Re: Motherboard replacement

Ah, the good old days of MULIC tapes. Don't forget FULIC's - Feature Unique Licensed Internal Code.

What version of the OS are you on?

Way back on AS/400's there used this thing called MULIC or Model Unique
Licensed Internal Code.  And you used to order it for your particular
system.  And the CE's used to have "Gold Copies" of the OS which could run
on all systems.

Jump forward to iSeries.  I think with V5R1 this was no longer the case.
Instead there was license keys instead.  You'll find this with WRKLICINF.
These are almost always tied to DSPSYSVAL QSRLNBR.  They may also be tied
into the number of processors, etc.
Now, is the QSRLNBR stored on the motherboard?  IDK.  I would check the
service manuals for how to replace a motherboard.  They do occasionally
need replacement and the customer should not expect to have to deal with
licensed key changes.  So maybe they outline how they handle that there.
