cfdisk is AFAIK only used to edit DOS or PC-BIOS like partition tables.
In fact this is a major feature, in that you can attach x86/Linux disks up to your Sparc to examine them and retrieve data.
And viceversa. I had once a case where plugging a Solaris/Sparc hard disk to a PC running Linux for data recovery saved the data and the day (actually, much more than the day). -- Alfredo Sola ASP5-RIPE
