http://www.lpi.org/eng/certification/the_lpic_program/lpic_1/exam_101_detailed_objectives
Topic 101: System Architecture[edit]
101.1 Determine and configure hardware settings[edit]
configure fundamental system hardware.
- Enable and disable integrated peripherals.
- Configure systems with or without external peripherals such as keyboards.
? no keyboard, got no clue how to do a base install without :-)
- Differentiate between the various types of mass storage devices.
sata, ide, scsi ? usb-mass storage ?
- Set the correct hardware ID for different devices, especially the boot device.
- Know the differences between coldplug and hotplug devices.
devices connected to a running system on-the-fly are said to be hotplugged, where those connected prior to system boot are said to be coldplugged. Earlier the kernel used to notify userspace about hotplug events by invoking a helper program registered via the /proc filesystem, but when current systems detect hotplug, they dispatch uevents to userspace via netlink sockets. (netlink sockets are an efficient way to communicate between kernelspace and userspace over the socket API) In userspace the udevd daemon, managing device node creation and removal, receives the uevents and manages hotplug
- Determine hardware resources for devices.
