6-34 Installing the Operating System Drivers
Controller Ordering
The order in which the ADD driver appears in the CONFIG.SYS file determines how each type of controller is ordered, relative to other types of controllers.
Each type of controller that a single ADD driver controls will be grouped together. The first ADD driver to appear in the CONFIG.SYS file will have its controllers ordered first, the second ADD driver will have its controllers ordered after the first driver, and so on.
The slot in which the controller is installed does not affect the loading order; only the order shown in CONFIG.SYS affects the order.
Each ADD driver developed by Compaq places its controllers in ascending order based on the controller order assigned by the Compaq System Configuration Utility.
The following rules must be followed for the driver to function properly with other storage controllers configured in the system.
NOTE: These rules are not automatically enforced by the Compaq System
Configuration Utility. Follow them carefully when configuring the system.
1.All Compaq array controllers should be in consecutive order as a group. If booting from a Compaq Smart Array 3200 Controller, the statement BASEDEV = CPQARRAY.ADD must be present.
2.Since a Compaq IAES Controller cannot be primary if it is the only other controller installed in the system, the system must boot from the Smart Array 3200 Controller (controller order = First).
