Why can't my 2620 load this image?

[hummer3331973]

Hi-

I've downloaded a new IOS (c2600-i-mz.123-26.bin) to my 2620 via TFTP but I'm getting this error:

 Not enough memory in the system to run this image
 Required pmem/iomem: 26934890/419430
*** System received a Software forced crash ***

That's weird because the new IOS requirement is only DRAM=32/Flash=8. On a "dir flash:" this is what I'm seeing:

rommon 9 > dir flash:
         File size           Checksum   File name
   7754580 bytes (0x765354)   0x1fd9    c2600-i-mz.123-26.bin

I don't have other slots or drives. Here's also "meminfo":

Available main memory starts at 0x10000, size 24512KB
IO (packet) memory size: 0 percent of main memory.
NVRAM size: 32KB

What else I'm missing here? Thanks and this is probably a very easy question for some.

It will probably be helpful if I put here the whole boot-up process:

that image is probably compressed at 7754580 bytes, and when it loads the image it is expanding beyond your 8 meg

I'm sorry I'm still navigating my way on this.

I've checked the Cisco site and DRAM 32/FLASH 8 is the lowest they have for all IOS.

How will I know which image fits my unit? I'm confuse.

That's why. What other image did you have before? Is this for home lab practice? If so, you won't be able to do much with that image. I don't think it even supports 802.1Q...

Hi Burt-

I only need the most basic feature (IP routing, GLBP and HSRP).

I wasn't able to get the previous image. This is an old router and nobody knows the pwd,and I have to do some password recovery to get inside the router.

What do you mean by "Available main memory starts at 0x10000, size 24512KB"?

Thanks.

 

[burtsbees]

That's what you posted. Not sure EXACTLY what it means, but it says only 24MB is available...

You will have to do something very risky we only do when absolutely necessary.

Delete the current image and boot image, squeeze the flash, then tftp the image up. It's a great idea to not reboot the router without an image

Yes---forgot about squeeze flash. Good idea.

He's got enough flash. He doesn't have enough DRAM. These images are compressed. The compressed image fits into 8 MB of flash, but decompresses into DRAM during boot.

Hummer, if you are running 32M DRAM you may want to upgrade to 64M, or find a smaller IOS.
We have a 2621 with 64M DRAM that decompresses 10M IOS's just fine.

I tried and tried to find a 2600 that runs 32M DRAM on our network, but couldn't

There are some 12.0 mainline images that would fit. But those won't have the features you're looking for. You might even be able to find 12.1 images that would work. I can't remember if there are any 12.2 images that would work with less than 32 MB of DRAM.

TOTALLY missed that---I concentrated on the fact that you looked on Cisco's site and found the requirements, and assumed that you had them fulfilled...you only have 24MB DRAM...

Thanks for the info everyone. My initial thought was there were images not erased when I TFTP'd the new IOS, specially when I tweaked with the registers during my pwd recovery.

I'll try sourcing for additional DRAM.
