Grub2 fails to install to the MBR of /dev/sdb

Hi
I have recently done a fresh install of Fedora 16. My machine has 2 1TB SATA drives, and came with Windows 7 installed on the 1st drive. I then partitioned the second drive into several partitions; one for /boot, one for /opt, one for /usr/local, 2 for /, and one for /home. I keep the current version on one of the / partitions, and can install a new version of the second. Rather than overwriting the MBR on the first drive, I changed the BIOS to boot from the second drive, and had grub installed there. When I installed F16 and it came to where it wanted to install grub2, it gave me the options of installing on the MBR of /dev/sda, or installing in /boot. Not being sure which drive it was calling /dev/sda, I had it install on the /boot partition. That left me with still booting using grub. I have now modified grub.conf to chain-load grub2, and can boot where ever I want from there. I would like to now install grub2 to the MBR of /dev/sdb to eliminate the grub step. I run the following command and get the error following:

#grub2-install /dev/sdb
/sbin/grub2-setup: warn: Your embedding area is unusually small. core.img won't fit in it.. /sbin/grub2-setup: warn: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
/sbin/grub2-setup: error: will not proceed with blocklists.

Sorry for the line wrap, the above is 4 lines. Below is some information about my machine. If anything else is needed, I will try to supply it.
