In the past, I never had to install grub to sdb.  As long as grub is
installed to one drive, I can boot a OS from any drive.  I did this when
I used to have Mandrake and Gentoo installed.  I had Mandrake installed
on sda and Gentoo on sdb.  I only had one /boot partition which was on
sda1.  It had the kernel for both Mandrake and Gentoo in it and sda1 was
used for both.

So, has something changed that if I want to boot from a second drive I
have to install grub to its MBR first?  When the BIOS finishes and loads
grub, doesn't it always load from the first drive?  If that is true,
doesn't it ignore the MBR on the second drive?  It can't load both MBRs
right?

This isn't making sense.  I have done this many times in the past with
no problems but now something is different.  I need help figuring out
what.
