Before upgrading the router memory, I had this in place:
C2600 platform with 65536 Kbytes of main memory
16384K bytes of processor board System flash (Read/Write)
I bought 64 MB extra main memory and 16 MB extra flash memory. When I opened up the router, the insides looked like this diagram:
I had a single 64 MB DRAM DIMM in the "Primary memory" slot with one free. I had no memory in the "System-code SIMM (Flash memory)" slot, since the 2651XM must ship with 16 MB on the motherboard. Once I snapped in the extra memory, my router recognized it without any trouble, as will be seen later.
I also decided to upgrade from a 12.2 release to 12.3. My old IOS was 12.2(11)T10, which corresponded to the c2600-ik9s-mz.122-11.T10.bin image. The 'show flash' command showed this after the memory upgrades:
gill#sh flash
System flash directory:
File Length Name/status
1 14962584 c2600-ik9s-mz.122-11.T10.bin
[14962648 bytes used, 18591784 available, 33554432 total]
32768K bytes of processor board System flash (Read/Write)
First I searched for a suitable IOS from the Cisco IOS Feature Navigator and Upgrade Planner tools. I located a version of IOS which offered NetFlow and SSH v2 in the 12.3 train, 12.3(4)T4 (image c2600-a3jk9s-mz.123-4.T4.bin). I downloaded it to a TFTP server on the same network as the router, into the TFTP server's /tftpboot directory.
I did not make a copy of the existing router flash image as I already had it elsewhere for safekeeping.
Next I copied my startup-config to the TFTP server:
gill#copy startup-config tftp://172.27.20.5/gill-startup-config
Address or name of remote host [172.27.20.5]?
Destination filename [gill-startup-config]?
!!
2200 bytes copied in 0.072 secs (30556 bytes/sec)
Now I was ready to copy my new flash image to the router:
gill#copy tftp flash
Address or name of remote host []? 172.27.20.5
Source filename []? c2600-a3jk9s-mz.123-4.T4.bin
Destination filename [c2600-a3jk9s-mz.123-4.T4.bin]?
Accessing tftp://172.27.20.5/c2600-a3jk9s-mz.123-4.T4.bin...
Erase flash: before copying? [confirm]
Erasing the flash filesystem will remove all files! Continue? [confirm]

[OK - 24299960 bytes]
Verifying checksum... OK (0x5193)
24299960 bytes copied in 182.832 secs (132909 bytes/sec)
Next I checked to see if it was loaded:
gill#sh flash
System flash directory:
File Length Name/status
1 24299960 c2600-a3jk9s-mz.123-4.T4.bin
[24300024 bytes used, 8730120 available, 33030144 total]
32768K bytes of processor board System flash (Read/Write)
This looked fine, so I changed the system boot parameters to use the new image, copied the running-config to startup-config, and reloaded the router:
gill#conf term
Enter configuration commands, one per line. End with CNTL/Z.
gill(config)#no boot system flash c2600-ik9s-mz.122-11.T10.bin
gill(config)#boot system flash c2600-a3jk9s-mz.123-4.T4.bin
gill(config)#exit
gill#

Destination filename [startup-config]?
Building configuration...
[OK]
gill#reload
Proceed with reload? [confirm]
01:22:32: %SYS-5-RELOAD: Reload requested by console.
I then watched the router come up:

Everything looks fine, including the time setting via NTP. I also looked again at the flash and then the filesystem:
