IBM Surepos 500 Formatted, please help

Hi,

This is my first ever post, am a complete amateur and need help.
I have the EPOS till but unfortunately disk went bad so I just formatted it.
I dont have any software or drivers.
I need to set this up from scratch.
What are the steps I need to take (I can go the Linux and windows root) and where can I obtain some free software for a take away.

Any help would be appreciated as I dont have the budget for an epos engineer however I am computer literate.

Thanksinadvance

H
