Re: Is loading IOS into 2500 with no Flash possible? [7:14375]
Yes, it can be done. 2500 can be made to run from RAM. Use a boot System command .

Re: Is loading IOS into 2500 with no Flash possible? [7:14375]
I believe the 2500 series runs at least partly from flash (as opposed to routers that move their entire IOS from flash into RAM and run it from RAM), so you should NOT be able to run a 2500 series router without any flash.

RE: Is loading IOS into 2500 with no Flash possible? [7:14375]
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.

[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! John >>> "Patrick Ramsey" 7/31/01 11:28:50 AM >>> So how do you put the ios on them?
