Greetings! 
have been using openSUSE for many years but never installed 2 linux distributions, so I thought of doing that on separate hard disks, one for 32 bit and another for 64 bit (all on ext4). Disk boot order - sda and then sdb.
So at first i upgraded 11.4 64 bit with 12.1 64 bit - fresh install, enabled MBR as well as the boot partition while installing and created a separate boot partition for it (sdb5) and root partition on sdb1 and everything worked like it should. Then, on installing 32 bit openSUSE on sda6 (root), enabled MBR and root (didn’t create any separate boot partition for it), and since then, only the 32 bit openSUSE boots and booting the 64 bit doesn’t work… on playing around a bit i got it to work in a way that now it boots to 64 bit but internet doesn’t work and a lot of error messages are displayed while booting… like emergency fsck mode etc. if someone needs to know, i will tell what exactly that is.
Can anyone tell me how to configure menu.lst in a way that both of them boot normally. Below, you can see the contents of menu.lst for both 32 bit and 64 bit
Thank you

For the new kernel it try to figure out old parameters. In case we are not able to recognize it (e.g. change of flavor or strange install order ) it it use as fallback installation parameters from /etc/sysconfig/bootloader
