for your first question, edit /etc/securettys.
add what it is not, it should be like this:
/dev/console
local:0
:0
host:0
host.your.domain:0

You can use the command "swapon -s" to see the ammount of swap space
available
To add swap space, you must first have more disk space. The command
"disklabel -r [disk]" should help see what partitions (if any) you have
free.
Here's an output from a disklabel I ran on my system
#disklabel -r rz0
<Snip snip snip>
to install swap files in /etc/fstab type "swapon -a"
if you don't have any free partitions, you can re-partitioning your disk
(see the man page on disklabel) to increase the swap partition.

You could go either way on this, as long as you have enough swap configured.
Eager (conservative) swapping will require an additional 512 MB of swap
configured on your 512 MB system, in order to provide your users ths same
amount of virtual memory as lazy swap. I would probably take the 512 MB
hit and go with Eager swap (and not just because I work for a computer
company).

swapon block-device
Digital UNIX supports two local read-write file system formats;
UFS and AdvFS. About the only remotely interesting
UFS commands are:
newfs - make one.
fsck - check one.
dump - backup one.
dumpfs - print all the internal data structures.
tunefs - Change what little can be tuned.
AdvFS offers a much wider set of features and you
can read the advfs manual page for more general
information.

3. When the system runs out of page/swap space in lazy
mode, it kills off idle processes so that the less
idle ones can be paged out. This is usually a bad
thing. Unless you can predict how much page/swap
space you need and provide that much, don't use
lazy.

4. ULTRIX is a 4.2BSD derived UNIX operating system that
runs on VAX systems and MIPS systems that we sold before
the Alpha family. ULTRIX used the same fast file system
used by Digital UNIX, so it has code to recognize the
ULTRIX partition table. You have a disk with one. The
CDROM distribution is a common place for this appear.
