4# machine independent notes, look in /sys/conf/NOTES.

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

14# CPU OPTIONS
15
16#
17# You must specify at least one CPU (the one you intend to run on);
18# deleting the specification for CPUs you don't need to use may make
19# parts of the system run faster.
20# XXX: On the Sparc64, there is only one CPU type

34# New OpenFirmware PCI framework. This fixes a number of interrupt-
35# routing problems and changes the device enumeration to be hopefully
36# closer to Solaris. Be aware that, because of the latter, enabling or
37# disabling this option may require reconfiguration, and can even
38# cause the machine to not boot without manual intervention before the
39# fstab is adjusted.
