Okay, so, umm thank you for confirming that this is a "known fact". Not 
sure where it's known since it isn't explicitly stated in the public 
parts of Ryan's site. (Alas, I've mislaid my login for the support 
forum, so I guess I'll have to pony up for another $10 - hey ho.)

But that's not the real issue. Which is:

That using the Tsunami system with a Sonnet 800 card installed, I have 
now tried to install Jaguar- to a freshly-formatted HDD - first using 
XPF v2.2.4, and then using Sonnet's own variant v1.2.5. In each case, 
the preliminary parts of the procedure proceed normally, but on restart 
the system hangs before it will bring up raster.
The same system works fine with Puma. The same system works fine with 
earlier cards using the 750 or 7400 cpus. We're not even getting into L2 
cache config territory here - which happens a long way into the boot 
process.

So I've got an apparent incompatibility between:

a. My Tsunami Mobo
b. Jaguar
c. Sonnet's G4/800 PCI card
d. The particular SCSI HDD I'm using.

If I change either b or c I have no problem. Now I'm trying to find out 
whether changing a or d will cure it too. Right now, I'm suspecting the 
firmware of the Sonnet 800 card as being the guilty component.

According to the ReadMe for PowerLogix Cache Control v 1.2, it isn't 
compatible with the later G4 cpus which use L3 cache, so I don't know 
which version you are using.

Ah, yes I do. I see that there's a new version called 2.1, which can 
deal with L3 caches. Beta. Very Beta. Okay, I think I'll pass on that today.

I'll post if I get a more definite diagnosis.
