Why don't cell phones have BIOS? (lemmy.eco.br)

Why, instead of safely entering a BIOS setup, does the cell phone brick when installing the Custom ROM wrongly? Wouldn't this protection be better for users? I mean, this could be done through ADB.

Also, do you think it's possible that this way of doing things will come to the computer, with ARM hoping to gain a good share of the market and all?

I think you just gave me a wedgie because I thought UEFI was the same... But reflecting, I don't think I have had to use the BIOS since I used Windows 98...

Bios died out around 2010. It lasted a good long time. Your could argue a boot menu is bios and you’ve probably interacted with that at some point.

Also nobody stopped calling it a bios. Every motherboard I’ve owned with a UEFI has called it a “UEFI bios”.

I switched to a Linux OS in '08 and haven't really paid attention since. I've done a little partition work but I'm no superuser.... I probably have a UEFI and don't know it. My days of using the bible are gone haha

That's not a guarantee.

UEFI uses GUID Partition Tables (GPT) instead of a Master Boot Record (MBR) and needs an EFI partition.

I personally recall Linux in 08 had pretty abysmal UEFI/GPT support. I'd say support didn't become as good until about 2015-2016ish.

So you very well may still be using traditional MBRs if you haven't really changed your setup.

Especially since a lot of UEFIs come with a compatability layer to mimic BIOS and allow some backward compatability.

Late reply since I've been in the field - I no longer have to worry about partition space for kernels, that is nice. Using mobile rn but I will look when I get on my computer.

My Acer Predator from 2019: "I'm about to blow this man's mind"

A thin client from Asus circa 09? Uefi, no problem. A 3k Acer gaming laptop from 19? We can't fit something so cutting-edge into the budget!

Your machine has an EFI.

If your machine shipped with windows 8 or above (starting in like 2012) it came with an EFI. You can use the legacy compatibility mode still in all motherboards. Finally starting some time soon they might be dropping legacy bios compatibility mode. But if your machine can boot from an NVME SSD it's got an EFI.
