Appendix C KEYBOARD C. Appendix C KEYBOARD INTRODUCTION This appendix describes the Compaq 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.
Page 192: Figure C-1. Keystrokep
Appendix C Keyboard 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.
Page 193: Figure C-2. Keyboard -T O -S
C.2.1 TRANSMISSIONS TO THE SYSTEM The keyboard processor sends two main types of data to the system; commands (or responses to system commands) and keystroke scan codes. Before the keyboard sends data to the system (specifically, to the 8042-type logic within the system), the keyboard verifies the clock and data lines to the system.

Page 197: C.2.3 Keys
C.2.3 KEYS All keys generate a make code (when pressed) and a break code (when released) with the exception of the Pause key (pos. 16), which produces a make code only. All keys, again, with the exception of the Pause key, are also typematic, although the typematic action of the Shift, Ctrl, Alt, Num Lock, Scroll Lock, Caps Lock, and Ins keys is suppressed by the BIOS.
Page 198 Appendix C Keyboard C.2.3.2 Multi-Keystroke Functions Shift - The Shift key (pos. 75/86), when held down, produces a shift state (upper case) for keys in positions 17-29, 30, 39-51, 60-70, and 76-85 as long as the Caps Lock key (pos. 59) is toggled off.
Page 199 C.2.3.3 Windows Keystrokes Windows-enhanced keyboards include three additional key positions. Key positions 110 and 111 (marked with the Windows logo or in combination with other keys to perform specific “hot-key” type functions for the Windows operating system. The defined functions of the Windows logo keys are listed as follows: Keystroke Window Logo Window Logo + F1...

Page 204: Figure C-9. Scanner Elements
Appendix C Keyboard SCANNER DESCRIPTION The scanner keyboard, available as an option, integrates a scanner with a SpaceSaver Windows ’95 keyboard, providing the ability to scan hardcopy looseleaf documents for faxing or electronic storage. The scanner provides resolutions up to 400 dpi and 256 shades of gray and outputs through a standard serial interface to the system unit.
Page 205: C.3.1 Scanner Operation
C.3.1 SCANNER OPERATION The scanner requires minimum user interface for normal operation. Insertion of a sheet of hardcopy activates the scanner. Operating parameters such as resolution, brightness, and motor speed are programmable for optimum performance. Other characteristics such as gamma correction, modulation transfer function (MTF), image compression, and pixel normalization are optimized through the use of pre-computed tables that are downloaded for image correction and adjustments when necessary.

C.3.1.1 Resolution/Shade Depth The drive motor mechanism of the CIS supports a vertical resolution of 400 dpi. The CIS provides a maximum horizontal resolution of 200 dpi. These factors provide true spatial resolutions of 100 and 200 dpi. Using horizontal interpolation, pseudo 300 and 400 dpi spatial resolutions are possible.
Page 208: Table C-4. Scanner I/F Signals
Appendix C Keyboard C.3.2 SCANNER INTERFACE The scanner communicates with the system unit (host) using a serial port as the primary choice of connection. The scanner interface is adaptable to several types of host connections as shown in Table C-4 (unshaded portion describes standard scanner interface with Compaq system unit). Table C–4.
Page 209 C.3.2.1 Pnyb Mode In the parallel nibble or “Pnyb” mode, the scanner transfers scanned information to the system unit (host) four bits (a nibble) at a time using the P3..P0 signals, which conform to RS-232 voltage and timing specifications. The P3..P0 signals are mapped to bits <7..4> respectively of the Modem Status Register (primary address 3FEh).

Appendix E MATROX MILLENNIUM-II GRAPHICS CARD Appendix E Matrox Millennium-II Graphics Card INTRODUCTION This appendix describes the Matrox Millennium-II Graphics Card used in some models. The Matrox Millennium-II Graphics Card is built by Compaq and based on the Matrox MGA- 2164Wgraphics controller and installs in the AGP slot on the system board.
Page 218: Figure E-2. Matrox Mga M
Appendix E Matrox Millennium II Graphics Card FUNCTIONAL DESCRIPTION The Matrox MGA Millennium-II Graphics Card installs in an AGP slot. The card is AGP- compliant. Operation of the AGP bus is almost identical to the PCI bus but operates at Host bus speed (i.e., in systems with the Pentium II 233, 266, or 300 processor the AGP bus operates at 66 MHz).
Page 219: Table
DISPLAY CONFIGURATIONS The Matrox Millennium-II graphics card directly supports standard CGA, EGA, and VGA modes. Using the supplied drivers, the Matrox Millennium graphics card supports the extended VGA modes listed in the following table. Unless otherwise indicated, all resolutions are supported by the video BIOS and the OS/2, Win3.1, WinNT3.1, Win95, and WinNT4.0 operating systems.
Page 220: Table
Appendix E Matrox Millennium II Graphics Card PROGRAMMING E.4.1 CONFIGURATION The Matrox Millennium-II graphics card works off the AGP bus and is configured through the MGA 2164W’s configuration space registers (listed in Table E-2) using PCI protocol. These registers are configured by BIOS during POST to the default configuration. Table E–2.
