How to save to internal ram????

I dont know how to save to the ram and not the CF card, cause i have some kits and samples and some other stuff on there but it isnt that much and its saying its full, and when i pop out the card it wont save at all, like the do it button wont flash.

Ideas???

You cannot do this . Ram is volitile memory ..volitile meaning it loses the information stored within it when powered off. Flash memory .. I.E. Flash Cards are what is known as non-volitile memory and retains data without power..... Now the 500 may have a small amount of internal flash memory like the 1000 but I am not sure as I do not have one . If so you are limited to that space which would be small...
