If you need to tell the ILO firmware version on a HP server there are several ways:

1. Open the HP survey/diagnostic utility, this application is installed on your c drive, the Compaq version creates a survey.txt file, the HP version creates an XML file survey (with the date) both of which summarize the system, it will include the operating system information, the model type and all the components - memory/network/processors/array controller/ILO etc.
2. Open the HP insight agents web page for the server: http://servername:2301, this will display the system health and all the firmware/system information
3. Connect to your ILO card either with a laptop and cross over cable or remotely log in to check.
4. Run the ILO firmware upgrade utility in Windows, the application will prompt you and say, current version 1.51, this version is 1.91b.
5. Reboot the server and you’ll see the Integrated lights out card start with the F8 option - this displays the firmware version (HP Integrated Lights Out, version 1.41…. press f8 to configure)

The latest version is currently 1.91B which includes some improvements and fixes for known issues.
