Chapter 4 SYSTEM SUPPORT 4.1 INTRODUCTION This chapter covers subjects dealing with basic system architecture and covers the following topics: ♦ ♦ ♦ ♦ ♦ ♦ ♦ PCI bus overview (4.2) AGP bus overview (4.3) System resources (4.4) System clock distribution (4.5) Real-time clock and configuration memory (4.6) System management (4.7) Register map and miscellaneous functions (4.
Chapter 4 System Support 4.2 PCI BUS OVERVIEW NOTE: This section describes the PCI bus in general and highlights bus implementation in this particular system. For detailed information regarding PCI bus operation, refer to the PCI Local Bus Specification Revision 2.2. These systems implement a 32-bit Peripheral Component Interconnect (PCI) bus (spec. 2.2) operating at 33 MHz. The PCI bus handles address/data transfers through the identification of devices and functions on the bus.
Technical Reference Guide Figure 4-1.
Chapter 4 System Support 4.2.1 PCI BUS TRANSACTIONS The PCI bus consists of a 32-bit path (AD31-00 lines) that uses a multiplexed scheme for handling both address and data transfers. A bus transaction consists of an address cycle and one or more data cycles, with each cycle requiring a clock (PCICLK) cycle.
Technical Reference Guide Two types of configuration cycles are used. A Type 0 (zero) cycle is targeted to a device on the PCI bus on which the cycle is running. A Type 1 cycle is targeted to a device on a downstream PCI bus as identified by bus number bits <23..16>.
Chapter 4 System Support The register index (CF8h, bits <7..2>) identifies the 32-bit location within the configuration space of the PCI device to be accessed. All PCI devices can contain up to 256 bytes of configuration data (Figure 4-3), of which the first 64 bytes comprise the configuration space header. 31 24 23 16 15 8 7 Register Index 0 31 24 23 16 15 8 7 0 FCh Device-Specific Area Device-Specific Area 40h 3Ch 38h 34h 30h 2Ch 28h Min. Lat. Min. GNT Int. Pin Int.
Technical Reference Guide 4.2.2 PCI BUS MASTER ARBITRATION The PCI bus supports a bus master/target arbitration scheme. A bus master is a device that has been granted control of the bus for the purpose of initiating a transaction. A target is a device that is the recipient of a transaction. The Request (REQ), Grant (GNT), and FRAME signals are used by PCI bus masters for gaining access to the PCI bus.
Chapter 4 System Support 4.2.3 OPTION ROM MAPPING During POST, the PCI bus is scanned for devices that contain their own specific firmware in ROM. Such option ROM data, if detected, is loaded into system memory’s DOS compatibility area (refer to the system memory map shown in chapter 3). 4.2.4 PCI INTERRUPTS Eight interrupt signals (INTA- thru INTH-) are available for use by PCI devices. These signals may be generated by on-board PCI devices or by devices installed in the PCI slots.
Technical Reference Guide 4.2.7 PCI CONFIGURATION PCI bus operations require the configuration of certain parameters such as PCI IRQ routing, DMA channel configuration, RTC control, port decode ranges, and power management options. These parameters are handled by the LPC I/F bridge function (PCI function #0, device 31) of the ICH2 component and configured through the PCI configuration space registers listed in Table 4-4. Configuration is provided by BIOS at power-up but re-configurable by software.

Technical Reference Guide 4.3 AGP BUS OVERVIEW NOTE: For a detailed description of AGP bus operations refer to the AGP Interface Specification Rev. 2.0 available at the following AGP forum web site: http://www.agpforum.org/index.htm The Accelerated Graphics Port (AGP) bus is specifically designed as an economical yet highperformance interface for graphics adapters, especially those designed for 3D operations.
Chapter 4 System Support 4.3.1.1 Data Request Requesting data is accomplished in one of two ways; either multiplexed addressing (using the AD lines for addressing/data) or demultiplexed (“sideband”) addressing (using the SBA lines for addressing only and the AD lines for data only). Even though there are only eight SBA lines (as opposed to the 32 AD lines) sideband addressing maximizes efficiency and throughput by allowing the AD lines to be exclusively used for data transfers.
Technical Reference Guide AGP 2X Transfers During AGP 2X transfers, clocking is basically the same as in 1X transfers except that the 66MHz CLK signal is used to qualify only the control signals. The data bytes are latched by an additional strobe (AD_STBx) signal so that an 8-byte transfer occurs in one CLK cycle (Figure 46). The first four bytes (DnA) are latched by the receiving agent on the falling edge of AD_STBx and the second four bytes (DnB) are latched on the rising edge of AD_STBx.
Chapter 4 System Support Figure 4-7. AGP 4X Data Transfer (Peak Transfer Rate: 1064 MB/s) 4.3.2 AGP CONFIGURATION AGP bus operations require the configuration of certain parameters involving system memory access by the AGP graphics adapter. The AGP bus interface is configured as a PCI device integrated within the north bridge (MCH, device 1) component. The AGP function is, from the PCI bus perspective, treated essentially as a PCI/PCI bridge and configured through PCI configuration registers (Table 4-6).

Chapter 4 System Support 4.4 SYSTEM RESOURCES This section describes the availability and basic control of major subsystems, otherwise known as resource allocation or simply “system resources.” System resources are provided on a priority basis through hardware interrupts and DMA requests and grants. 4.4.1 INTERRUPTS The microprocessor uses two types of hardware interrupts; maskable and nonmaskable.
Technical Reference Guide 8259 Mode The 8259 mode handles interrupts IRQ0-IRQ15 in the legacy (AT-system) method using 8259equivalent logic. Table 4-8 lists the standard source configuration for maskable interrupts and their priorities in 8259 mode. If more than one interrupt is pending, the highest priority (lowest number) is processed first. Table 4-8. Maskable Interrupt Priorities and Assignments Table 4-8.
Chapter 4 System Support The PCI interrupts can be configured by PCI Configuration Registers 60h..63h to share the standard ISA interrupts (IRQn). NOTE: The APIC mode is supported by the Windows NT and Windows 2000 operating systems. Systems running the Windows 95 or 98 operating system will need to run in 8259 mode. Maskable Interrupt processing is controlled and monitored through standard AT-type I/O-mapped registers. These registers are listed in Table 4-9. Table 4-9.
Technical Reference Guide The NMI Status Register at I/O port 061h contains NMI source and status data as follows: NMI Status Register 61h Bit 7 6 5 4 3 2 1 0 Function NMI Status: 0 = No NMI from system board parity error.
Chapter 4 System Support 4.4.2 DIRECT MEMORY ACCESS Direct Memory Access (DMA) is a method by which a device accesses system memory without involving the microprocessor. Although the DMA method has been traditionally used to transfer blocks of data to or from an ISA I/O device, PCI devices may also use DMA operation as well. The DMA method reduces the amount of CPU interactions with memory, freeing the CPU for other processing tasks. NOTE: This section describes DMA in general.
Technical Reference Guide The DMA logic is accessed through two types of I/O mapped registers; page registers and controller registers. 4.4.2.1 DMA Page Registers The DMA page register contains the eight most significant bits of the 24-bit address and works in conjunction with the DMA controllers to define the complete (24-bit)address for the DMA channels. Table 4-11 lists the page register port addresses. Table 4-11. DMA Page Register Addresses Table 4-11.
Chapter 4 System Support DMA controller 1 can move up to 64 Kbytes of data per DMA transfer. DMA controller 2 can move up to 64 Kwords (128 Kbytes) of data per DMA transfer. Word DMA operations are only possible between 16-bit memory and 16-bit peripherals. The RAM refresh is designed to perform a memory read cycle on each of the 512 row addresses in the DRAM memory space. Refresh operations are used to refresh memory on the 32-bit memory bus and the ISA bus.
Technical Reference Guide 4.5 SYSTEM CLOCK DISTRIBUTION These systems use an Intel CK-type clock generator and crystal for generating the clock signals required by the system board components. Table 4-13 lists the system board clock signals and how they are distributed. Table 4-13. Clock Generation and Distribution Table 4-13. Clock Generation and Distribution Frequncy Source Destination 66, 100, or 133 MHz CK Processor, MCH 100 or 133 MHz CK DIMM sockets 66 MHz CK ICH2, AGP Graphics Cntlr.
Chapter 4 System Support 4.6 REAL-TIME CLOCK AND CONFIGURATION MEMORY The Real-time clock (RTC) and configuration memory (also referred to as “CMOS”) functions are provided by the 82801 ICH2 component and is MC146818-compatible. As shown in the following figure, the 82801 ICH2 component provides 256 bytes of battery-backed RAM divided into two 128-byte configuration memory areas. The RTC uses the first 14 bytes (00-0Dh) of the standard memory area.
Technical Reference Guide 4.6.2 CMOS ARCHIVE AND RESTORE During the boot sequence the BIOS saves a copy of NVRAM (CMOS contents, password(s) and other system variables) in a portion of the flash ROM. Should the system become un-usable, the last good copy of NVRAM data can be restored with the Power Button Override function. This function is invoked with the following procedure: 1. 2. With the unit powered down, press and release the power button.
Chapter 4 System Support BIOS function (refer to Chapter 8 for BIOS function descriptions). 4.7 SYSTEM MANAGEMENT This section describes functions having to do with security, power management, temperature, and overall status. These functions are handled by hardware and firmware (BIOS) and generally configured through the Setup utility. 4.7.1 SECURITY FUNCTIONS These systems include various features that provide different levels of security.
Technical Reference Guide 4.7.1.3 Cable Lock Provision These systems include a chassis cutout (on the rear panel) for the attachment of a cable lock mechanism. 4.7.1.4 I/O Interface Security The serial, parallel, USB, and diskette interfaces may be disabled individually through the Setup utility to guard against unauthorized access to a system. In addition, the ability to write to or boot from a removable media drive (such as the diskette drive) may be enabled through the Setup utility.
Chapter 4 System Support 4.7.2 POWER MANAGEMENT This system provides baseline hardware support of ACPI- and APM-compliant firmware and software. Key power-consuming components (processor, chipset, I/O controller, and fan) can be placed into a reduced power mode either automatically or by user control. The system can then be brought back up (“wake-up”) by events defined by the ACPI specification.

Chapter 4 System Support High and low thermal parameters are programmed into the ASIC by BIOS during POST. If the high thermal parameter is reached then the fan(s) will be turned on full speed and the Thermsignal will be asserted. The asserted Therm- signal can, with the proper software setup, be used by the 82801 ICH2 to initiate an AOL message for transmission over a network (refer to Network Interface Controller subsection in Chapter 5).

Technical Reference Guide Chapter 5 INPUT/OUTPUT INTERFACES 5. Chapter 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: ♦ ♦ ♦ ♦ ♦ ♦ ♦ ♦ 5.2 Enhanced IDE interface (5.2) Diskette drive interface (5.3) Serial interfaces (5.4) Parallel interface (5.
Chapter 5 Input/Output Interfaces Hard drives types not found in the ROM’s parameter table are automatically configured as to (soft)type by DOS as follows: Primary controller: drive 0, type 65; drive 1, type 66 Secondary controller: drive 0, type 68; drive 1, type 15 Non-DOS (non-Windows) operating systems may require using Setup (F10) for drive configuration. 5.2.1.1 IDE Configuration Registers The IDE controller is configured as a PCI device with bus mastering capability.
Technical Reference Guide 5.2.2 IDE CONNECTOR This system uses a standard 40-pin connector for the primary IDE device and connects (via a cable) to the hard drive installed in the right side drive bay. Note that some signals are re-defined for UATA/33 and higher modes, which require a special 80-conductor cable (supplied) designed to reduce cross-talk. Device power is supplied through a separate connector. Figure 5-1. 40-Pin Primary IDE Connector (on system board). Table 5–3.
Chapter 5 Input/Output Interfaces 5.3 DISKETTE DRIVE INTERFACE The diskette drive interface supports up to two diskette drives, each of which use a common cable connected to a standard 34-pin diskette drive connector. All models come standard with a 3.5-inch 1.44-MB diskette drive installed as drive A. The drive designation is determined by which connector is used on the diskette drive cable.
Technical Reference Guide 5.3.1 DISKETTE DRIVE PROGRAMMING Programming the diskette drive interface consists of configuration, which occurs typically during POST, and control, which occurs at runtime. 5.3.1.1 Diskette Drive Interface Configuration The diskette drive controller must be configured for a specific address and also must be enabled before it can be used.

Chapter 5 Input/Output Interfaces 5.4 SERIAL INTERFACE All models include two RS-232-C type serial interfaces to transmit and receive asynchronous serial data with external devices. The serial interface function is provided by the LPC47B357 I/O controller component that includes two NS16C550-compatible UARTs. Each UART supports the standard baud rates up through 115200, and also special high speed rates of 239400 and 460800 baud.
Technical Reference Guide 5.4.2 SERIAL INTERFACE PROGRAMMING Programming the serial interfaces consists of configuration, which occurs during POST, and control, which occurs during runtime. 5.4.2.1 Serial Interface Configuration The serial interface must be configured for a specific address range (COM1, COM2, etc.) and also must be activated before it can be used. Address selection and activation of the serial interface are affected through the PnP configuration registers of the LPC47B357 I/O controller.
Chapter 5 Input/Output Interfaces 5.4.2.2 Serial Interface Control The BIOS function INT 14 provides basic control of the serial interface. The serial interface can be directly controlled by software through the I/O-mapped registers listed in Table 5-9. Table 5–9. Serial Interface Control Registers Table 5-9. Serial Interface Control Registers COM1 Addr. 3F8h COM2 Addr.
Technical Reference Guide 5.5 PARALLEL INTERFACE The legacy-light models include a parallel interface for connection to a peripheral device that has a compatible interface, the most common being a printer. The parallel interface function is integrated into theLPC47B277 I/O controller component and provides bi-directional 8-bit parallel data transfers with a peripheral device.
Chapter 5 Input/Output Interfaces 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.
Technical Reference Guide 5.5.4 PARALLEL INTERFACE PROGRAMMING Programming the parallel interface consists of configuration, which typically occurs during POST, and control, which occurs during runtime. 5.5.4.1 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.
Chapter 5 Input/Output Interfaces 5.5.4.2 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).
Technical Reference Guide 5.5.5 PARALLEL INTERFACE CONNECTOR Figure 5-5 and Table 5-12 show the connector and pinout of the parallel interface connector. Note that some signals are redefined depending on the port’s operational mode. Figure 5-4. Parallel Interface Connector (Female DB-25 as viewed from rear of chassis) Table 5–12.

Technical Reference Guide Control of the data and clock signals is shared by the 8042and the keyboard depending on the originator of the transferred data. Note that the clock signal is always generated by the keyboard. After the keyboard receives a command from the 8042, the keyboard returns an ACK code. If a parity error or timeout occurs, a Resend command is sent to the 8042. Table 5-13 lists and describes commands that can be issued by the 8042 to the keyboard. Table 5–13.
Chapter 5 Input/Output Interfaces 5.6.2 POINTING DEVICE INTERFACE OPERATION The pointing device (typically a mouse) connects to a 6-pin DIN-type connector that is identical to the keyboard connector both physically and electrically. The operation of the interface (clock and data signal control) is the same as for the keyboard. The pointing device interface uses the IRQ12 interrupt. 5.6.
Technical Reference Guide 5.6.3.2 8042 Control The BIOS function INT 16 is typically used for controlling interaction with the keyboard. Subfunctions of INT 16 conduct the basic routines of handling keyboard data (i.e., translating the keyboard’s scan codes into ASCII codes).
Chapter 5 Input/Output Interfaces Table 5-15 lists the commands that can be sent to the 8042 by the CPU. The 8042 uses IRQ1 for gaining the attention of the CPU. Table 5–15. CPU Commands To The 8042 Table 5-15. CPU Commands To The 8042 Value 20h 60h A4h A5h A6h A7h A8h A9h AAh ABh ADh AEh C0h C2h C3h D0h D1h D2h D3h D4h E0h F0hFFh Command Description Put current command byte in port 60h. Load new command byte. Test password installed.
Technical Reference Guide 5.6.4 KEYBOARD/POINTING DEVICE INTERFACE CONNECTOR The legacy-light model provides separate PS/2 connectors for the keyboard and pointing device. Both connectors are identical both physically and electrically. Figure 5-7 and Table 5-16 show the connector and pinout of the keyboard/pointing device interface connectors. Figure 5-6. Keyboard or Pointing Device Interface Connector (as viewed from rear of chassis) Table 5–16. Keyboard/Pointing Device Connector Pinout Table 5-16.
Chapter 5 Input/Output Interfaces 5.7 UNIVERSAL SERIAL BUS INTERFACE The Universal Serial Bus (USB) interface provides asynchronous/isochronous data transfers of up to 12 Mb/s 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.

Technical Reference Guide Chapter 7 BIOS ROM 7. Chapter 8 BIOS ROM 7.1 INTRODUCTION The Basic Input/Output System (BIOS) of the computer is a collection of machine language programs stored as firmware in read-only memory (ROM). The BIOS ROM includes such functions as Power-On Self Test (POST), PCI device initialization, Plug ‘n Play support, power management activities, and the Setup utility.
Chapter 7 BIOS ROM 7.2 ROM FLASHING The system BIOS firmware is contained in a flash ROM device that can be re-written with BIOS code (using the ROMPAQ utility or a remote flash program) allowing easy upgrading, including changing the splash screen displayed during the POST routine. 7.2.1 UPGRADING Upgrading the BIOS is not normally required but may be necessary if changes are made to the unit’s operating system, hard drive, or processor. All BIOS ROM upgrades are available directly from Compaq.
Technical Reference Guide 7.2.2 CHANGEABLE SPLASH SCREEN NOTE: A corrupted splash screen may be restored by the user with the ROMPAQ software. Depending on system, changing (customizing) the splash screen is a function may only be available though Compaq PC Customization Services. The splash screen (image displayed during POST) is stored in the BIOS ROM and may be replaced with another image of choice by using the Image Flash utility (Flashi.exe).
Chapter 7 BIOS ROM 7.3 BOOT FUNCTIONS The BIOS supports various functions related to the boot process, including those that occur during the Power On Self-Test (POST) routine. 7.3.1 BOOT DEVICE ORDER The default boot device order is as follows: 1. 2. 3. 4. CD-ROM drive (EL Torito CD images) Diskette drive (A) Hard drive (C) Network boot The order can be changed in the ROM-based Setup utility (accessed by pressing F10 when so prompted during POST). 7.3.
Technical Reference Guide 7.3.3 MEMORY DETECTION AND CONFIGURATION This system uses the Serial Presence Detect (SPD) method of determining the installed DIMM configuration. The BIOS communicates with an EEPROM on each DIMM through the SMBus to obtain data on the following DIMM parameters: ♦ ♦ ♦ ♦ ♦ Presence Size Type Timing/CAS latency PC133 capability NOTE: Refer to Chapter 3, “Processor/Memory Subsystem” for the SPD format and DIMM data specific to this system.
Chapter 7 BIOS ROM 7.4 SETUP UTILITY The Setup utility (stored in ROM) allows the user to configure system functions involving security, power management, and system resources. The Setup utility is ROM-based and invoked when the F10 key is pressed during the time the F10 prompt is displayed in the lower right-hand corner of the screen during the POST routine. Highlights of the Setup utility are described in the following table.

These functions, designed to support intelligent manageability applications, are Compaqspecific unless otherwise indicated. Table 7-4. Client Management Functions (INT15) Table 7-4.
Technical Reference Guide To support Windows NT an additional table to the BIOS32 table has been defined to contain 32bit pointers for the DDC locations. The Windows NT extension table is as follows: ; Extension to BIOS SERVICE directory table (next paragraph) db db db dd dw db dd dw “32OS” 2 “$DDC” ? ? “$ERB” ? ? ; sig ; number of entries in table ; DDC POST buffer sig ; 32-bit pointer ; byte size ; ESCD sig ; 32-bit pointer ; bytes size The service identifier for client management functions is “$CLM.
Chapter 7 BIOS ROM 7.5.1 SYSTEM ID AND ROM TYPE Applications can use the INT 15, AX=E800h BIOS function to identify the type of system. This function will return the system ID in the BX register.
Technical Reference Guide 7.5.3 TEMPERATURE STATUS The BIOS includes a function (INT15, AX=E816h) to retrieve the status of a system’s interior temperature. This function allows an application to check whether the temperature situation is at a Normal, Caution, or Critical condition. 7.5.4 DRIVE FAULT PREDICTION The Compaq BIOS directly supports Drive Fault Prediction for IDE-type hard drives. This feature is provided through two Client Management BIOS calls.
Chapter 7 BIOS ROM 7.6.1 SMBIOS In support of the DMI specification the PnP functions 50h and 51h are used to retrieve the SMBIOS data. Function 50h retrieves the number of structures, size of the largest structure, and SMBIOS version. Function 51h retrieves a specific structure. This system supports SMBIOS version 2.3.
Technical Reference Guide 7.7 POWER MANAGEMENT FUNCTIONS The BIOS ROM provides three types of power management support: independent PM support; APM support, and ACPI support. 7.7.1 INDEPENDENT PM SUPPORT The BIOS can provide power management (PM) of the system independently from an operating system that doesn’t support APM (including DOS, Unix, NT & older versions of OS/2). In the Independent PM environment the BIOS and hardware timers determine when to switch the system to a different power state.
Chapter 7 BIOS ROM 7.7.1.2 Going to Sleep in Independent PM When a time-out timer expires, Standby for that timer occurs. System Standby When the system acquires the Standby mode the BIOS blanks the screen. Since the hard drive inactivity timer is in the drive and triggered by drive access, the system can be in Standby with the hard drives still spinning (awake). NOTE: The BIOS does not turn the fan(s) off (as on previous products).
Technical Reference Guide 7.7.2 ACPI SUPPORT This system meets the hardware and firmware requirements for being ACPI compliant. This system supports the following ACPI functions: ♦ ♦ ♦ ♦ ♦ ♦ ♦ PM timer Power button Power button override RTC alarm Sleep/Wake logic (S1,S3, S4 (Windows 2000), S5) C1 state (Halt) PCI Power Management Event (PME) 7.7.3 APM 1.2 SUPPORT Advanced Power Management (APM) is an extension of power management.
Chapter 7 BIOS ROM Table 7-6. APM BIOS Functions Table 7-6.
Technical Reference Guide 7.7.3.1 Staying Awake in APM There are two "Time-out to Standby" timers used in APM: the System Timer and the IDE had Drive Timer. System Timer In POST, the ROM enables a timer in the ICH2 that generates an SMI once per minute.
Chapter 7 BIOS ROM 7.7.3.2 Going to Sleep in APM There are three levels of system sleep in APM: System/Hard Drive Standby, System Suspend, and System Off. System/Hard Drive Standby System Standby is achieved only by a system timer time-out, at such time the following occurs: 1. 2. All APM-aware device drivers put their respective devices into “Device Standby.” The O/S makes a BIOS call to go into System Standby. NOTE: The BIOS ROM of these systems will not turn the fan(s) off as on previous systems).
Technical Reference Guide System OFF There are two ways to turn the system off: 1. 2. Software shut-down as directed by the O/S. This, being the normal procedure, allows a NIC driver to re-arm the NIC for a Magic Packet™ Press and hold the power button for longer than 4 seconds (not recommended unless necessary). 7.7.3.

Technical Reference Guide Appendix C KEYBOARD C. Appendix C KEYBOARD C.1 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. This appendix covers the following keyboard types: ♦ Standard enhanced keyboard.
Appendix C Keyboard 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.
Technical Reference Guide C.2.1 PS/2-TYPE KEYBOARD TRANSMISSIONS The PS/2-type keyboard 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. If the clock signal is low (0), the keyboard recognizes the inhibited state and loads the data into a buffer.
Appendix C Keyboard C.2.2 USB-TYPE KEYBOARD TRANSMISSIONS The USB-type keyboard sends essentially the same information to the system that the PS/2 keyboard does except that the data receives additional NRZI encoding and formatting (prior to leaving the keyboard) to comply with the USB I/F specification (discussed in chapter 5 of this guide). Packets received at the system’s USB I/F and decoded as originating from the keyboard result in an SMI being generated.
Technical Reference Guide C.2.3 KEYBOARD LAYOUTS Figures C-3 through C-8 show the key layouts for keyboards shipped with Compaq systems. Actual styling details including location of the Compaq logo as well as the numbers lock, caps lock, and scroll lock LEDs may vary. C.2.3.

Technical Reference Guide C.2.3.3 Easy Access Keyboards The Easy Access keyboard is a Windows Enhanced-type keyboard that includes special buttons allowing quick internet navigation. Depending on system, either a 7-button or an 8-button layout may be supplied. The 7-button Easy Access Keyboard uses the layout shown in Figure C-7 and is available with either a legacy PS/2-type connection or a Universal Serial Bus (USB) type connection.
Appendix C Keyboard C.2.4 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 with the exception of the Pause and Easy Access keys 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.
Technical Reference Guide C.2.4.2 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. If the Caps Lock key is toggled on, then a held Shift key produces the lower (normal) case for the identified pressed keys. The Shift key also reverses the Num Lock state of key positions 55-57, 72, 74, 88-90, 100, and 101.
Appendix C Keyboard C.2.4.4 Easy Access Keystrokes The Easy Access keyboards (Figures C-7 and C-8) include additional keys (also referred to as buttons) used to streamline internet access and navigation.
