<p>I did the same thing with a cast-off IBM X3350 series system.
Worked fine, but the box sucked so much power, that it now spends
most of its time powered down. For it's time, it was plenty fast
and a great platform to run Tops-20 on.<br>

<p class="MsoNormal"> A2RTR will be down tomorrow (Monday)
for a couple of hours sometime between 9AM PDT and 3PM.
It’s not my doing – PG&E is replacing a transformer
and the power will be off. I have battery backup for some
of my equipment, but not A2RTR. Sorry.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> It’s also going to have to go down
sometime again, maybe next weekend, so I can replace a
disk drive that’s failing. I bought two identical drives
and plan to set up a RAID 1 array this time. If anybody
has set up a software RAID on Ubuntu, using the md driver
and mdadm, for the system drive and you have advice, let
me know. Espcially if you managed to make both of the
drives bootable.<o:p></o:p></p>
