I think if you reverse the slots they're in, it'll actually show 12 megs, and be useable that way. I'm not positive though...

You are right. When I inserted the memory individually, the router displayed one was 4m and another one was 8m. That explained why I can not load the bigger size IOS.
Thanks a lot.

Could be bad flash, or a mismatch. I seem to remember something about the 2500s where a combination of a 8 meg and a 4 meg module would show 16 megs, but would never accept an image over 12 megs. Try putting the modules in one at a time, and make sure they're both 8 megs and functioning.

Subject: cisco 2500 router upgrade problem.
I am upgrading the IOS (12.2 code) on a cisco 2503. I got the "invalid checksum" every time when I finished the download.
The router has 16M flash as displayed below:
r2-2503(boot)#sh flash
System flash directory:
File Length Name/status
1 16505800 c2500-jk8os-l.122-1d.bin [invalid checksum]
[16505864 bytes used, 271352 available, 16777216 total]
16384K bytes of processor board System flash (Read/Write)
I have used different TFTP servers for the upgrade. If I only upgraded the IOS which was less than 8 M, there was no problem.
I can not upgrade the code bigger than 8M at all, even some of the IOS are 14M or 13M. Can someone help?
Thanks.
