BIOS boot partition, 4x3TB disks, and raid, problems with anaconda

   gdisk will seamlessly convert an existing DOS partition table made by say
fdisk, parted, gparted, ... to GPT format on the fly without disturbing the 
any actual parttions ( you may want to back up first though ... ) .  

 Additionally, I have not had any problems getting 3-4 year old standard dumb
BIOS to boot from a 3TB drive . Never tried with UEFI though.
