Hi Trevor,
When you post, you will get more helpful responses if you state
SPECIFICALLY what problem you are having. It is also best to copy and
paste your console session into your post. A post like "I've got a
problem with X" is annoying and it means that the rest of us have to
play "20 Questions" to even find out what the problem is and most won't
bother.
That said, let me correct some of the misinformation on this thread. I
do not believe it is possible to load IOS or anything else via XMODEM or
ZMODEM on a 2500 series router. XMODEM functionality is on a few routers
(2600, 3600, etc.) but it is not available on the 2500 series.
Two of the most common problems encountered in upgrading flash on a 2500
series router are as follows:
1. Some of the newer flash memory SIMMS simply will not work with the
older Boot ROMs in the 2500 series router. Call Cisco Customer Service
800 553-6387, Option 3 to order replacement Boot ROMs. They are free,
you just pay for shipping. The part number is BOOT-2500=.
2. If the router recognizes your new flash you may just need to erase
and repartition the flash.
When you boot the router you will end up in Boot ROM mode (this is
equivalent to config register setting 0x2101) and your prompt will look
like:
Router(boot)>
This means you are running from a minimal version of IOS out of the Boot
ROM, but the router will still recognize your config file and you can
still enter commands.
This is what you can do to remove the partitioning:
Router(boot)>en
Password:
Router(boot)#conf t
Enter configuration commands, one per line. End with CNTL/Z.
RouterA-2511(boot)(config)#no partition flash
RouterA-2511(boot)(config)#end
Router(boot)#wr mem
Here's what "show flash all" looks like with an IOS loaded:
Router(boot)#show flash all

Hi,
I purchased a 2509 access router and it cam w/ 4Mb of flash. I am want to upgrade it to 16Mb so I purchased (2) 8Mb flash. My question is how do I load the ios on the (2) blank flash chips? I am having a problem doing this. Your help is appreciated. Thanks.
