The standard way to load new software on your router is using the copy tftp flash
privileged EXEC command from the Cisco IOS software command-line interface
(CLI). However, if the router is unable to boot the Cisco IOS software, you can
load new software while in ROM monitor mode.
This section describes how to, while in ROM monitor mode, load a Cisco IOS
software image from a remote TFTP server to the router Flash memory. Use the
tftpdnld command only for disaster recovery because it erases all existing data in
Flash memory before downloading a new software image to the router.
The 10BASE-T Ethernet Port is not active in ROM monitor mode, and thus
cannot be used for TFTP Download.
This section describes the system variables that can be set in ROM monitor mode
and that are used during the TFTP download process. There are required and
optional variables.
The commands described in this section are case-sensitive and must be entered
exactly as shown in the lists.
