How to install new dashboard?Old softmod?

Hi, I softmodded my xbox a few months ago and installed linux on it,I guess I used an older softmod as I don't have a replacement dashboard,I was wondering if I have to ftp in to replace the dashboard or can I do it from my xebian installation.Also will the replacement dashboard allow me to run my emulators and where do they have to be?any help would be appreciated.Sorry for the noob question,I spent most of my time on my psp:)
I have googled it but most sites deal with softmodding for the first time and mine is already done,wish I had done it with one that included the dashboard!
How can I ftp in if I don't have a dashboard that allows it?
Oh well,guess I might have to redo it all.

i dont get what you want to doo exactly cause i prob will be able to help
