HELP!!! Chipboard nightmare

[annabella]

Hi everyone. I am tiling my bathroom floor. I have pulled up the lino to reveal a rather hideously tiled floor. It would seem that whoever laided the floor did so with what appears to be a cement based adhesive straight on to the chipboard. Having removed the tiles I am left with a totally uneven floor covered in what I can only describe as the toughest cementy material known to man. I have tried chiselling it and it is not making a dent. Any advice?
