I have tried to do that and failed, but after I gave up and booted back to 
F10, I found that diskdrake did not actually use the /dev/sdd3 and up 
partitions that I told it to, translating
 /dev/sdd2 into the extended partition, and then continueing the sequence not 
at /sss/dev/sdd3, but at /dev/sdd5, so the last one is /dev/sdd10, but its 
actually the 8th partition.  Confuuzzin ain't it?

No, I didn't let it install the boot loader at all.  However I've found, from 
the /dev/sdd10/etc/fdisk, that it also left out a partition I need, so I'll 
reinstall again tomorrow & see if I can 'get it right'.

Can I let it install to the mbr of /dev/sdd without confusing the one on 
/dev/sda?  I have added the two newer drives to /dev/sda1/grub/device.map now, 
and I'm hoping that will be sufficient for grub to find the new boot files 
(once they are installed that is)

Which I may have to build, all I got from the install was an obviously wrong 
/boot/grub/menu.lst-example.  And yes the new drive does have a /boot 
partition (as does the current F10 install) where all the normal files live.  
But that new /boot/grub, on /dev/sdd1 is, except for the menu.lst-example, is 
otherwise empty.

Many Thanks for the prompt response.

Cheers, Gene
