Perc S300 Firmware Update

hi, im getting firmware version out of date:

Firmware Version 1.0.1-0021+00193000

Minimum Required Firmware Version 2.0.0-0162+00193000

Driver Version 2.0.0-0162

Storport Driver Version 6.1.7601.18386

 im getting a lot of failed drives lately.

What would be the correct process to upgrade firmware?  Do I need to update a driver first?

thanks

mike
