1.0 Controller Ordering

The Controller ordering is determined by two factors :

1. 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 controller, etc. The slot in
which the controller is installed does not affect the loading order; only the order shown
in CONFIG.SYS affects the order.

2. Each ADD driver developed by Compaq will order its controllers in ascending order
based on the controller order assigned by the Compaq System Configuration Utility.

All controllers of the same type, for example Array Controllers or Fibre Channel
controllers, should be in consecutive order as a group. This rule must be followed for
the driver to function properly with other storage controllers configured in the system.
The Compaq System Configuration Utility does NOT automatically enforce this rule.

2.0 Partitioning

The following are the limitations of OS/2 on any computer system:

a) Any FAT partition cannot be larger than two GB (2048 MB) in size.

b) It is recommended that you do not exceed 8 GB for an HPFS boot partition.
If you exceed this size, it would be possible for the OS/2 system files to end up beyond
8 GB on the disk and this would prevent the ROM from loading them at boot time.
