The minimal configuration requires 16 MB of RAM and ~60 MB of disk space.
To install the entire system requires much more disk space, and to run
X or compile the system, more RAM is recommended, as
.Nx
with 4 MB of RAM feels like Solaris with 4 MB of RAM - slow.
Note that until you have around 16 MB of RAM, getting more RAM is more
important than getting a faster CPU.

.It [1]
Sbus ethernet drivers current have a problem with interrupts and
do not perform properly except in extreme low usage conditions, rendering
them effectively unusable.
.It [2]
Access to devices on the secondary PCIIDE channel currently do not work.

.Pp
There are a large number of untested PCI drivers that have never
been tested on UltraSPARC PCI systems that may "just work".
