[CentOS] Raid Cards

Just as an FYI, I just did a hexdump of both /dev/sda and /dev/sdb on a 
machine I originally installed as 4.2 (and without manually grubbing) 
and both drives look like the first sector has something boot related on 
them, with text like:

Loading PBR for descriptor 1....done....failed....Bad boot flag... 
active partitions...PBR load error...Bad PBR signature........

So I guess the installer got it right.
