Memory problems

From a question on groupstudy; the following output was posted of a Cisco 2600 that did not boot up even after the Flash was upgraded to 32MB??????

System Bootstrap, Version 12.1(3r)T2, RELEASE SOFTWARE (fc1)
 Copyright (c) 2000 by cisco Systems, Inc.
 C2600 platform with 65536 Kbytes of main memory

 program load complete, entry point: 0x80008000, size: 0x1c8a8e4

 Error : memory requirements exceed available memory

 *** System received a Software forced crash ***

What could the problem be?

The error tells what the problem is. Convert the 0x04746F90 to decimal to get 74739600 = 74.73MB

According to the error, the image (c2600-adventerprisek9-mz.124-23.bin) being loaded, requires at least 74.73MB of DRAM. The flash memory which was upgraded was not the issue, since that only holds the IOS image.

My suggestion? Always goto Cisco Feature Navigator or short URL http://www.cisco.com/go/fn to see the DRAM/Flash memory requirements before just downloading the IOS image.

As per the FN page the recommended required memory for this image c2600-adventerprisek9-mz.124-23.bin is (DRAM/Min Flash : 128/32)
