--- Comment #37 from Paul Telles (Starcat) <tellesp2002@gmail.com> ---
I encountered the same issue on an IBM server.

# dmidecode -t system
# dmidecode 3.5
# SMBIOS entry point at 0x7e7bf000
Found SMBIOS entry point in EFI, reading table from /dev/mem.
SMBIOS 2.7 present.

Handle 0x0015, DMI type 1, 27 bytes
