The MBR of the second drive is fine.
I've had as many as four distros on _one_ drive, each with its own grub
configuration; the first, in addition to booting something directly.
chains to the others.
Note: SUSE distroes put all Linux systems into one grub configuration. I

one system has even the vaguest chance of updating its menu properly.
