What does the BIOS do after start up?

Hi,

I know that when the computer starts, the BIOS does a lot: checking peripheral devices, checking for a bootable medium, pulling the bootloader into RAM, etc.

But, after the OS is pulled into RAM and is running, what functions does the BIOS perform?

Does it somehow manage I/O?

Thanks.
 
AFAIK the BIOS handles OS queries about installed hardware (memory, drives, peripheral cards, etc), but not much else. I don't have a link handy, but there's a very detailed blog series that walks through the entire linux boot process, I would imagine it covers this.
 
It loads the bootloader into memory and hands over control to it. The bootloader is then responsible for booting up the OS.
