    First BOIS. It is all done automatically and both settings are on 
"auto". I can find no way to set them otherwise.

As you see I call grub for the new f7-64 bit with chainloader. It looks 
like:

#boot=/dev/sdb
default=0
timeout=5
splashimage=(hd1,2)/boot/grub/splash.xpm.gz
hiddenmenu
title Fedora (2.6.21-1.3194.fc7)
        root (hd1,2)
        kernel /boot/vmlinuz-2.6.21-1.3194.fc7 ro root=LABEL=/ rhgb quiet
        initrd /boot/initrd-2.6.21-1.3194.fc7.img
[root at k5di grub]#

This is odd because to get the grub.conf on the f7-64 I had to mount -t 
ext3 /dev/sdf3.

A lot does not make sense. But it does work.
