My saga continues...

I burned the iso of Debian disk one for sparc, stuck it in the cdrom, 
got the ok prompt and typed:
"boot cdrom"
to which it returned
"Boot device: /iommu/sbus/espdma@f,400000/esp@f,800000/sd@6,0:d File and 
args:

Can't open boot device"

I am not sure where to go from here. Does anyone know if I need to use a 
boot floppy or what?

Thanks
