--- Comment #103 from Gerard Seibert <gerard_seibert at outlook.com> ---
I just updated the BIOS on my system. That version was only one version older
than the new one. Anyway, this is the output from 'dmidecode'.

# dmidecode 3.2
# SMBIOS entry point at 0x6fe8d000
Found SMBIOS entry point in EFI, reading table from /dev/mem.
SMBIOS 3.1 present.

Handle 0x0000, DMI type 0, 24 bytes

Does anyone have any idea if this will correct the problem? I would really hate
to trash the whole system again if this doesn't correct the problem. Also, why
would this problem NOT exist on a FreeBSD 11.x (and perhaps older) system? It
only started with 12.x. I find it somewhat difficult to believe it is solely a
BIOS version problem.
