Boot Sequence
All Cisco products do not have the same components or mechanisms to boot. This section describes the boot
sequence in the Cisco 1600 Series Router.
The boot ROM which is read−only memory contains two programs:
The ROM monitor or ROMmonThe ROMmon is a diagnostic image that provides the user with a
limited subset of commands. This diagnostic mode is most often used during recovery procedures
(forgotten password or wrong/corrupted Cisco IOS software). It is possible to view or modify the
configuration register from this mode and to perform a Cisco IOS software upgrade through the
xmodem transfer.
•
The Bootstrap (RxBoot)The bootstrap program is written to find and load a copy of Cisco IOS
software based on the settings of the configuration register. The Cisco IOS software image can be
located either on the system Flash, on a PCMCIA Flash card, or on a Trivial File Transfer Protocol
(TFTP) server. Usually, the Cisco IOS software image resides on the PCMCIA Flash card.
•
When a Cisco 1600 Series Router is first powered up, the boot−up sequence involves these steps:
ROMmon (in Boot ROM) takes control of the Main Processor and handles the following:
Control register settings.♦
Console settings.♦
Initial diagnostic tests of memory and other hardware.♦
Data structure initialization.♦
Flash file system (MONLIB) setup.♦
