514 | initially work for you. It may help to enable device hotplugging | ||
515 | support. As of this writing the exact hardware interface is | ||
516 | strongly in flux, so no good recommendation can be made. | ||

543 | singleprocessor machines. On a singleprocessor machine, the kernel | ||
544 | will run faster if you say N here. | ||
