Folks, perhaps someone can advise me here. I have built and run many unsupported installs on various TNT (7500 class) machines, so I'm very familiar with the basics. So far all of these have been of Puma (patched to 10.1.5).
I'm now experimenting with unsupported Jaguar, and also with a Tsunami (9500 class), and also with a new Sonnet G4 card (800 MHz, using 7455 cpu, with three level cache therefore). Puzzled by two results: 1. Although I can activate the standard backside L2 cache on my earlier Sonnet cards (G3 750/400 @ 8*50; G4 7400/405 @ 9*45) using Ryan's L2 configuration utility, this does not seem to understand and configure the backside L3 cache as found on a 7455 cpu card. Hence the new card seems to run somewhat hobbled under OS X Puma. Nor does PowerLogix cache control utility understand these cpus yet. Can other people confirm that this is indeed the case? That the Sonnet 800 PCI card is not fully active under OS X Puma? 2. On my test Jaguar installation (Tsunami), the Sonnet 800 card refuses even to start under OS X Jaguar. I installed this OS using XPF 2.2.4 from vanilla Jaguar CDs, then patched it to 10.2.2. BUT, I installed it using the Sonnet G3/400 card, not the G4/800 card. If I swap in a G4/405 card it boots fine, with or without L2 cache configured (since these two cpus have the same backside cache scheme so they are plug compatible). If I swap in the G4/800, the machine won't even bring up raster. Instead , the HDD whirrs and hunts, as if it is seeking something special in its boot blocks. I am concerned that that Jaguar installations may turn out to be cpu specific (or at least cache structure specific) so that an installation built using one kind of cpu can't support other kinds. Has anyone seen anything similar to this? Thanks for any help you can give.
