Did you generate one for 10.5?

You could copy from that partition to SL.
Also, if you dont flag it to 32bit, it will try to boot to 64.
the -64 flag you wrote is for 64bit.

try with arch=i386

I tried SL before in with 10A380, and I got it to boot a couple of times with -x flag

I am also about to try, but I have am trying to find info if dual booting Leo and SL actually works or not, because I read around here that it is very dodgey to have two partitions with Extra folder (Chameleon)
