I'm curious about a few things...
The Power 3 in the 170 is running in 32 bit mode I assume?
Also with reference to the PPC linux system running on the Beta Power 4
is this also in 32 bit mode?
The Power 3, RS6000-III and Power 4 are all 64 bit chips from what I
understand and IBM's literature makes me think that AIX is indeed running
in 64 bit mode with the ability to run 32 bit apps.
From what I have heard, NT running on the Alpha is in 32 bit mode. Is
Linux running on the Alpha also 32 bit? I would assume Tru64 Unix is
running in 64 bit mode on the Alpha....

Linux runs in 64 bit mode on the Alpha and the SPARC64 (UltraSPARC).
Linux runs in 32 bit or 64 bit mode on the MIPS64.

Hi Bob,
That's correct. The 64 bit PowerPC Kernel is a work in progress at the moment.
Also with reference to the PPC linux system running on the Beta Power 4
is this also in 32 bit mode?
That is also correct.

understand and IBM's literature makes me think that AIX is indeed running
in 64 bit mode with the ability to run 32 bit apps.
Actually the AIX kernel runs in 32 bit mode, however it has the ability to run
64 bit apps.

Alpha Linux is 64 bit.

All of the PowerPC chips from the G4 back to the 601 are 32 bit.
The new Power3-II and RS64-II (only found in IBM machines) are 64 bit but
have the ability to run 32 bit programs including the OS.
Someone else answered the question concerning alphas and sparcs. In the
intel world, everything from a 386 to the newest pentium 3/xeon/etc are
32 bit. The yet-to-be-released merced is 64 bit.

32 bit. Call me the day an affordable 64 bit machine is available (I mean
for home user/hobbyist). No Apple machine has ever had a 64 bit processor
to start with.
Note that actually running the kernel in 32 bit mode makes sense
on 64 bit processors since the code is smaller (building addresses is much
easier and does not require a TOC) and there are fairly simple and cheap
MMU tricks to access all memory if needed (playing with segments but this
can be kept local to a given CPU, so no locking is necessary).
