    The machine freeze up, nor the keybor nor the mouse works. And it's the same
    wether running X or not.

    This is my /etc/modules.conf
    alias scsi_hostadapter aic7xxx
    alias parport_lowlevel parport_pc
    alias usb-controller usb-uhci
    alias eth0 3c509

    It's on an add-on card, concretely a PCI. It's a OX12PCI840 from Oxford

    Bus 0, device 18, function 0:
       Parallel controller: PCI device 1415:8403 (Oxford Semiconductor Ltd) (rev
          IRQ 11.

    Yes I have. I've got Windows 98, and I can use it under Windows 98 with no
