I'm unsure about this one but this is another one of the burning questions I have on the top of my head. Does Android have a BIOS? If not, how does it boot up? What is the software that actually boots it up and can you replace it?

This question came from our site for computer enthusiasts and power users.

  • It is probably called firmware. That would be used to start the machine. My Apple iPhone has firmware and it was updated at the last IOS 13.1 Update. I expect your Android would do something similar. – John Sep 28 at 20:31

    No. Android is software, an operating system. BIOS is also software (or firmware) that is part of the computer hardware. BIOS is IBM PC terminology that traces back to PC-DOS's roots to CP/M. Other types of computers and processors (e.g. ARM) do not use that terminology for their integrated firmware. – sawdust Sep 29 at 0:10

Android is an Operating System, similar to Windows. Windows does not have a BIOS either, the computer has a BIOS.

Phones don't have a BIOS though, they have firmware.

    Phones don't have BIOS. Vendors implement boot process inside their closed source SoCs. PCs have ACPI, phones have Device Trees (mostly). Bootloaders are also different, again closed source on phones. Only Linux kernel is same, that too modified. Userspace is again entirely different. On Android there is no console login, no traditional X server. – Irfan Latif Sep 29 at 2:15
