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 Embeddable Linux Kernel Subset (ELKS), formerly known as Linux-8086, is a Linux-like operating system kernel.It is a subset of the Linux kernel, intended for 16-bit computers with limited processor and memory resources such as machines powered by Intel 8086 and compatible microprocessors not supported by 32-bit Linux.
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.
Linux, 386BSD and Windows NT were developed for the 386 because it was the first Intel architecture CPU to support paging and 32-bit segment offsets. The 386 architecture became the basis of all further development in the x86 series.
Debian Unstable, known as "Sid", contains all the latest packages as soon as they are available, and follows a rolling-release model. [6]Once a package has been in Debian Unstable for 2-10 days (depending on the urgency of the upload), doesn't introduce critical bugs and doesn't break other packages (among other conditions), it is included in Debian Testing, also known as "next-stable".
The updated instruction set is grouped according to architecture (i186, i286, i386, i486, i586/i686) and is referred to as (32-bit) x86 and (64-bit) x86-64 (also known as AMD64). Original 8086/8088 instructions
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] Neither it has happened as of May 2024, and even more, it got some new development. [16]
GNU Hurd is a collection of microkernel servers written as part of GNU, for the GNU Mach microkernel. It has been under development since 1990 by the GNU Project of the Free Software Foundation, designed as a replacement for the Unix kernel, [4] and released as free software under the GNU General Public License.
