Q
what is the boot order?
A
- power-on self-test (POST) program stored in ROM
- Next, the switch loads the boot loader software. The boot loader is a small program stored in ROM and is run immediately after POST successfully completes.
- The boot loader performs low-level CPU initialisation. It initializes the CPU registers, which control where physical memory is mapped, the quantity of memory, and its speed.
- The boot loader initializes the flash file system on the system board.
- Finally, the boot loader locates and loads a default IOS operating system software image into memory and hands control of the switch over to the IOS.
