  My lord, I send greetings. I have a mind to try
FreeBSD-12.0-RC3-i386-disc1.iso,
and willingness to report back my  experience.  The  get-at-able  hardware 
gives:
686 class Pentium 4 (socket 775), 686 class Celeron (socket 370).

  My guvnor, I have zero writable cd media at this time.  I  grabbed  the  dvd 
iso:
FreeBSD-12.0-RC3-i386-dvd1.iso. I can say the boot run its course and  served 
up  a
login prompt with considerable aplomb. The contents of  /var/run/dmesg.boot  can
be
viewed at ` http://dmesgd.nycbug.org/index.cgi?do=view&id=4625 `.
