up as very large 

I was trying to install to a single drive (non raid) in the earlier messages.

There are no fake raid arrays, just the hw raid arrays and the two individual
disks, which show up as sda and sdb (very large 2Tb disks) and sdc, sdd which 
are the two single disks.

The install never runs, it just hangs as I described, so I have nothing on
any of the disks...

Not a blank screen, a screen full of hash with an X cursor which changes to 
the arrow, but I cvan't see anything in the the hashed up screen.

I'll look for the xorg.conf details in knoppix, but how do I use those to do 
a centos graphical install?
