I now have the /boot part of my whole system. But it would be easy to make a new partition of say 100 MB the first thing on the second hard drive. My question is what do I need to do so the new /boot works?

I did something similar with a dual-boot system:  Windows on the
original first drive, all by itself.  And Linux installed on an added
second drive, all by itself.

While setting up GRUB, you define its root (where /boot/ is) with a
"root (hd1,0)", then "setup (hd0)" which puts the bootloader onto the
first drive MBR, and quit out of the GRUB shell.

[root@bigblack ~]# grub
grub> root (hd1,0)
grub> setup (hd0)
grub> quit
[root@bigblack ~]#

In this scenario, the computer boots, reads the MBR on my first drive,
which starts off GRUB from my second drive.

I believe that you can even set that up from within the GRUB start up
screen.  Just hit the right hot key to get into the command line.  You
can also do it from the rescue disc, so you can get a system working
that's not currently booting.

I know Tim and that is what I use now that works. I have grub at (hd0) and the Linux is at (hd1,5). This works fine so why move /boot?

I am certain that (hd1,5) is about 100 GB up from start of the second drive. And it works.

I thought this whole thread was about this setup not working all the time. What does fdisk -l say about the cylinder range of that 5th partition?

   Well it is the sixth partition. This is (hd1,5) in grub talk :-)
