This is how I did it.
I downloaded MEPIS live cd from
here..
I read
this guide
I burned an iso image and booted from it and followed the above instructions and installed MEPIS on my new partition.
Once I had a new partition seperate from XP (with MEPIS installed on it), I downloaded SUSE 10.0 and burned it to a DVD and booted from it. The setup let me wipe MEPIS from my partition and install SUSE 10.0 on said partition.
Once SUSE was installed I followed
this to get multimedia running smoothly.
