Questions on RAID 1 - Mirroring

I am trying to setup two hard drives with Raid 1 setup on them. What makes
this a little more difficult is that I am having to setup the raid after the
fact. I already have one of the hard drives running RH 7.0 and the
partitions are like this:

	75 MB		/boot
	256 MB		Swap
	3.8 Gig		/

I want to mirror enough so that if the first hard drive goes bad the
customer will not go down but be able to function from the 2nd hard drive
with little to no intervention. This is very important because we have
customers using the systems up to 5 hours away and they cannot have the down
time. I have gone through the Non-RAID Redhat System to run on Software RAID
howto article but it still fails on boot. I believe from my reading it has
something to with not being able to mirror the /boot partition but I am not
sure. I know that this is possible, or at least it should be but I am not
finding very much comprehensive information on this. As a side note I am
able to mirror the / partition with no problems. But if I unplug the first
hard drive with the /boot partition simulating drive failure it will not
boot (of course). If anyone has had any experience in setting this up or
knows of some good resources for RAID I would be very appreciative. Thanks
for any help
