SystemRescue (Previously known as "SystemRescueCD") [4] is a Linux distribution for x86-64 and IA-32 computers. [5] The primary purpose of SystemRescue is to repair unbootable or otherwise damaged computer systems after a system crash. SystemRescue is not intended to be used as a permanent operating system.
Memtest86+ is included, optionally or by default, in many Linux distributions, including Debian, [18] the derived Ubuntu, and Arch Linux. [19] Ubuntu includes it as part of the default installation if the machine is booting in BIOS mode, showing it in the GRUB OS-select menu; [20] the version 6.0, UEFI-capable, is available from Ubuntu 23.04 ...

This is because CMOS may experience a failure mode known as a stuck-open fault, which cannot be reliably detected with one test vector and requires that two vectors be applied sequentially. The model also fails to detect bridging faults between adjacent signal lines, occurring in pins that drive bus connections and array structures.
coreboot, formerly known as LinuxBIOS, [5] is a software project aimed at replacing proprietary firmware (BIOS or UEFI) found in most computers with a lightweight firmware designed to perform only the minimum number of tasks necessary to load and run a modern 32-bit or 64-bit operating system.
It also contains a command-line interface, which makes it easier to fix or modify GRUB if it is misconfigured or corrupt. [16] Loadlin is a bootloader that can replace a running DOS or Windows 9x kernel with the Linux kernel at run time. This can be useful in the case of hardware that needs to be switched on via software and for which such ...
During the POST, the BIOS must integrate multiple competing, changing, and even mutually exclusive standards and initiatives for the matrix of hardware and operating systems the PC is expected to support, although at most only simple memory tests and the setup screen are displayed. The principal duties of the main BIOS during POST include:
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
