It will be necessary to install additional memory on 6386 and 6386SX WGS
processors to bring the system total up to a minimum of 4 MB. It may be
desirable to install additional memory on all models to increase the total
system memory beyond 4 MB. Instructions are provided for adding memory
to all configurations.
