ieXbeta Board

Does anyone have an image of a diagnostic cd or tech tool, or even an old os 10 x cd? I need to boot rom cd to find out if something is bad. My mac takes forever to boot and hangs right after 75% of the time.

This happend before a little then a lot after I added new cmos battry to solve data and time.

I have windows keyboard to so how do I reset the pram?
