The IA-32 architecture defines a 48-bit segmented address format, with a 16-bit segment number and a 32-bit offset within the segment. Segmented addresses are mapped to 32-bit linear addresses. Demand paging 32-bit linear addresses are virtual addresses rather than physical addresses; they are translated to physical addresses through a page table.
The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel. It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture.
MIT's Operating System Engineering course formerly used the original V6 source code. xv6 was created as a modern replacement, because PDP-11 machines are not widely available and the original operating system was written in archaic pre-ANSI C.
Support for CPUID can be checked by toggling bit 21 of EFLAGS (EFLAGS.ID) – if this bit can be toggled, CPUID is present.

LMDE 2 'Betsy' was a long-term support release based on Debian Jessie. [19] When LMDE 2 was released, it was announced that all LMDE users would be automatically upgraded to new versions of MintTools software and new desktop environments before they were released into the main edition of Linux Mint.
This article may require cleanup to meet Wikipedia's quality standards.The specific problem is: Active distributions composed entirely of free software (Dragora GNU/Linux-Libre, gNewSense, Guix System, LibreCMC, Musix GNU+Linux, Parabola GNU/Linux-libre, and Trisquel) need information in all sub categories, #General is complete.
The x32 ABI was merged into the Linux kernel for the 3.4 release with support being added to the GNU C Library in version 2.16. [ 14 ] In December 2018 there was discussion as to whether to deprecate the x32 ABI, which has not happened as of April 2023, [ 15 ] and has seen some new development in May 2024.
The Swift community maintains a version which adds support for the language. Free Pascal and the Lazarus IDE can use LLDB as backend for their own FpDebug engine. The LLDB debugger is known to work on macOS, Linux, FreeBSD, NetBSD and Windows, [4] and supports i386, x86-64, and ARM instruction sets. [5] LLDB is the default debugger for Xcode 5 ...
