/***************************************************************************
PC_DEVICE - User supplied Device driver. 

        This now contains the PC_BDEVSW table. Routines in RTFS which
        need IO call the device drivers directly through the pc_bdevsw
        table. This model is much cleaner and eliminates a lot of layering.

        When you have your device drivers written plug them into this table.
        
        Call EBS if you haven't written your drivers yet. We may have one 
        available.
