.Pp
The minimum configuration requires 4 MB of RAM and 60 MB of disk space.
To install the entire system requires about 260 MB (not including swap).
To install the X window system you need at least 295 MB (not including 
swap) and 8 MB RAM.
.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.

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

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
