 =C2=A0Hi all,<br>
 <br>
 =C2=A0&gt; I have a Sun Ultra 5 with a UltraSparc II+ 360MHz and 256MB of R=
 AM.<br>
 =C2=A0&gt; I burn the ISO to a CD, put it in the machine and at the openboo=
 t prompt I run &#39;boot cdrom&#39;. The bootcode loads up and some kernel =
 messages can be seen.<br>
 =C2=A0&gt; At one point though, when the &quot;&quot; is printed on console=
 , the screen goes black, with all monitors tested reporting no signal, the =
 keyboard stops working (status lights dont work, Stop-a doesnt work) and I =
 can hear no seeking noises from the CD drive. I know it works because I use=
 d it to install Solaris multiple times and it always worked. The serial con=
 sole doesn&#39;t print anything when the screen goes down. I have a friend =
 with similar specs (512MB of RAM instead of 256, everything else is the sam=
 e. even the HDD model) which has had the same exact problem.<br>
 <br>
 =C2=A0We netbooted a custom netbsd-9 kernel, with updated machfb from curre=
