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

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.
