Sadly yes, there's a known issue with psu in fuels. I have one that went
kaboom after 20 minutes and lies waiting for a psu since months (and will
lie that way, I guess. I'm looking at it in a sad way near daily...).

Long story short, Fuel psu were made by 3 different brands, and each of them
had ... longevity issues... in what we could say being revision 1 to 3.
>From 4 upward (and if I'm mistaken , at worst was from 3 upward) they tend
to be resistant.

Exploding issues aside, those psu are not standard and have a chip doing
some mumbo jumbo inside (all lines are monitored, by example). That chip can
.. erase itself... ( in the upper mentioned revisions, for sure ). There are
no known dumps of the chip firmware.

My coworker has a Fuel sitting on his desk here, I'm staring at it. There is
some sort of failure with mobo or power supply. He has a spare motherboard
for it, but I think he said it's PSU. Prob caps, is there a known issue with

Also, I used nfs to get to ISO data of IRIX 6.5.2x updates for my Octane and
it worked fine. Flashbacks to my days as a sysad @ NASA in IRIX land, and as
a huge SGI fanboy...
