Not that I know much, but the version should be 29czX, where "X" is
something like 3 or 5 (I think 5 is the latest). Pentium M is essentially a
Pentium 4, so definitely IA-32. The x86_64 is the AMD64 architecture
(cloned by Intel as EMT64). (How did you end up with a mobile chip in a
server, anyway?)

Hi,
I am running v29cz of Scyld. Are you asking what version of beoboot? It is
from an iso image created from beosetup.
I am running 32 bit on a Intel Pentium M (is that x86_64 or IA32?)
Where do I change the TKM delay? Is that on the master before I create the
ISO image?
Thanks! As you can tell, I am lost.

What version are you using?
Are you booting from the distribution CD, or an "iso image" created from
Beosetup?
Are you running on a x86_64 or IA32?

Hmmm, this appears to be a routing problem.
We have seen a similar problem once before in the quick-remaster case,
where the old default route prevents a new route from being added, even
though the interface was shut down. (This is a kernel routing bug that
can be worked around by explicitly deleting the old default route.)

The parameter 'fatal_delay' should set that timeout, and the default is
normally 120 seconds. The only five second delay is in Two Kernel Monte,
and that shouldn't be called. (FYI: The TKM delay may changed with the
'bootmode' flags. The upper 8 bits specify the delay in seconds before
switching kernels. This is pretty much useful only for
debugging and developers, and isn't likely the delay here.)
