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 a list of commands from the GNU Core Utilities for Unix environments. These commands can be found on Unix operating systems and most Unix-like operating systems. GNU Core Utilities include basic file, shell and text manipulation utilities. Coreutils includes all of the basic command-line tools that are expected in a POSIX system.
This is a list of POSIX (Portable Operating System Interface) commands as specified by IEEE Std 1003.1-2024, which is part of the Single UNIX Specification (SUS). These commands can be found on Unix operating systems and most Unix-like operating systems.
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.

It is free software released under the terms of the GNU General Public License version 2. It has pciutils and zlib as dependencies, and for some programmers also libftdi and libusb.
At least one Asus board [which?] is known to have faulty BIOSes with corrupt ACPI IVRS tables; for such cases, under Linux, it is possible to specify custom mappings to override the faulty and/or missing BIOS-provided ones through the use of the ivrs_ioapic and ivrs_hpet kernel parameters.
e820 is shorthand for the facility by which the BIOS of an x86-based computer system reports the memory map to the operating system or boot loader. [1] It is accessed via the int 15h call, by setting the AX register to value E820 in hexadecimal. It reports which memory address ranges are usable and which are reserved for use by the BIOS. [2]
Ralf Brown's Interrupt List (aka RBIL, x86 Interrupt List, MS-DOS Interrupt List or INTER) is a comprehensive list of interrupts, calls, hooks, interfaces, data structures, CMOS settings, memory and port addresses, as well as processor opcodes for x86 machines from the 1981 IBM PC up to 2000 (including many clones), [1] [2] [nb 1] most of it still applying to IBM PC compatibles today.
