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?

A BIOS does not inherently have to have a configuration utility.

This right here.

My first PC (a 386 circa 1989) did not have a built-in config utility. It had a bootable floppy disk that could configure the BIOS settings. I think all it could change was the system time and the CHS values of the hard drive(s).

Kinda funny how we’ve somewhat returned to that. Modern EFIs typically let you change settings from within your OS. I remember having a motherboard in like 2011 or 2012 with a great GUI that let me tweak everything. I’d set an overclock in the OS and just reboot for it to take effect.

Not sure why more boards don’t offer this anymore other than maybe security. But like with cryptic ass programs I can still change bios settings.
