How to install DOS 3.31 on 86Box?

-

Introduction

Originally 86-DOS, written by Tim Paterson of Seattle Computer Products, DOS was a rough clone of CP/M for 8086 based hardware. Microsoft purchased it and licensed it to IBM for use with Microsoft's IBM PC language products. In 1982, Microsoft began licensing DOS to other OEMs that ported it to their custom x86 hardware and IBM PC clones.

MS-DOS 3.31 was only sold through a few OEMs, mainly Compaq.

This version adds support for hard drives up to 512MB.

It also does not use as much conventional memory as DOS 4.x or later, making it a good choice for 8088/8086 based computers.
