Rescue Floopies and Kernel Compilation

I'm attempting to recompile my kernel on SuSE 9,1. The last time I tried this I ended up messing up the system and having to reinstall. So, if I go into Yast and create a boot floppy, and then I mess up a compiled kernel to the point where my system won't boot, I can get it to work with the boot floppy, right? Just thought I'd run it past you guys... Thanks. Ben
