.Pp
The minimum configuration requires 4 MB of RAM and 100 MB of disk space.
To install the entire system requires considerably more space, and more
RAM to achieve reasonable performance.
.Nx
with 4 MB of RAM feels like
.Tn Solaris
with 4 MB of RAM \(em slow.
Note that until you have around 16 MB of RAM, getting more RAM is more
important than getting a faster CPU.
.(Note
The sparc port does not have functional SMP support in this release.
We expect this to be fixed in the next release, but in the meantime,
.Nx
4.0.1 has working SMP support.

.(Note
Non-Sun SCSI CD-ROMs may have trouble booting any OS,

or otherwise.  Your CD-ROM must support 512 byte blocks for the OpenBoot PROM
to load a file.  Most newer CD-ROM drives support this automatically, and 
many older drives allow you to set it using a jumper.  See
