MS-DOS安装镜像(DOS操作系统) v7.10最新版

经典的DOS系统有很多种，如PC-DOS、DR-DOS、FreeDOS等，但MS-DOS安装镜像(DOS操作系统)v7.10最新版是最多人使用也是最实用的一种。MS-DOS 7.10是目前功能最强大实用，且兼容性最好的DOS。ms-dos7.1启动盘全面支持大硬盘、大内存、长文件名（LFN）、FAT32分区、可能直接启动Win3.x/9x等特性。

MS-DOS组成模块

ms-dos安装版采用模块结构，它由五部分组成：ROM中的BIOS模块、IO．SYS模块、MSDOS．SYS模块、COMMAND.COM模块和引导程序。
1、基本输入出模块
BIOS是一组程序和参数表，其中程序部份是可以通过中断方式调用的一组驱动程序，参数给出外设的地址和参数。BIOS是计算机硬件和操作系统之间的接口，操作系统通过它来管理计算机硬件资源。
2、IO.SYS模块
IO.SYS是MS—DOS和ROMBIOS之间的接口程序。它和ROM BIOS一起完成系统设备的管理。
3、MSDOS.SYS
MSDOS．SYS用于实现文件管理，包括文件管理、目录管理、内存管理等功能。它以功能调用的形式实现用户和MS—DOS之间的程序级接口。
4、COMMAND.COM
COMMAND.COM的主要功能是负责接收、识别、解释和执行用户从键盘输入的MS-DOS命令。
5、引导程序
引导程序又叫“引导记录”，其作用是检查当前盘上是否有两个系统文件，若有系统文件则把DOS系统从磁盘装入内存。
