As we all know that BIOS is the thing that is started when we power on the computer and it then gives instructions to all the devices to do some particular thing. But in the same way when the power is given to a particular hardware device say RAM then it may perform some self test or something to be ready for instructions from BIOS. e.g. After power on: - The RAM may initiate some of its registers. - May increment any counter. - May get itself ready for input. and other hardware components may do this as well ... I want to get this information. The phenomenal change of hardware components when the get powered on!!

e.g.

After power on:

- The RAM may initiate some of its registers.
- May increment any counter.
- May get itself ready for input.

and other hardware components may do this as well …
