Good point. I will do that. The first time around local impi is useful
to change the password and DHCP etc. THat's why I had to load those

Hmm, the lack of a BIOS-mod standard is unfortunate. Maybe it will be
there sometime!...shouldn't this be an enterprise-level concern not
just HPC? I mean what if you have 200 Windows machines and wanted to
turn hyperthreading off in the BIOS. It still boils down to some sort
of standardized interface to change it remotely and automatically.
Unless the admins change those manually.....

I know about SOL but what's the "bios-serial-redirection". Is that the
same or a different system?
