Network booting, shortened netboot, is the process of booting a computer from a network rather than a local drive. This method of booting can be used by routers, diskless workstations and centrally managed computers (thin clients) such as public computers at libraries and schools.
A high-level PXE overview. In computing, the Preboot eXecution Environment (PXE; often pronounced as / ˈ p ɪ k s iː / pixie, often called PXE Boot/pixie boot) specification describes a standardized client–server environment that boots a software assembly, retrieved from a network, on PXE-enabled clients.
ONIE enables network switch hardware suppliers, distributors and resellers to manage their operations based on a small number of hardware stock keeping unit (SKUs). This in turn creates economies of scale in manufacturing, distribution, stocking, and return merchandise authorization (RMA) enabling an ecosystem of both network hardware and ...
At boot time, a workstation that has been set to boot from PXE will issue a BOOTP request via the network. Once the request is received, the DHCP Server will supply an IP address to the machine, and the DNS server will point the client computer to the RIS server, which in turn will issue a disc boot image (often called the "OS Chooser").
A JumpStart and network booting server is set up on the same local network as the system(s) to be installed. Technically, the network boot and install servers can be separate functions, but they are typically the same system. Once a client system begins the JumpStart process, it then accesses the operating system component software packages ...
providing for a network installation of Linux distributions like Fedora, Debian, etc., providing machines via PXE boot (or similar means) with a small size operation system (e.g., DSL, Puppy Linux, FreeDOS). Providing a DRBL-Server Installation on a machine running a supported Linux distribution via installation script, Live CD.
As with the second-stage boot loader, network booting begins by using generic network access methods provided by the network interface's boot ROM, which typically contains a Preboot Execution Environment (PXE) image. No drivers are required, but the system functionality is limited until the operating system kernel and drivers are transferred ...
Although its basic role was to implement a PXE stack, iPXE can be also used as a network boot manager with limited capabilities for menu-based interaction with end users. iPXE can fetch boot files using multiple network protocols, such as TFTP, NFS, HTTP or FTP. iPXE can act as a boot loader for the Linux kernel, with support for multiboot.
