5 Input/Output Interfaces 5.1 Introduction This chapter describes the standard (i.e., system board) interfaces that provide input and output (I/O) porting of data and specifically discusses interfaces that are controlled through I/O-mapped registers. The following I/O interfaces are covered in this chapter: ■ SATA interface (5.2) ■ Diskette drive interface (5.3) ■ Serial interfaces (5.4) ■ Parallel interface (5.5) ■ Keyboard/pointing device interface (5.6) ■ Universal serial bus interface (5.7) ■ Audio subsystem (5.8) ■ Network interface controller (5.9) 5.2 SATA Interfaces These systems provide one, three, or four serial ATA (SATA) interfaces that support tranfer rates up to 3.0 Gb/s and RAID data protection functionality. The SATA interface duplicates most of the functionality of the EIDE interface through a register interface that is equivalent to that of the legacy IDE host adapter. 5.2.1 SATA Programming The SATA interface is configured as a PCI device during POST and controlled through I/O-mapped registers at runtime. Non-DOS (non-Windows) operating systems may require using Setup (F10) for drive configuration. Technical Reference Guide www.hp.com 5-1
