If you are just doing PIO with generic IDE interfacing then its simply a matter of telling Linux that there is an interface at these addresses with these port operations and it'll just do the rest for you, except hotplug. Basically for the standard port layouts. hw_regs_t hw; ide_hwif_t *hwif; memset(&hw, 0, sizeof(hw)); ide_std_init_ports(&hw, base_port_num, ctrl_port); hw.irq = IRQ_LINE; hw.dma = NO_DMA; index = ide_register_hw(&hw, &hwif); If the port layout is non standard and you use mmio etc then you need to set hw up by hand. drivers/ide/legacy/macide.c is a good example of interfacing a non standard controller.
