Lou and I did some research.
Lou contacted Polaris. I finally got through to Sun.
Here is the story:
The first run of Ultra 5/10 motherboards with 24bit on-board graphics
got shipped out with a capacitor soldered on backwards. This problem
was spotted quickly, and not too many machines shipped with the problem.
Machines we have that are affected by this are Ultra 5's and Ultra 10's
that have the 24 bit on-board graphics, shipped from Sun before December
17, 1998 are at risk.
Since this is due to a capacitor soldered on the wrong way, you'd only
discover the problem by waiting for the capacitor to blow out.
NO SOFTWARE VISIBLE PROBLEMS are related to this.
Also, it doesn't matter if its a 333MHz machine, or an Ultra10 with
Creator graphics, if it has the right vintage of motherboard, it is at
risk.
How do you identify the machine?
The serial number tag has PGX24
The serial number FW followed by an 8 digit number LESS THAN
85200000
There is NO tag WSS200#11942 on the back panel of the chassis.
The third item is significant. Presense of that tag means that someone
has ALREADY looked at the machine and fixed the problem if it is present.
Lou and I are now trying to figure out the best way of identifying the
FEW machines that need new motherboards.
Share and enjoy,
