837 IOS Upgrade

I am new to Cisco routers. I just bought a used 837, managed to configure
it and it is working fine.
Its IOS is an older version and wont work with the latest SDM. Is there a
version of SDM which will work with my 837's IOS version?

Or maybe I should upgrade the IOS but later IOS versions I have seen require
larger memory than my 837. Does anyone know of an IOS which will work with
SDM and which will work with the memory level of my 837?

Thank you


Currently my 837 has:

IOS (tm) C837 Software (C837-K9O3Y6-M), Version 12.2(YN, EARLY DEPLOYMENT
RELEASE SOFTWARE (fc1)
Synched to technology version 12.2(11.2u)T

CISCO C837 (MPC857DSL) processor (revision 0x400) with 29492K/3276K bytes of
memory.
Processor board ID AMB07170HFG (3265805387), with hardware revision 0000
CPU rev number 7
Bridging software.
1 Ethernet/IEEE 802.3 interface(s)
1 ATM network interface(s)
128K bytes of non-volatile configuration memory.
8192K bytes of processor board System flash (Read/Write)
2048K bytes of processor board Web flash (Read/Write)

first of all you will need to access the router through a console cable, and connect the router with an ethernet cable to the pc, and setup a tftp server at your pc with the ios you would like to put on.
then simply write copy tftp flash
it will ask you for the ip address of the tftp server and then the file name.
or you can see at:
netadmintools.com/art98.html

if in doubt ask me again.

I have run 837s with less then the recommended memory

memory-size iomem

was the key.

*HOWEVER* note that you might easily end up
with a router that won't boot which will require recovery
with xmodem and confreg fidddling.

Of course I was not using SDM and the extra memory might
be needed for it

check your memory usage with sh mem

router#sh mem
Head Total(b) Used(b) Free(b) Lowest(b)
Largest(b)
Processor 83099124 70676188 29800736 40875452
38709808 36842076
I/O 7400000 12582912 3948464 8634448
8513040 8517372

paying particular attention to I/O and see if you can
change the iomem percent and still have a workign router.

If I could find a copy of SDM Express I'd try that.
Maybe it doesn't require as much memory as the full SDM

I've searched but cant find it.

Thank you binary_dreamer but I know how to do the upgrade. I need to know what version IOS I can upgrade to having regard to the amount of memory my 837 has.
