grub can't find config file

[Edwin Olson]

I did a  clean FC4 install to the second disk (hdb) of my x86 machine. 
hda is Windows. During install, I requested grub be written to hda, and 
upon reboot, grub runs.

But grub can't find its config file, so it dumps me at a command prompt.

I can proceed normally by typing 'configfile /grub/grub.conf'. The menu 
pops up and I can boot both windows or linux just fine.

What can I do to make grub automatically find its config file in this 
most obvious of locations? :) Could there be a bug that I'm tickling, 
since the config file is on hdb instead of hda?
