I would like to set up CentOS on 4 SATA hard drives that I would like to

only see raid 0, 1, 5, and 6.
Even when I tried to set up raid5 or raid1, it would not let me put the
/boot partition on it, and I though that this was now possible.
Is it possible for me to set up the configuration I'm looking for?

Cannot speak to raid 10 but have been running 4.4 an 5.0 with raid 1
and /boot partition on md0 for some time. Have not seen the issue you
refer to.

Well as far as Raid10, it's not even an option for the installer. If I
do select raid1 for the entire array, I only get the space of 3 of the 4
drives, and the installer still complains that I cannot put boot on a
raid system.
Is there a how-to somewhere on getting this to work?
I don't know if the installer will let you do it, but you are supposed
to be able to create RAID1 devices, then stripe across them by using
those md devices in a RAID0. I'm not sure if there is any advantage to
that over using LVM to combine the RAID1 devices though. Personally I
prefer to use RAID1 and deal with the space on separate mounted
partitions since it permits recovering the data from any single drive
but if I had to have a larger chunk I'd probably put /boot on a RAID1
and the rest in mirrored partitions combined in LVM.
