Hi guys,
What are the exact functions of the BIOS.
As I understaood, first of all, BIOS is responsible of booting the PC because the memory is empty.
Second, all hardware (video, ports, sound..) need an accompanying program that provides the CPU with the code necessary to comminucate.. this code is in the System BIOS.
(I am a bit confused here.. someone told me that this code can be found in an independant BIOS for every hardware (video), another one told me that this code can be found in the driver that come with the hardare) !!
I have 2 questions here:
1) These are the 2 main functions of the System BIOS. right??
2) But where do we find these "codes" that are needed for a communication between hardware and CPU? System BIOS?independant BIOS? or software drivers ? (or everyone is an option?)
thanks !!
