Yes, that is correct. If David is leaving off the "-f", it is possible
that the PROM is booting sash first, and letting sash boot the kernel.
On the other hand, David's Indy does have the latest Indy PROM, so it is
possible that the PROM developer dropped in ELF support. We can't assume
it is available on an Indy, so we let sash do the work.
I checked on the PROM source, and the recent PROMs, such as what David
has, do indeed boot ELF binaries directly. That is, both ELF and ECOFF are
turned on in the recent Indy PROMs.
