An operating system such as MS-DOS can load additional device drivers, such as CD-ROM drivers, but needs all of the hardware drivers already loaded at startup.
诸如MS - DOS之类的操作系统可以加载其他设备驱动程序，例如CD - ROM驱动器，但是需要所有硬件驱动程序在启动时就已经加载上来了。
To determine the correct drive letter, assume the system boots to DOS without a CD-ROM driver, and that all drives have the file Allocation Table (FAT) file system.
要确定正确的驱动器号，应假定系统在没有CD - ROM驱动器的情况下启动DOS，并且所有驱动器都有文件分配表(FAT)文件系统。
