一 DOS下光驱的正确配置光驱在DOS或WINDOWS 3.X下需要专用的驱动程序进行驱动,即后缀为SYS的一个文件,一般在CONFIG.SYS及自动批处理文件中自动完成,比如:CONFIG.SYS内容:DEVICEHIGH=C:CDROMCDMKE.SYS/D:CDN0000/P:320AUTOEXEC.BAT文件内容:C:DOSMSCDEX.EXE/D:CDNOOOO/M:20/L:D其中/D用来指明设备名称,/M是存储缓冲区数,/L指定分配给CD-ROM驱动器的第一个字母,计算机将从此字母往下查询,找到第一个可用的字母即分配给光盘驱动器,但必须在CONFIG.SYS文件中用LASTDRIVE命令指出足够的驱动器字母可用范围,否则将安装失败。使用/M参数分配缓存一般为10-20即可,太大时不仅占用更多的物理内存,而且其效率不会有明显改善,在DOS 6.X以上也可以利用
The correct configuration of a DOS drive Under the DOS or WINDOWS 3.X drive requires a dedicated driver to drive, that is, a suffix SYS file, usually in the CONFIG.SYS and automatic batch file auto-complete, such as: CONFIG. SYS Contents: DEVICEHIGH = C: CDROM CDMKE.SYS / D: CDN0000 / P: 320AUTOEXEC.BAT File Contents: C: DOS MSCDEX.EXE / D: CDNOOOO / M: 20 / L: D / D is used to indicate the device name, / M is the number of storage buffers, / L specifies the first letter assigned to the CD-ROM drive, and the computer will look down this letter to find the first available letter, assigned to However, you must use the LASTDRIVE command in the CONFIG.SYS file to indicate sufficient drive letter availability, otherwise the installation will fail. Use / M parameter allocation cache is generally 10-20 can be, not only take up more than the physical memory, and its efficiency will not be significantly improved in DOS 6.X or more can also be used
