The present invention provides for a firmware description language for accessing firmware registers. Computer-readable media store a data structure representing a firmware description language that includes at least a blade type field containing a blade type value that represents a blade type and a register description field containing a one or more register configuration values for accessing a register at a blade of the blade type represented in the blade type field. In some embodiments, a computer system receives application instructions for accessing a firmware register. The computer system refers to the firmware description language to identify register attributes of the firmware register. The computer system generates low-level instructions for accessing the firmware register in accordance with register attributes referred to in the firmware description language. The computer system issues the low-level instructions for accessing the firmware register.
