Chainloading worked, Grub 2 didn't.
GRUB Loading stage1.5
GRUB loading please wait...
I thought that Grub 2 was supposed to be smarter than old decrepit Grub.
1023 cylinders or not, sda2 was my /boot from the first time I installed
fedoralinux to some considerable time after I put in the second drive.
Old decrepit Grub handled it.
Why not wave of the future Grub?
Also note that sda2 does not cross the 1023 cylinder boundary.

I'm pretty sure it is Grub 2.
Not only do I have a brand new grub2 directory with nearly 200 files in it,
