The installation tools and process as of the 2.1 release are greatly

OpenBSD/sparc can be installed or upgraded via floppy boot images on

improved over previous releases of OpenBSD, and more work has been done

sun4c and sun4m, miniroot images for machines without floppies

with each successive release. OpenBSD/sparc can be installed

(and sun4 machines), as well as network and diskless installs.
