Before starting this process, make sure you have a TFTP server program (TFTPD32 is a good one). Also make sure you have the IOS bin file you want to load onto the router.
Get Server Ready
- Make sure your TFTP server is installed and running.
- Give the server the IP address 10.0.0.254.
- Point the server to the directory holding the IOS file you want to load onto the router.
Download IOS onto router
- Get connected to the router using Hyperterminal.
- Turn on the router and hit CTRL-break on the keyboard as the router is loading to get into ROMmon mode.
- Type the following commands into the router:
- IP_ADDRESS=10.0.0.1
- IP_SUBNET_MASK=255.255.255.0
- DEFAULT_GATEWAY=10.0.0.254
- TFTP_SERVER=10.0.0.254
- TFTP_FILE=c1841-advipservicesk9-mz.124-25b.bin
- tftpdnld
When it asks if you want to continue type yes.
You can also use this script instead:
IP_ADDRESS=10.0.0.1 IP_SUBNET_MASK=255.255.255.0 DEFAULT_GATEWAY=10.0.0.254 TFTP_SERVER=10.0.0.254 TFTP_FILE=c1841-advipservicesk9-mz.124-25b.bin tftpdnld y
Just hit enter after the script copies onto the router.
- type 'reset after the file is done downloading and the router will reset.
