Configuring x86 BootBIOS
Introduction
The BIOS utility allows you to change HBA parameters (such as topology, PLOGI retry timer and auto scan
setting) and configure boot devices.
• Default settings are acceptable for most installations.
• In the BIOS utility, press <d> to reset the selected adapter to default values.
• The default topology is auto topology with loop first. For FC-AL, each HBA has a default AL_PA
of 01 (Hex). Change this topology setting, if necessary, before configuring boot devices.
• All HBAs or boot drives can be configured to other AL_PAs than their default values.
• If more than one HBA is in the system with the same PCI bus number, and each has a boot drive
attached, the first PCI-scan HBA will be the boot HBA. The first HBA is usually in the lowest PCI
slot in the system. This information can be viewed from the BIOS utility.

Prerequisites
• x86 BootBIOS must be loaded and the bootup message enabled on at least one of the host bus
adapters in your system to run the BIOS Utility.
To start the BIOS utility to configure your adapters:
1. Turn on the computer.
2. Press <Alt E> immediately (within five seconds) when the x86 BootBIOS message displays to
