That’s the configuration I used to test this recovery procedure.
Chances are, of course, that your configuration is slightly different than this. If you are running Linux on an Intel-based system, this procedure will work for you without modification. If you’re running Linux on a Sparc system, you will need to use a different boot floppy and silo instead of lilo. If you are using an Alpha version of Linux, your options are a bit more complicated.
