7-16 Compaq Smart Array 431 Controller User Guide

If a Compaq IAES Controller is the only other controller installed in

the system, since it cannot be primary, the system must boot from the

Compaq Smart Array 431 Controller (controller order = First).

Partitioning

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

■ Any FAT partition cannot be larger than 2 GB (2048-MB) in size.

■ 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.

OS/2 may allow the creation of partitions beyond these specified boundaries,

but you should adhere to these limits to ensure proper functionality.

Booting OS/2 from a Smart Array 431 Controller

Drive

This section describes additional information on booting a system from a

Compaq Smart Array 431 Controller.

The CPQARRAY.ADD driver must always be present when booting from a

Smart Array 431 Controller (the Compaq IAES is not a bootable device).

If a Smart Array 431 Controller is the primary disk controller, edit the

CONFIG.SYS file and make sure the “BASEDEV=CPQARRAY.ADD” entry

in the file is the first BASEDEV entry present. This guarantees that the

CPQARRAY.ADD driver is the first ADD driver loaded and thus cause OS/2

to assign the first hard drive on the first Smart Array 431 Controller as the

boot drive. For example:

BASEDEV=CPQARRAY.ADD

BASEDEV=CPQ53CX.ADD

If OS/2 is booting from another controller, order the other controller first:

BASEDEV=AMSI02.ADD

BASEDEV=CPQARRAY.ADD
