- 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::
