that help dealing hardware,system time settings,etc. But how to diplay a
"hello" using BIOS?

Please answer my doubt..also.
Suppose your PC do not have any OS installed.(It has bootstrap loader).
Then,
1. What will happen as an when you turn ON the system? Will it display
anything?
2. How to print a hello on monitor without any OS?
3. How to use computer or operate anything without any OS? If no OS is
there, then what does it use for user interface?
What is the case for above questions when there is no bootstrap loader
These sound like test questions.
If you have done your microprocessor studies properly, you can figure
out what a CPU does on reset/power on.
Have you heard of BIOS?
