Introduction to LSI SAS Configuration Utility

The LSI SAS Configuration Utility is a BIOS ROM program that allows users to manage and configure their LSI IT Mode HBA cards. It provides a user-friendly interface to set up various settings, including boot options, controller properties, and SAS topology. The utility is accessed during the post process by pressing a specific key sequence. However, some users have reported that the utility does not load as expected, leading to difficulties in configuring their LSI cards. In the upcoming sections, we will explore the reasons behind this issue and provide guidance on resolving it.

Common Issues with Accessing LSI BIOS ROM Program

One of the most common issues reported by users is the inability to access the LSI BIOS ROM program. After pressing the designated key sequence to invoke the SAS Configuration Utility, the system either skips the utility entirely or proceeds to the boot sequence without loading it. This problem can occur when the system is configured to boot in UEFI mode instead of legacy BIOS mode. The UEFI mode restricts the ability of the BIOS ROM program to load, resulting in users being unable to access the utility. In the following sections, we will illustrate how to change the boot settings to legacy BIOS mode, allowing the LSI SAS Configuration Utility to load correctly.

Changing Boot Settings to Legacy BIOS Mode

To ensure the LSI SAS Configuration Utility loads properly, it is necessary to change the system's boot settings from UEFI mode to legacy BIOS mode. This change will enable the BIOS ROM program to activate during the post sequence. Please note that switching to legacy BIOS mode may impact the boot process and compatibility with certain operating systems that rely on UEFI mode. Thus, it is essential to consider the advantages and disadvantages before making this adjustment.

To change the boot settings, follow these steps:

1. Enter the system BIOS by pressing the specified key during startup.
2. Navigate to the boot settings section.
3. Locate the boot mode or boot configuration option.
4. Change the mode from UEFI to legacy BIOS.
5. Save the changes and exit the BIOS settings.

Upon reboot, the system will boot in legacy BIOS mode. You can now proceed to invoke the LSI SAS Configuration Utility by pressing the designated key sequence during the post process. The utility should load correctly, allowing you to configure and optimize your LSI IT Mode HBA card. However, if you prefer to boot in UEFI mode, there is an alternative method to access some utility features, which will be discussed in the next section.

Accessing LSI UEFI ROM Settings

If you wish to retain UEFI boot mode while still accessing certain features of the LSI SAS Configuration Utility, you can utilize the UEFI menu system. This method is applicable only if the LSI card also has a UEFI ROM. By accessing the device settings in the system BIOS, you can locate and select the LSI card's UEFI ROM. This will enable you to perform basic controller management tasks, such as viewing controller properties and specifying boot options if drives are connected. However, it is important to note that the UEFI interface may not provide access to all the advanced settings available in the BIOS ROM program. In the following section, we will compare the features of the two interfaces.

Comparing Features of BIOS ROM Program and UEFI Interface

The BIOS ROM program and the UEFI interface offer distinct features for managing and configuring LSI IT Mode HBA cards. While the UEFI interface allows basic control and boot settings, the BIOS ROM program provides more advanced options and customization capabilities. For example, the BIOS ROM program allows adjusting SAS topology, modifying timing settings, and accessing additional adapter properties. These features are not available in the UEFI interface. If you require fine-grained control or want to optimize your LSI card to its fullest potential, utilizing the BIOS ROM program is recommended. However, if you prefer the convenience of the UEFI menu system and do not require advanced configurations, the UEFI interface can be a viable option.

Adjusting SAS Topology and Advanced Adapter Properties

One of the key advantages of using the BIOS ROM program is the ability to adjust the SAS topology and access advanced adapter properties. The SAS topology refers to the configuration and arrangement of SAS devices connected to the LSI IT Mode HBA card. By leveraging the BIOS ROM program, users can view the SAS topology, including information about connected devices, their status, and available configurations. This level of visibility enables better management and troubleshooting of SAS infrastructure.

Additionally, the BIOS ROM program allows access to advanced adapter properties, such as timing settings. These settings enable fine-tuning of the card's performance and can significantly impact data transfer rates. Adjusting the timing settings based on specific requirements or system constraints can optimize the overall functionality of the LSI IT Mode HBA card.

It is important to note that while some configuration settings can be modified through the operating system using specific LSI tools, the BIOS ROM program offers a more comprehensive and convenient approach to adjusting these settings. Thus, utilizing the BIOS ROM program is recommended for users seeking maximum control and flexibility.

Using LSI Tools in the Operating System

In addition to the BIOS ROM program, LSI provides tools that allow users to adjust configuration settings from within the operating system. These tools are particularly useful for users who prefer to make changes without rebooting the system or accessing the BIOS settings. With the appropriate LSI tools installed, users can modify various properties of the LSI IT Mode HBA card through a user-friendly graphical interface or command-line interface.

Aside from convenience, using LSI tools in the operating system can also provide real-time feedback and immediate application of configuration changes. This can aid in performance optimization and simplifying administration tasks. However, it is important to note that not all configuration options available in the BIOS ROM program may be accessible through these tools. For comprehensive control and access to all features, utilizing the BIOS ROM program is still recommended.
