hi,

what features do you need for your 1841?

you can buy either a 64 MB or 128 MB CF card which are cheap nowadays.

you could check the features on Cisco's software download site or you can browse at cisco.com/go/fn.

hi,

the IOS adventerprisek9 12.4 and above requires 64 MB flash.

i saw this one available on cisco's download website and only requires 32 MB flash:

c1841-adventerprisek9-mz.123-11.YZ2.bin

1841-adventerprisek9-mz.124-25g.bin is listed as requiring 64 MB of flash - however, the file is only 24.35 MB in size, so if the remaining space is enough for other requirements (crash files, archived configs, etc) then it should work...

[ghostinthenet]

Is there a feature that you require in the Advanced Enterprise image that isn't present in the Advanced IP Services image? The Advanced IP Services 12.4.25g image only requires 32Mb of flash and should work well unless there's something specific that it can't do.
