This is mentioned in the manual page.  The two real memory statistics
total real memory used and active real memory.

At a minimum:

1.  Shutdown the system.
2.  Install the memory.
3.  Boot.  You may want to run the console commands that check the
    amount and run a memory to make sure that everything is ok.

The physmem parameter in the configuration is used for setting some
table sizes (page tables, etc).  At one time the only interesting
values that I could see where less than 64 KB and greater than 64
KB (I don't remember which equal belonged to).  You'll probably want
to change physmem to reflect the actual amount, but it isn't absolutely
necessary.

Update the "config" line in the configuration, rebuild and reboot the
new kernel and edit /etc/fstab to include a line for each additional
device.  The format of the lines is:

/dev/block-device::sw:0:0:ufs::
