For 4# machine independent notes, look in /sys/conf/NOTES. 5 6# directive: cpu 7# You must specify at least one CPU (the one you intend to run on). Deleting 8# the support for CPUs you don't need to use may make parts of the system run 9# faster. There's currently no special code for the different CPUs. Note also 10# that the cpu declares the family. We may need to add support for specifying 11# particular models. 12cpu ITANIUM 13cpu ITANIUM2 14 15# option: COMPAT_FREEBSD32 16# This option enables the support for execution of i386 (32-bit) programs on 17# ia64.
