Hi George, > I never saw this weird message "CPU not active in OPAL". You have
the same board as me (T2P9S01 REV 1.01, Talos II with single cpu socket). I've
the dual socket board with 2 02CY650 CPU (4 core each) Thanks, I followed your
instructions and it worked! steps I did: - boot with the bsd.sp - got the 7.3
src - apply the diff - build [custom.mp](http://custom.mp/) - "make install" it
result: ... OpenBSD 7.3-stable ([CUSTOM.MP](http://custom.mp/)) #0: Fri Apr 14
15:07:31 CEST 2023 Welcome to OpenBSD: The proactively secure Unix-like
operating system. ... ps.: Sorry for taking long to reply, it was a good
exercise for someone trying to get familiar how openbsd dev works, I was
learning the steps to build the custom kernel, and was short on time. regards,
