# This file contains machine dependent kernel configuration notes. For

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

# 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 Alpha, CPU types are never used. This list also does
# not include newer CPU types that are supported such as the EV6.
