[scyld-users] Beoboot failure

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.
