[Nubus-pmac-users] l2cr setting (was: Re: Yellow Dog on PM 7100)

[Daniel G. <da...@gi...>]

It turns out that my advice in my previous message was, and is, applicable
to the Crescendo/PB for the PowerBook 1400, but not the Crescendo/NuBus
for other machines. In this message, I am continuing that for the benefit
of others. Make sure you do a Custom Install of the current Crescendo
software, v2.3.1, and select all the checkboxes:

I referred to GrabL2CacheSetting, not L2CacheConfig.

Do not use any Extension (INIT, Startup Document) for the upgrade card
that is not from your upgrade's manufacturer. Also, make sure any such
Control Panels are not in your Control Panels folder, nor in your System
Folder. From the download links I provided, use only the application, and
do not touch any of the controls; just examine the current cache setting.

That's unfortunate. Did both versions (1.4b2 and 1.5) say that? I can look
around for version 1.3 if so.

See above.

Is this with the G3 working, i.e. with Metronome and/or Apple System
Profiler reporting a G3 with cache?

There is significant risk for hardware damage in using any l2cr value that
did not come from your own machine. IMO, the website should not be making
suggestions for the value, and should give this warning, with instructions
on how to get a good value.
