如前所述，典型的系统包括VMIVME-7740，其驻留的闪存磁盘配置为次要IDE设备、连接到主要IDE接口的硬盘驱动器和连接到软盘接口的软盘驱动器。使用此配置，可能需要将任一IDE设备上的逻辑设备配置为可引导设备，从而允许通过BIOS功能设置屏幕选择引导顺序。使用此功能，用户可以使系统配置有多个操作系统（OS），然后可以通过将IDE逻辑设备分配为引导设备来选择这些操作系统。DOS实用程序FDISK通常用于配置硬盘驱动器上的分区结构。其他实用程序可用于执行此任务。PowerQuest的Partition Magic是一款受欢迎且功能强大的商用程序。以下评论与使用FDISK进行分区有关。注意：删除分区将擦除该分区中以前保存的所有数据。
As discussed earlier, a typical system consists of the VMIVME-7740 with its resident Flash Disk configured as the Secondary IDE device, a hard drive attached to the Primary IDE interface, and a floppy drive attached to the floppy interface. Using this configuration, it may be desirable to have a logical device on either IDE device configured as a bootable device, allowing the selection of the boot sequence via the BIOS Features Setup screen. Using this capability, a user could have a system configured with multiple operating systems (OS’s) that would then be selectable by assigning the IDE logical device as the boot device. The DOS utility FDISK is commonly used to configure the partition structure on a hard drive. Other utility programs are available for performing this task. Partition Magic by PowerQuest is a popular and capable commercially available program. Comments that follow pertain to partitioning efforts using FDISK. CAUTION: Deleting a partition will erase all the data previously held in that partition.
