.Nx*M
\*V runs on Motorola
.Tn MVME147
,
.Tn MVME162
,
.Tn MVME167
,
.Tn MVME172
,
and
.Tn MVME177
Single Board Computers.
.Pp
The minimal configuration requires 8 MB of RAM and ~200 MB of disk space.
To install the entire system requires much more disk space (approx.
600 MB additional space is necessary for full sources.
Double that if you want to recompile it all!).
To run X (clients only) or compile the system, more RAM is recommended.
Good performance requires 16 MB of RAM, or 32 MB
when running the X Window System.
.Pp
Note that you can install
.Nx
\*V
on a system with only 4 MB of onboard RAM, but you will need to use a
VMEbus RAM card with at least another 4 MB to augment the onboard
memory in order to actually install the system.
.Pp
Here is a table of recommended HD partition sizes for a full install:
.Bl -column -offset indent Partition Suggested Needed
.It Partition Ta Suggested Ta Needed
.It /\ (root) Ta "32 MB"   Ta "26 MB"
.It /usr      Ta "200 MB"  Ta "150 MB"
.It /var      Ta "32 MB"   Ta "6 MB"
.It swap      Ta Em "2-3 *RAM" Ta 16 MB

Anything else is up to you!
.item)
.Pp
Note that the
.Nx*M
installation procedure uses a
.Em miniroot
image which is placed into the swap area of the disk.
The swap partition must be large enough to hold this miniroot image
(\*> 7.5 MB).
