Hi there,

Yes you can run DOS in either XP, Vista or W7 but it will not show in full screem instead it will show as a small box.

I know several folks still using W98, parts are available to continue using it BUT don't try going online ever

Lets checkout the hardware and proceed, you'll have to disconnect from power then open the case and with much light look for the FCC label so we can find the right part.
