How do I determine the answer to Richard's first question?
[...] "The easiest way to find out if you are running UEFI or BIOS is to look for a folder /sys/firmware/efi. The folder will be missing if your system is using BIOS."
That's on a running system, by the way.
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?
