Page 62: Pci Bus Transactions
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. High performance is realized during burst modes in which a transaction with contiguous memory locations requires that only one address cycle be conducted and subsequent data cycles are completed using auto-incremented addressing.

Page 65: Pci Bus Master Arbitration
GREQ/GGNT NOTE: [1] Slim Desktop and Configurable Minitower models only. PCI bus arbitration is based on a round-robin scheme that complies with the fairness algorithm specified by the PCI specification. The bus parking policy allows for the current PCI bus owner (excepting the PCI/ISA bridge) to maintain ownership of the bus as long as no request is asserted by another agent.
Page 66: Option Rom Mapping
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.
Page 67: Pci Configuration
Chapter 4 System Support 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.

Page 69: Agp Bus Overview
AGP BUS OVERVIEW NOTE: The Small Form Factor system features an on-board AGP graphics adapter and does not provide an accessible AGP slot. All Slim Desktop and Configurable Minitower systems provide an AGP slot and may implement either an on-board AGP graphics adapter with a GPA/AIMM card or separate AGP graphics card.
Page 70 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.
Page 71 Chapter 4 System Support AGP 2X Transfers During AGP 2X transfers, clocking is basically the same as in 1X transfers except that the 66- MHz 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 4- 6).
Page 72: Agp Configuration
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 (GMCH, 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).

Page 74: System Resources

Page 75: Table 4-8. Maskable Interrupt
Chapter 4 System Support 8259 Mode The 8259 mode handles interrupts IRQ0-IRQ15 in the legacy (AT-system) method using 8259- equivalent 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.
Page 76: Non-Maskable Interrupts
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.
Page 77 Chapter 4 System Support The NMI Status Register at I/O port 061h contains NMI source and status data as follows: NMI Status Register 61h Function NMI Status: 0 = No NMI from system board parity error. 1 = NMI requested, read only IOCHK- NMI: 0 = No NMI from IOCHK- 1 = IOCHK- is active (low), NMI requested, read only...
Page 78: Direct Memory Access
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.
Page 79 Chapter 4 System Support 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.
Page 80 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.
Page 81: System Clock Distribution
NOTES: [1] Routed to on-board controller on Deslpro EN SFF. Routed to AGP slot on Slim Desktop and Configurable Minitower. Certain clock outputs are turned off during reduced power modes to conserve energy. Clock output control is handled through the SMBus interface by BIOS.
Page 82: Real-Time Clock And Configuration Memory
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.
Page 83: Cmos Archive And Restore
Chapter 4 System Support 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.

Page 117: Keyboard/Pointing Device Interface
Chapter 5 Input/Output Interfaces KEYBOARD/POINTING DEVICE INTERFACE The keyboard/pointing device interface function is provided by the LPC47B357 I/O controller component, which integrates 8042-compatible keyboard controller logic (hereafter referred to as simply the “8042”) to communicate with the keyboard and pointing device using bi-directional serial data transfers.
Page 118 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.
Page 119: Pointing Device Interface Operation
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.
Page 120 5.6.3.2 8042 Control The BIOS function INT 16 is typically used for controlling interaction with the keyboard. Sub- functions of INT 16 conduct the basic routines of handling keyboard data (i.e., translating the keyboard’s scan codes into ASCII codes). The keyboard/pointing device interface is accessed by the CPU through I/O mapped ports 60h and 64h, which provide the following functions: Output buffer reads Input buffer writes...

Chapter 8 BIOS ROM 8.6.1 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 2.3.1 and the following structure types: Type Data...
Page 174: Power Management Functions
POWER MANAGEMENT FUNCTIONS The BIOS ROM provides three types of power management support: independent PM support; APM support, and ACPI support. 8.7.1 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.
Page 175: System Standby
Chapter 8 BIOS ROM 8.7.1.2 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 performs two duties: Blanks the screen. Turns off Vsync (to reduce CRT heater voltage). 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).
Page 176: Acpi Support
8.7.2 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) 8.7.3 APM 1.2 SUPPORT Advanced Power Management (APM) is an extension of power management.

8.7.3.1 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. When the ROM gets the SMI it checks status bits in the ICH2 for activity at any of the following devices: Keyboard...
Page 179 Chapter 8 BIOS ROM 8.7.3.2 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: All APM-aware device drivers put their respective devices into “Device Standby.”...
Page 180: Usb Legacy Support
System OFF There are two ways to turn the system off: Press and hold the power button for longer than 4 seconds (not recommended unless absolutely necessary). 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™.

Appendix C KEYBOARD 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 197: Keystroke Processing
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 198: Ps/2-Type Keyboard Transmissions
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.
Page 199: Usb-Type Keyboard Transmissions
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).

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.
Page 203: Keys
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.
Page 204 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.
Page 205 Appendix C Keyboard 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. These buttons, which can be re-programmed to provide other functions, have the default functionality described below: 7-Button Easy Access Keyboard: Button # Description...
