Rooting Process Update??

[Natureboyhcg]

i have searched around and cant find an answer to this but is there a rooting process for ICS on a tablet rooted from kies.
the main difference between the process everyone is saying to do is once you enter into recovery mode the option to update through sd card no longer exist therefore you cant find the update.zip

the options are to update from recovery cache or update from external storage.. any ideas?
