Hi,

Have a look at this link:-

Look at the section OPERATIONAL COMPARISON

Cisco IOS and Hybrid OS Boot Process

The boot process in both the Cisco IOS and the hybrid operating system models is automatic and transparent to the

user. In the hybrid model, the boot processes are separate for both the switch and the route processors as they each

boot independent operating systems.

In Cisco IOS Software, the two processors (the SP and RP) each load the Cisco IOS Software. Two processors

working together yield two ROMMONs and two bootflash devices. First, the SP boots to ROMMON and loads its

portion of the Cisco IOS Software. When the SP is booted, the software control is passed to the RP so that the second

processor can successfully boot. From a console perspective, the RJ-45 console port on the Supervisor Engine initially

shows information from the SP. During the boot cycle for the Cisco Catalyst 6500 with the Cisco IOS Software,

control is passed to RP CPU as shown in the following statement on the console:
