The BIOS itself is stored in ROM which does not require any power to maintain its contents. The BIOS setting are stored in a very low power CMOS SRAM with a battery to keep it powered up even when the computer itself is switched off (the BIOS does nothing to maintain this, it is done in the hardware).

Which memory is cleared once the computer is switched off?
RAM memory is cleared when a computer is turned off.
Is BIOS a volatile or nonvolatile memory?
BIOS is a program (stored in ROM), not a memory.However the BIOS uses a battery backed up RAM to store a variety of settings and parameters. This BIOS RAM is itself volatile (it can only store data when powered), however the battery backup provides power to this RAM when the main power of the computer is off (making it act as if it were nonvolatile). When this battery dies the BIOS RAM will lose its data and (after the battery is replaced) the machine may have to be reconfigured from scratch before the machine will startup correctly.
