" but how do i tell the minimum linux to go to a window manager ect?"
I don't use boot floppies so offhand I am not sure exactly where you are in the process when you ask this question. If you have logged in as root then you can type in: kdm. If you have logged in as either root or user then you can type in: startx.
You can also try using YaST to make a boot floppy. Maybe it will make a smarter one. YaST can probably make a bootloader floppy which is more convenient than a boot floppy.
The way that I make a boot floppy is to use lilo which is more complicated than the above methods:

The only reason I have boot floppies on hand is for when I destroy lilo on the MBR. Most people find useing a bootloader, either lilo or grub, on the MBR more convenient than using a boot floppy.
