Standard Parallel Port (SPP) mode Enhanced Parallel Port (EPP) mode Extended Capabilities Port (ECP) mode
These three modes (and their submodes) provide complete support as specified for an IEEE 1284 parallel port.
5.5.1 Standard Parallel Port Mode
The Standard Parallel Port (SPP) mode uses software-based protocol and includes two sub-modes of operation, compatible and extended, both of which can provide data transfers up to 150 KB/s. In the compatible mode, CPU write data is simply presented on the eight data lines. A CPU read of the parallel port yields the last data byte that was written. The following steps define the standard procedure for communicating with a printing device: 1. The system checks the Printer Status register. If the Busy, Paper Out, or Printer Fault signals are indicated as being active, the system either waits for a status change or generates an error message. 2. The system sends a byte of data to the Printer Data register, then pulses the printer STROBE signal (through the Printer Control register) for at least 500 ns. 3. The system then monitors the Printer Status register for acknowledgment of the data byte before sending the next byte. In extended mode, a direction control bit (CTR 37Ah, bit <5>) controls the latching of output data while allowing a CPU read to fetch data present on the data lines, thereby providing bi-directional parallel transfers to occur. The SPP mode uses three registers for operation: the Data register (DTR), the Status register (STR) and the Control register (CTR). Address decoding in SPP mode includes address lines A0 and A1.
5.5.2 Enhanced Parallel Port Mode
In Enhanced Parallel Port (EPP) mode, increased data transfers are possible (up to 2 MB/s) due to a hardware protocol that provides automatic address and strobe generation. EPP revisions 1.7 and 1.9 are both supported. For the parallel interface to be initialized for EPP mode, a negotiation phase is entered to detect whether or not the connected peripheral is compatible with EPP mode. If compatible, then EPP mode can be used. In EPP mode, system timing is closely coupled to EPP timing. A watchdog timer is used to prevent system lockup. Five additional registers are available in EPP mode to handle 16- and 32-bit CPU accesses with the parallel interface. Address decoding includes address lines A0, A1, and A2.
5.5.3 Extended Capabilities Port Mode
The Extended Capabilities Port (ECP) mode, like EPP, also uses a hardware protocol-based design that supports transfers up to 2 MB/s. Automatic generation of addresses and strobes as well as Run Length Encoding (RLE) decompression is supported by ECP mode. The ECP mode includes a bi-directional FIFO buffer that can be accessed by the CPU using DMA or programmed I/O. For the parallel interface to be initialized for ECP mode, a negotiation phase is entered to detect whether or not the connected peripheral is compatible with ECP mode. If compatible, then ECP mode can be used. Ten control registers are available in ECP mode to handle transfer operations. In accessing the control registers, the base address is determined by address lines A2-A9, with lines A0, A1, and A10 defining the offset address of the control register. Registers used for FIFO operations are accessed at their base address + 400h (i.e., if configured for LPT1, then 378h + 400h = 778h). The ECP mode includes several sub-modes as determined by the Extended Control register. Two submodes of ECP allow the parallel port to be controlled by software. In these modes, the FIFO is cleared and not used, and DMA and RLE are inhibited.

5.5.4 Parallel Interface Programming
Programming the parallel interface consists of configuration, which typically occurs during POST, and control, which occurs during runtime.
Parallel Interface Configuration
The parallel interface must be configured for a specific address range (LPT1, LPT2, etc.) and also must be enabled before it can be used. When configured for EPP or ECP mode, additional considerations must be taken into account. Address selection, enabling, and EPP/ECP mode parameters of the parallel interface are affected through the PnP configuration registers of the LPC47B397 I/O controller. Address selection and enabling are automatically done by the BIOS during POST but can also be accomplished with the Setup utility and other software. The parallel interface configuration registers are listed in the following table:
Table 5-13. Parallel Interface Configuration Registers
Index Address Function 30h 60h 61h 70h 74h F0h F1h Activate Base Address MSB Base Address LSB Interrupt Select DMA Channel Select Mode Register Mode Register 2 R/W R/W R/W R/W R/W R/W R/W R/W Reset Value 00h 00h 00h 00h 04h 00h 00h
Parallel Interface Control
The BIOS function INT 17 provides simplified control of the parallel interface. Basic functions such as initialization, character printing, and printer status are provide by subfunctions of INT 17. The parallel interface is controllable by software through a set of I/O mapped registers. The number and type of registers available depends on the mode used (SPP, EPP, or ECP). Table 5-14 lists the parallel registers and associated functions based on mode.

Universal Serial Bus Interface
The Universal Serial Bus (USB) interface provides asynchronous/isochronous data transfers with compatible peripherals such as keyboards, printers, or modems. This high-speed interface supports hot-plugging of compatible devices, making possible system configuration changes without powering down or even rebooting systems. As shown in Figure 5-8, the USB interface is provided by the 82801 component. All systems provide as total of eight USB ports, two USB ports accessible at the front of the unit and six USB ports on the rear panel. The USB ports are dynamically configured to either a USB 1.1 controller or the USB 2.0 controller depending on the capability of the peripheral device. The 1.1 controllers provide a maximum transfer rate of 12 Mb/s while the 2.0 controller provides a maximum transfer rate of 480 Mb/s.

5.8.1 AC97 Audio Controller
The AC97 Audio Controller is a PCI device that is integrated into the 82801 ICH component and supports the following functions:
Read/write access to audio codec registers 16-bit stereo PCM output @ up to 48 KHz sampling 16-bit stereo PCM input @ up to 48 KHz sampling Acoustic echo correction for microphone AC'97 Link Bus ACPI power management

5.8.2 AC97 Link Bus

The audio controller and the audio codec communicate over a five-signal AC97 Link Bus (Figure 5-12). The AC97 Link Bus includes two serial data lines (SD OUT/SD IN) that transfer control and PCM audio data serially to and from the audio codec using a time-division multiplexed (TDM) protocol. The data lines are qualified by a 12.288 MHz BIT_CLK signal driven by the audio codec. Data is transferred in frames synchronized by the 48-KHz SYNC signal, which is derived from the clock signal and driven by the audio controller. The SYNC signal is high during the frame's tag phase then falls during T17 and remains low during the data phase. A frame consists of one 16-bit tag slot followed by twelve 20-bit data slots. When asserted (typically during a power cycle), the RESET- signal (not shown) will reset all audio registers to their default values.

5.8.3 Audio Codec

The audio codec provides pulse code modulation (PCM) coding and decoding of audio information as well as the selection and/or mixing of analog channels. As shown in Figure 5-13, analog audio from a microphone, tape, or CD can be selected and, if to be recorded (saved) onto a disk drive, routed through an analog-to-digital converter (ADC). The resulting left and right PCM record data are muxed into a time-division-multiplexed (TDM) data stream (SD IN signal) that is routed to the audio controller. Playback (PB) audio takes the reverse path from the audio controller to the audio codec as SD OUT data and is decoded and either routed through an equalizer or applied directly to the digital-to-analog converter (DAC). The codec supports simultaneous record and playback of stereo (left and right) audio. The Sample Rate Generator may be set for sampling frequencies up to 48 KHz. The integrated analog mixer provides the computer control-console functionality handling multiple audio inputs.

BIOS DMA Data Transfers Allows you to control how BIOS disk I/O requests are serviced. When Enable is selected, the BIOS will service ATA disk read and write requests with DMA data transfers. When Disable is selected, the BIOS will service ATA disk read and write requests with PIO data transfers. SATA Emulation Allows you to choose how the SATA controller and devices are accessed by the operating system. Separate IDE Controller is the default option. Up to 4 SATA and 2 PATA devices may be accessed in this mode. The SATA and PATA controllers appear as two separate IDE controllers. Use this option with Microsoft Windows 2000 and Windows XP. SATA 0 is seen as SATA Primary Device 0 SATA 1 (if present) is seen as SATA Secondary Device 0 Combined IDE Controller is the other option. Up to 2 PATA and 2 SATA devices may be accessed in this mode. The SATA and PATA controllers appear as one combined IDE controller. Use this option with Microsoft Windows 98 and earlier operating systems. PATA Primary Device 0 replaces SATA 1 PATA Primary Device 1 replaces SATA 3 IDE Controller Allows you to enable or disable the primary IDE controller. This feature is supported on select models only. Primary SATA Controller Allows you to enable or disable the Primary SATA controller.
Table 8-3 Setup Utility Heading Option Description Secondary SATA Controller Allows you to enable or disable the Secondary SATA controller. This feature is supported on select models only. DPS Self-Test Allows you to execute self-tests on ATA hard drives capable of performing the Drive Protection System (DPS) self-tests.
Storage (continued) Boot Order
This selection will only appear when at least one drive capable of performing the DPS self-tests is attached to the system.
Allows you to: Specify the order in which attached devices (such as a USB flash media device, diskette drive, hard drive, optical drive, or network interface card) are checked for a bootable operating system image. Each device on the list may be individually excluded from or included for consideration as a bootable operating system source. Specify the order of attached hard drives. The first hard drive in the order will have priority in the boot sequence and will be recognized as drive C (if any devices are attached).
MS-DOS drive lettering assignments may not apply after a non-MS-DOS operating system has started.
Shortcut to Temporarily Override Boot Order To boot one time from a device other than the default device specified in Boot Order, restart the computer and press F9 when the monitor light turns green. After POST is completed, a list of bootable devices is displayed. Use the arrow keys to select the preferred bootable device and press Enter. The computer then boots from the selected non-default device for this one time. Security Setup Password Allows you to set and enables setup (administrator) password.

Keyboard

C.1 Introduction
This appendix describes the HP keyboard that is included as standard with the system unit. The keyboard complies with the industry-standard classification of an enhanced keyboard and includes a separate cursor control key cluster, twelve function keys, and enhanced programmability for additional functions. This appendix covers the following keyboard types:
Standard enhanced keyboard. Space-Saver Windows-version keyboard featuring additional keys for specific support of the Windows operating system. Easy Access keyboard with additional buttons for internet accessibility functions.
Only one type of keyboard is supplied with each system. Other types may be available as an option. unit. The keyboard interface This appendix discusses onlyinthe keyboardInput/Output Interfaces. is a function of the system unit and is discussed Chapter 5,

C.2 Keystroke Processing

A functional block diagram of the keystroke processing elements is shown in Figure C-1. Power (+5 VDC) is obtained from the system through the PS/2-type interface. The keyboard uses a Z86C14 (or equivalent) microprocessor. The Z86C14 scans the key matrix drivers every 10 ms for pressed keys while at the same time monitoring communications with the keyboard interface of the system unit. When a key is pressed, a Make code is generated. A Break code is generated when the key is released. The Make and Break codes are collectively referred to as scan codes. All keys generate Make and Break codes with the exception of the Pause key, which generates a Make code only.
