So I continued with the dtb option. >=20 > dtb missing is *correct* with ACPI :) Yep. But: A) The older FreeBSD got as far as did using dtb, not ACPI. (Not that I'd tried ACPI then.) So my best evidence of progress was with dtb. B) It looked like FreeBSD materials were reporting an error and possibly stopping because of it. Not being familiar with what to expect beyond what I was seeing, I went with dtb after that message showed up. >>> You can also enable verbose boot, which might show a tiny little = more detail before the hang, but >>> since we don't get to --<BOOT>--, I am not optimistic. >=20 > Yep, not getting --<BOOT>-- pretty much always means the serial = console is not configured correctly.

Thanks. That gives me another direction to try. What is the distinction between the two .bin files? Should I try both even if the first I try works? Is there something of interest to be learned? =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
