More information on my dual-boot problem. I first installed the 64bit . Since I used the default settings it installed in the MBR. Next I installed the 32bit . This also went into the MBR. After this I could only see the 32 bit install. I used the install/repair to get the 64bit visable at boot. I edited menu.lst and added the 32bit install . image = /boot/vmlinuz ###Don't change this comment - YaST2 identifier: Original name: Linux32### label = Linux32 initrd = /boot/initrd optional root = /dev/hda7 vga = 0x317 append = "splash=silent console=tty0 desktop resume=/dev/hda5 showopts" When I try to boot this the log shows /dev/hda7 but acts as if it is still loading the 64bit. uname shows x86_64 and I get lots of load errors that go along with this. When you install the loader defaults to MBR. There are other choices /dev/hda* . There is no explanation of why or when to use these options. There are also additional selections on saving to MBR and also no real explanation of when to use them. Both installs are really there but I seem to be able to boot only one of them.
