I just got a 2600 router and it shoots this out on boot up:

rommon 2 > meminfo

Main memory size: 64 MB.
Available main memory starts at 0x10000, size 65472KB
IO (packet) memory size: 0 percent of main memory.
NVRAM size: 32KB


This means that my router needs an IOS right? (xmodem or file transfer)

Hi there mate

Will definitely recommend xmodem transfer, because looks like you can access the rommon mode, can't remember if you could do a TFTP from that level.

Also, try opening up the router, and cleaning the contacts for your flash drive, unless it is external, and also the memory modules of the router.

Yes it seams that you need an IOS. You can use TFTP in ROMMON mode using the tftpdnld command. Here is a guide for it:

\http://www.cisco.com/en/US/products/hw/routers/ps259/products_tech_note09186a008015bf9e.shtml

And I think it will also format the flash automatically before copying the IOS. Note: Xmodem is slower, but will do too.

The tftpdnld command worked but now when I power it off I have to tftpdnld all over again. I did copy running-config startup-config but I'm pretty sure that doesn't copy the IOS into flash. Is there a way to do this and confirm that the IOS is loaded into flash before I reload/power cycle?

hmm, not sure, the configuration register value 0x2102 is fine. But the startup-config might be having a boot command that is changing the boot search order. I'd try deleting the startup-config, like this:

delete nvram:startup-config

Note that this command doesn't work in ROMMON mode. So you have to get into the IOS again.
