There are several posts regarding 2500 routers and BIOS/FLASH replacement,
upgrades, in the archives, some of which date back to 1999.
A quick search in the archives for '2500 boot rom' yeilded 8 hits.

Subject: Re: Is loading IOS into 2500 with no Flash possible? [7:14375]
The 2500 have a basic IOS stored on Boot ROMs. If no IOS is present in
flash, then the router will boot to Config Helper mode (or boot helper,
or something like that) and you can use TFTP to transfer an image to
flash. You said your routers have *no* flash. I thought 2500s had some
built-in flash, but if they don't and you really don't have any flash
then you're hosed.
Fortunately, 2500 flash probably isn't too expensive nowdays.
Good luck!

So how do you put the ios on them? (just curious) I've never had to
troubleshoot a 2500. The only 2500 we have ever had, just sits there
and routes no problem...

The 2500 series can not do XMODEM. Also, these are not run-from-RAM
devices; they run from flash. The 2600 series can do what you are
attempting but not the 2500s.

Hi,
I have 3 2500's that have 16meg RAM but no Flash memory. I had read
where
you could boot to ROMMON> and issue an XMODEM command and have the IOS
transfered to the box. There is also a option to load it into RAM and
run it
(-r I think).
Sounded good but when I boot to ROMMON, the xmodem command is not
there. I
have the latest boot ROM from Cisco on these as well. What gives?
Documentation wrong? Am I doing something wrong? Is this even
possible?
Thanks for the help,
Scott
