The first release of DragonFly BSD with NVMe support is version 4.6. [73] FreeBSD Intel sponsored a NVM Express driver for FreeBSD's head and stable/9 branches. [74] [75] The nvd(4) and nvme(4) drivers are included in the GENERIC kernel configuration by default since FreeBSD version 10.2 in 2015. [76] Genode
Ventoy is a free and open-source utility used for creating bootable USB media storage devices with files such as .iso, .wim, .img, .vhd(x), and .efi.Once Ventoy is installed onto a USB drive, there is no need to reformat the disk to update it with new installation files; it is enough to copy the .iso, .wim, .img, .vhd(x), or .efi file(s) to the USB drive and boot from them directly.
The Raspberry Pi Foundation was created as a private company limited by guarantee in 2008, [8] and was registered as a charity in 2009 [9] by people at the University of Cambridge Computer Laboratory who had noticed a decline in the number and skills of young people applying for computer science courses.

Das U-Boot (subtitled "the Universal Boot Loader" and often shortened to U-Boot; see History for more about the name) is an open-source boot loader used in embedded devices to perform various low-level hardware initialization tasks and boot the device's operating system kernel.
Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.
SeaBIOS is an open-source implementation of an x86 BIOS, serving as a freely available firmware for x86 systems. Aiming for compatibility, it supports standard BIOS features and calling interfaces that are implemented by a typical proprietary x86 BIOS.
One of the major improvements the PCI Local Bus had over other I/O architectures was its configuration mechanism. In addition to the normal memory-mapped and I/O port spaces, each device function on the bus has a configuration space, which is 256 bytes long, addressable by knowing the eight-bit PCI bus, five-bit device, and three-bit function numbers for the device (commonly referred to as the ...
