Which OpenBSD install image are you using? Are you booting from USB
or some other way?
Just now, I dd'ed the snapshots/powerpc64/install69.img onto a USB stick
and rebooted my TalosII. I see the serial console by ssh'ing to the bmc
and running obmc-console-client. The USB stick appeared as "OpenBSD
install" in petitboot. I didn't find a message saying, "switching to
big-endian OS." The console output, after I selected "OpenBSD install"
in petitboot, was
Performing kexec reboot
SIGTERM received, booting...

Here, the copyright is the first message from the OpenBSD kernel.
Are you not seeing the copyright?
I wonder if your USB stick is bad. If you mount its DOS partition,
you should see 2 files (boot, grub.cfg), and "boot" should be an exact
copy of "bsd.rd" from the snapshot.
A regular DOS-format USB stick would become bootable by adding just 2
files: "bsd.rd" copied from the snapshot, and a small "grub.cfg" like,
menuentry "bsd.rd" {
linux /bsd.rd
initrd /bsd.rd
}
I wonder if your Talos has old firmware, and if old firmware can
confuse OpenBSD. If you pick "System information" in petitboot, it
should show several version numbers. --George
