Sparc 2.6 booting problems

[Ashley M <ashleym_(_at_)_geocities_(_dot_)_com>]

I have an old SS2 that I'm trying to load OpenBSD on but I'm having problems.

I tried booting off the CDROM (boot cdrom 2.6/sparc/bsd.rd)

Bad magic number in disk label
Can't open Sun disk label package
Can't open boot device

I tried booting off the floppy (boot floppy)

Can't read disk label.
Can't open Sun disk label package
Can't open boot device

I had Solaris 7 on it before so I tried dd'ing floppy.fs to the boot sector 
of the hard disk and that just stalls during loading.

Please help me.
