That's interesting. Is the presence (or absence) of /sys/firmware/uefi
related to 'UEFI is supported' from dmidecode?
$ sudo dmidecode | grep -i -E 'uefi|bios'
Getting SMBIOS data from sysfs.
SMBIOS 3.1.0 present.
BIOS Information
BIOS is upgradeable
BIOS shadowing is allowed
BIOS boot specification is supported
UEFI is supported
BIOS Revision: 1.1
That is, is it possible UEFI is supported, but UEFI is not used? Is
that even possible?
