OS on CF Graphing on hard drive

Can I use a CF to store the MT operating system and utilizing a hard drive to store/capture graphing? If so where do I set this up?

I touched on this recently with MikroTik and I do not believe it is possible right now.

It would be a nice feature for MikroTik to add on an upcoming version!

Best,

Brad

why do you need that? Graphing takes just a few kilobytes of space.
