I presume of the second os?  In which case

rootnoverify (hd1,0)
etc etc

Yuppers.  The current grub install is on the first sata drive which udev marks 
as sdb, sda being a PATA drive, and up till now the device map only had a 
reference to that drive, is there something I need to do besides add the next 
drive to the device.map?  Like this:

# this device map was generated by anaconda
(hd0)     /dev/sdb
(hd1)	  /dev/sdc

I added the (hd1) by hand.  Is this ok, or is there more?  I'm a bit leery of 
re-running grub-install, it has eaten my lunch at least once.

Thanks, Norberto.
