How do I upgrade firmware for tape?

Hey all,

I have a tape library (HP Storageworks MSL4048) and within it I have 4 tape drives.

To view the status, operations and configuration, I simply go to an internal web address through a browser and reach something called HP Command View MSL.

In Command View, I have a firmware upgrade option for tapes with a browse button.

After researching my tape drive model, I found the download link on HPs site:

The problem is that its asking me to select an OS???

What do I do here? I am using the web console to perform the upgrade and as far as I know it doesnt run on any OS.......or does it? 

I never set this up originally so I have no idea how this works? Is command view installed on an OS or can one simply navigate to the management IP of the device as I am doing?

Any help would be appreciated.

Thanks
