I installed Gentoo and I want to dual boot the two distros. Well I setup Grub from Gentoo and it will boot Gentoo just fine, but I've ran into a problem with Mandrake. I believe that I'm not pointing to the correct kernel. So does anyone know what kernel Mandrake 10.1 AMD64 Edition run from? Else how can I find it? I see like 3 possible kernels. vmlinuz.... kernel<version>.4mdk and a Kernel<version>.

Bonus points if you could post the setup for grub. It's on HDB. Boot is HDB1, Swap HDB2, Root HDB3

In case I get it wrong no points to be awarded, eh? what not even half?

the mbr of gentoo has grub in it I assume?
so you edit your gentoo /boot/grub/menu.lst or /etc/grub.conf file so

title mdkk1
root (hd1,0)
kernel /boot/vmlinuz root=/dev/hdb3 ro
initrd /boot/initrd.img

don't have gentoo so assume its initrd.img could be .gz and its highly likely you use a initrd.

2) redo title mkdk2
replace vmlinuz with vmlinuz.....4 etc

3) redo title mdkk3
replace vmlinuz with vmlinuz.....?

4) However your first entry vmlinuz is a link file to the real kernel. If you can boot into mdk the try this in a terminal

ls -l /boot
should bring up a list of files and any links in your boot folder.

and you may have to edit your initrd line for each mdk title as well
