# IOFireWireSBP2ORB

Represents an SBP2 normal command ORB. Supplies the APIs for configuring normal command ORBs. This includes setting the command block and writing the page tables for I/O. The ORBs are executed using the submitORB method in IOFireWireSBP2Login.

## Declaration

```occ
class IOFireWireSBP2ORB : IOCommand
