I am going to be upgrading our 2620 router with a new BOOTROM and 32mb of flash. I am doing this so that I can install a new card. My question is does anyone know if the new memory will have an IOS pre installed. If not I am a little rusty on my cisco commands and if the router doesn't have an IOS to boot to how will I get it on there? Hope this makes sense.

jbenge,
The new FLASH may or may not have an IOS on it - I have seen both but it should say or you can ask who you are buying from.
You should backup your IOS (even if not changing FLASH), I do this on mine to a TFTP server(I use my management station with the TFTP software running - I only run the server software when backing up my config files and IOS)
To backup IOS do a "show flash" to get the name of the IOS image(you will be asked) then do a "copy flash tftp", it will ask you the file name, address of the TFTP and name you want to use on the TFTP.
You should also backup your config file just for good measure - "copy start tftp"
Once you put the new flash in - if you have no IOS in FLASH then the IOS in the boot rom will give you enough to change a few variables and run the command "tftpdnld".
The whole process looks like the following:
rommon 1 >IP_ADDRESS=10.10.10.1
rommon 2 >IP_SUBNET_MASK=255.255.255.0
rommon 3 >TFTP_SERVER=10.10.10.2
rommon 4 >DEFAULT_GATEWAY=10.10.10.1
rommon 5 >TFTP_FILE=c2600-j-l.112-20.P.bin
rommon 6 >tftpdnld
I hope this helps!!

Thanks. One thing that I don't quite get is what are these ip addresses of(below)? Are they the router or tftp server? Or do I have to put the IOS on a computer and access it through a com1 or com2 port? Also do I have to give a file path on the router to find the new IOS? I know what my tftp server ip address is. Sorry to bother.
rommon 1 >IP_ADDRESS=10.10.10.1
rommon 2 >IP_SUBNET_MASK=255.255.255.0
rommon 4 >DEFAULT_GATEWAY=10.10.10.1
rommon 1 >IP_ADDRESS=10.10.10.1
rommon 2 >IP_SUBNET_MASK=255.255.255.0
rommon 4 >DEFAULT_GATEWAY=10.10.10.1
Either COM1 or COM2 will work, makes no difference. The rommon 1 >IP_ADDRESS=10.10.10.1 ip address is the IP address that you would give the router, so that it can access your tftp server, which is specified in this line: rommon 3>TFTP_SERVER=10.10.10.2
The IP addresses used can be different than 10.10.10.x, they're here just as an example.
You'll have to download the IOS onto your PC, then run the tftp service, and point the service to the directory where you stored the IOS file.
