高级配置前面的讨论基于使用格式化为每个设备一个大分区的IDE磁盘设备。某些应用程序可能需要使用多个分区。以下对这些分区的讨论包括在VMIVME-7750 IDE磁盘设备（包括驻留的闪存磁盘）上创建多个分区时必须遵循的特殊过程。分区可以是主分区或扩展分区。扩展分区可以进一步细分为逻辑分区。每个设备最多可以有四个主分区；其中之一可以是扩展分区。但是，如果创建了多个主分区，一次只能有一个分区处于活动状态。非活动分区中的数据不可访问。在创建分区方案之后，可以格式化分区以包含所需的文件系统。
Advanced Configuration
The previous discussion is based on using the IDE disk devices formatted as one large
partition per device. Some applications may require the use of multiple partitions.
The following discussion of these partitions includes special procedures that must be
followed to create multiple partitions on the VMIVME-7750 IDE disk devices
(including the resident Flash Disk).
Partitions may be either a primary or an extended partition. An extended partition
may be subdivided farther into logical partitions. Each device may have up to four
main partitions; one of which may be an extended partition. However, if multiple
primary partitions are created, only one partition may be active at a time. Data in the
non-active partitions are not accessible.
Following the creation of the partitioning scheme, the partitions can be formatted to
contain the desired file system.
