# This file contains machine dependent kernel configuration notes.  For
# machine independent notes, look in /sys/conf/NOTES.

# This directive is mandatory.  It defines the architecture to be
# configured for.  In this case, this kernel is for a machine using
# UltraSparc processors.

# CPU OPTIONS

#
# You must specify at least one CPU (the one you intend to run on);
# deleting the specification for CPUs you don't need to use may make
# parts of the system run faster.
# XXX: On the Sparc64, there is only one CPU type
cpu		SUN4U
