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?

They're an embedded device, plain and simple. Among other things, this means that there's not a layer that handes off the hardware in a ready state to the OS, and not even an ACPI to tell them what and where the hardware is, the OS needs to already know via a device tree.
