What is BIOS? |
BIOS is known as firmware - software that's hard-coded into hardware but that can be modified. |
|
|
What steps occur during a POST (Power On Self Test)? |
1. the bios is initialized and checked 2. The CPU registers are verified 3. the size of main memory, or RAM, is verified and, optionally, RAM integrity is checked 4. system devices are detected and initialized 5. the boot device with the highest priority is selected and its MBR (Master Boot Record) is executed. |
