Cisco Cisco IPS 4255 Sensor

The BIOS/ROMMON upgrade utility (IDS-4215-bios-5.1.7-rom-1.4.bin) upgrades the BIOS of the 
IDS 4215 to version 5.1.7 and the ROMMON to version 1.4. 

To upgrade the BIOS and ROMMON on the IDS 4215, follow these steps:

Download the BIOS ROMMON upgrade utility (IDS-4215-bios-5.1.7-rom-1.4.bin) to the TFTP root 
directory of a TFTP server that is accessible from the IDS 4215. 

Make sure you can access the TFTP server location from the network connected to the Ethernet 
port of the IDS 4215.

Boot the IDS 4215. While rebooting, the IDS 4215 runs the BIOS POST. After the completion of POST, 
the console displays the message: 

Evaluating Run Options ...

for about 5 seconds. 

Press Ctrl-R while this message is displayed to display the ROMMON menu. 

The console display resembles the following:
