I had a nasty suspicion that might be the case.  I'm going to be really
furious at 3Ware if it turns out to have gone bad while sitting there
unused for nine months while 3Ware sat there with their thumbs up their
asses scheduling meetings to discuss debating when they were going to
get around to bothering to tell me they'd EOL'd the card.

But I need to at the very least actually get the install disk booted
before I can do that, right...?  The installer kernel should be SMP
ready straight out of the box though, and should Just Work.  Right?


(Sudden thought:  there should still be a basic Solaris 10 install on
the boot disks.  Booting that ought to tell me whether there's any
hardware problem that could reasonably be keeping the machine from
booting the installer.)
