got bored and used the Terminal to see if my desktop PC's are UEFI or BIOS.

[Moltke]

today i was just surfing google and wondered to my self, just for fun, if my desktop PC's are either UEFI or BIOS , found this to copy and paste int toe terminal , without the quotes

"  /sys/firmware/efi "

if a desktop PC is NOT UEFI , it will say something like " bash: /sys/firmware/efi: No such file or directory" , which would mean that both of my desktop PC's are bios.

am i right ?. just asking to make sure, i know how to get into and look another way , just wanted a quicker way to tell, ha ha . i like playing with the linux terminal ......

hugs

Running that command in my laptop gives the same result but then this is a UEFI system. As reported by inxi:

Code:

inxi -Mx
Machine:   Type: Laptop System: Hewlett-Packard product: HP 2000 Notebook PC v: 0888110003305910000620100
           serial: <root required>
           Mobo: Hewlett-Packard model: 188B v: KBC Version 69.17 serial: <root required> UEFI [Legacy]: Insyde v: F.34
           date: 05/22/2013

But

Code:

sys/firmware/efi
bash: /sys/firmware/efi: No such file or directory

If I understand it right the /sys/firmware/efi command only tells you whether your system/pc is booting in UEFI or BIOS mode, the laptop is configured to boot in Legacy mode - BIOS -  cause I find it more easy but it had Windows 10 in UEFI mode only.  So, maybe your PCs are UEFI but they're configured to boot from BIOS since your systems can either boot from BIOS or both UEFI and BIOS. I might be wrong though. Maybe someone like [member=5916]trinidad[/member] or [member=2]Jerry[/member] can provide a better answer cause I honestly am quite confused now lol
