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 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.
