HAL (Hardware Abstraction Layer or rather Hardware Annotation Library) is a software subsystem for UNIX-like operating systems providing hardware abstraction. HAL is now deprecated on most Linux distributions and on FreeBSD. Functionality is being merged into udev on Linux as of 2008–2010 and devd on FreeBSD.
A hardware abstraction layer (HAL) is an abstraction layer, implemented in software, between the physical hardware of a computer and the software that runs on that computer. . Its function is to hide differences in hardware from most of the operating system kernel, so that most of the kernel-mode code does not need to be changed to run on systems with different hardwa
DeviceKit is a modular hardware abstraction layer designed for use in Linux systems that is designed to simplify device management and replace the current monolithic Linux HAL. DeviceKit includes the ability to enumerate system devices and send notifications when hardware is added or removed from the computer system.
Adeos (Adaptive Domain Environment for Operating Systems) is a nanokernel hardware abstraction layer , or hypervisor, that operates between computer hardware and the operating system (OS) that runs on it. [1] [2] It is distinct from other nanokernels in that it is not only a low level layer for an outer kernel.
The Windows installation procedure determines which ones are appropriate for the current platform and copies it to the hard drive, renaming it to hal.dll if necessary. Among the criteria for this selection are: the presence of an ACPI -compatible BIOS, the presence of an APIC , and whether or not multiple processors are present and enabled.
In addition to the OS APIs, the OS abstraction layer project may also provide a hardware abstraction layer, designed to provide a portable interface to hardware devices such as memory, I/O ports, and non-volatile memory.

udev (userspace /dev) is a device manager for the Linux kernel.As the successor of devfsd and hotplug, udev primarily manages device nodes in the /dev directory. At the same time, udev also handles all user space events raised when hardware devices are added into the system or removed from it, including firmware loading as required by certain devices.
