GRUB 2, elilo and systemd-boot serve as conventional, full-fledged standalone UEFI boot managers (a.k.a. bootloader managers) for Linux. Once loaded by a UEFI firmware, they can access and boot kernel images from all devices, partitions and file systems they support, without being limited to the EFI system partition.
Many Linux distributions ship a single, generic Linux kernel image – one that the distribution's developers create specifically to boot on a wide variety of hardware. . The device drivers for this generic kernel image are included as loadable kernel modules because statically compiling many drivers into one kernel causes the kernel image to be much larger, perhaps too large to boot on ...
cfdisk is a Linux partition editor, similar to fdisk, but with a different, curses-based user interface. It is part of the util-linux package of Linux utility programs. The current cfdisk implementation utilizes the libfdisk library [ 1 ] and supports partitioning of disks that use Master boot record , GUID Partition Table , BSD disklabel , SGI ...
The partition type (or partition ID) in a partition's entry in the partition table inside a master boot record (MBR) is a byte value intended to specify the file system the partition contains or to flag special access methods used to access these partitions (e.g. special CHS mappings, LBA access, logical mapped geometries, special driver access, hidden partitions, secured or encrypted file ...
Sometimes, the loop device is erroneously referred to as loopback device, but this term is reserved for a networking device in operating systems. The concept of the loop device is distinct. In BSD-derived systems, such as NetBSD and OpenBSD , the loop device is called "virtual node device" or "vnd", and generally located at /dev/vnd0 , /dev ...
A driver communicates with the device through the computer bus or communications subsystem to which the hardware connects. When a calling program invokes a routine in the driver, the driver issues commands to the device (drives it). Once the device sends data back to the driver, the driver may invoke routines in the original calling program.
The device shines a light through the fingertip, seeking out oxygen-rich blood. The more light that’s absorbed, the better, in theory. But that light is also absorbed by melanin, or pigment, in ...
