a single kernel can run on ALL SUPPORTED SPARC machines. Whereas

SunOS and Solaris have always had separate 'kernel architectures', i.e. sun4,

sun4c, sun4e and sun4m, the same 'GENERIC' OpenBSD kernel will run on all the

supported models.

Most of the problems with OpenBSD/sparc are believed to stem from the wide

Booting off the CD provides a small ffs filesystem with a GENERIC kernel with

drivers for all supported devices found on SPARC machines.
