Machine is freezing when attempting to install RedHat on Dell XPS-600.

I've tried Fedora project 4 disk iso downloads and machine hangs at point where it runs /sbin/loader

Also downloaded RedHat 9 (shrike) 3 disk iso and it gets to the point where it asks for wether to check media or skip and will not proceed past this point.

Does anyone know of any problems with this hardware or any BIOS settings I should use to get this to work.

Thanks
