Getting there, but still stuck.

I ran /sbin/grub

At the grub> prompt, I ran

   root (hd1,1)

because the kernel is on /dev/hdb2, and I am led to believe that grub 
always starts at 0.  Then I ran

   setup (hd1)

The command seemed to work, but I still can't boot, because hdb (or hd1) 
is not the boot drive.  Do I change this in the bios or with cfdisk?
