[CentOS] sda of CentOS 4 and hda Windows dual boot possible?

You don't have to mess with grub's device map. You can do it all from
the windows section in the config

title Windows
        map (hd0) (hd1)
        map (hd1) (hd0)
        rootnoverify (hd0,0)
        makeactive
        chainloader +1

At least that's how I've got it set up in the office. If there's some
arcane reason for this to be a bad thing, I'm all ears.
