A bootable device can be storage devices like floppy disk, CD-ROM, USB flash drive, a partition on a hard disk (where a hard disk stores multiple OS, e.g Windows and Fedora), a storage device on local network, etc. [7] A hard disk to boot Linux stores the Master Boot Record (MBR), which contains the first-stage/primary bootloader in order to be ...
Several commands are available by typing them at the prompt, and a list of possible commands is available by entering the command help or man at the prompt. Various system variables for establishing automatic boot settings, parameter strings to be passed to an operating system and the like may also be set from the SRM prompt.
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 ...
The Yellowdog Updater Modified (YUM) is a free and open-source command-line package-management utility for computers running the Linux operating system using the RPM Package Manager. [4] Though YUM has a command-line interface, several other tools provide graphical user interfaces to YUM functionality.
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 stored on the JumpStart server, usually but not exclusively using Network File System .
Some virtual machine infrastructure can directly import and export a boot image for direct installation to "bare metal", i.e. a disk. This is the standard technique for OEMs to install identical copies of an operating system on many identical machines: The boot image is created as a virtual machine and then exported, or created on one disk and then copied via a boot image control ...
GNU GRUB (short for GNU GRand Unified Bootloader, commonly referred to as GRUB) is a boot loader package from the GNU Project.GRUB is the reference implementation of the Free Software Foundation's Multiboot Specification, which provides a user the choice to boot one of multiple operating systems installed on a computer or select a specific kernel configuration available on a particular ...
Traditionally, UNIX platforms called the kernel image /unix. With the development of virtual memory , kernels that supported this feature were given the vm - prefix to differentiate them. The name vmlinux is a mutation of vmunix , while in vmlinuz the letter z at the end denotes that it is compressed (for example gzipped ).
