If so, could this perhaps be done by bringing the Hinds > PnP BIOS driver into the kernel and interfacing isa-pnp to it? - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
