C H A P T E R 1 Introduction Configurations 1 The Macintosh PowerBook 520 and 540 computers are available in a total of six configurations, as shown in Table 1-1.
C H A P T E R 1 Introduction ■ The PowerBook Express Modem II, available in the U.S. and Canada, is a 14.4kbps fax/data modem; it supports the CCITT V.32bis and V.42bis standards as well as industry standard MNP5. The modem comes with an internal DAA module that is software reconfigurable for use anywhere in the world. In the country where it was purchased, the DAA accepts the standard telephone connector.
C H A P T E R 1 Introduction MacsBug Version 6.2.2 1 MacsBug version 6.2.2 does not work with the PowerBook 520 and 540 computers because it assumes that all MC68040 microprocessors have FPUs. This problem is corrected in newer versions of MacsBug. ◆ Sound Sample Rates 1 The PowerBook 520 and 540 computers provide sound sample rates of 22.05 kHz, 44.1 kHz, and 48 kHz. The 22.05 kHz sample rate is slower than the sample rate used in some older Macintosh models: 22.

C H A P T E R 3 I/O Features The pins on the hard disk connector are 0.5 mm square; pin spacing is 2 mm on centers, horizontal and vertical. Figure 3-2 shows the location of the connector by defining the distance from the edge of the drive to the center line of the nearest pin, which is pin 39.
C H A P T E R 3 I/O Features Signals on Connector J2 3 Table 3-5 shows the signal assignments for the internal hard disk connector (J2). Entries in the table are arranged the same way as the pins on the connector: pin 1 across from pin 2, and so on.
C H A P T E R 3 I/O Features Internal Floppy Disk Drive 3 The floppy disk interface is identical to those in previous PowerBook computers. The internal floppy disk drive is a 1.44 MB Apple SuperDrive. The drive is 15 mm high; it accepts either standard Macintosh disks or DOS floppy disks. Table 3-5 shows the signal assignments for the internal floppy disk connector.
C H A P T E R 3 I/O Features Trackpad 3 For their pointing device, the PowerBook 520 and 540 computers have a trackpad, an integrated flat pad that replaces the trackball used in previous PowerBook computers. The trackpad provides precise cursor positioning in response to motions of the user’s fingertip over the surface of the pad. A single button below the trackpad is used to make selections.

C H A P T E R 3 I/O Features Types of Displays Flat-panel displays come in two types: active matrix and passive matrix. Active matrix displays, also called thin-film transistor (TFT) displays, have a driving transistor for each individual pixel. The driving transistors give active matrix displays high contrast and fast response time. Passive matrix refers to a display technology that does not have individual transistors.
C H A P T E R 3 I/O Features display. With appropriate adapter cables, the external video port can also support a VGA display or a 800-by-600-pixel SVGA display. The external video interface is enabled by attaching a monitor and restarting the computer. During the boot process, ROM software tests the monitor sense lines and activates the video output system if a recognized monitor is attached. If no monitor is found, the video output system is deactivated to conserve power.
C H A P T E R 3 I/O Features Note The largest image the PowerBook 520 and 540 computers can display on a multiscan monitor is 832 by 624 pixels. ◆ With a multiscan monitor, the Monitors control panel allows the user to select from the different modes available. Similarly, with an SVGA monitor, the user can select either the 640-by-480-pixel display or the 800-by-600-pixel display.

C H A P T E R 3 I/O Features Serial Port 3 The PowerBook 520 and 540 computers have a standard Macintosh serial port for synchronous, asynchronous, or AppleTalk serial communication. The 8-pin mini-DIN connector on the back panel is the same as those on other Macintosh computers. Table 3-10 shows the signal assignments for the serial port.
C H A P T E R 3 I/O Features SCSI Connectors 3 The internal and external HDI-30 connectors are identical to those used in other PowerBook models. The SCSI portion of the Combo IC connects directly to the internal and external SCSI connectors and can sink up to 48 mA through each of the pins connected to the SCSI bus. The data and control signals on the SCSI bus are active low signals that are driven by open drain outputs.

It accepts a Friendlynet adapter for either AUI (thick) cable, thin cable, or 10baseT (twisted pair) cable.
C H A P T E R 3 I/O Features ADB Port 3 The Apple Desktop Bus (ADB) port on the PowerBook 520 and 540 computers is functionally the same as on other Macintosh computers. The ADB is a single-master, multiple-slave serial communications bus that uses an asynchronous protocol and connects keyboards, graphics tablets, mouse devices, and other devices to the PowerBook 520 and 540 computers. The custom ADB microcontroller drives the bus and reads status from the selected external device.
C H A P T E R 3 I/O Features The frequency response of the sound circuits, not including the microphone and speakers, is within plus or minus 2 dB from 20 Hz to 20 kHz. Total harmonic distortion and noise is less than 0.05 percent from 20 Hz to 20 kHz with a 1 V RMS sine wave input. The input signal-to-noise ratio (SNR) is 82 dB and the output SNR is 85 dB, with no audible discrete tones. The sound system includes a built-in microphone and two speakers as well as external audio input and output jacks.

C H A P T E R 4 Expansion Modules Signal Assignments on the DAA Connector 4 Table 4-15 lists the signals on the DAA connector. Entries in the table are arranged the same way as the pins on the connector: pin 1 across from pin 2 and pin19 across from pin 20. These signals are used only by the modem card and the DAA card.
C H A P T E R 4 Expansion Modules The signals MDM_DAA[5-0] are multipurpose I/O digital control and status lines that operate at CMOS logic levels. The signals MDM_TX_P, MDM_TX_N, MDM_RX_P, and MDM_RX_N are two differential pairs for receiving and transmitting analog signals between the modem and the DAA. The nominal impedance of each differential pair is 47 K in parallel with a transformer winding that has an inductance of 1.3 Henries.

C H A P T E R 5 Software This chapter describes the new ROM and system software features of the PowerBook 520 and 540 computers. ROM Software 5 The ROM software in the PowerBook 520 and 540 computers is based on the ROM used in previous PowerBook computers, with enhancements to support the many new features of these computers.
C H A P T E R 5 Software Power Manager Software 5 Changes to the Power Manager software include ■ power cycling and sleep mode for the MC68040 microprocessor ■ support for the new smart batteries ■ support for turning on and off power to the Ethernet interface In addition to those changes, the PowerBook 520 and 540 computers include a new public API for power management; it is described in Chapter 6, “Power Manager Interface.
C H A P T E R 5 Software PDS Support Software 5 As in the desktop Macintosh models, the PDS expansion card is treated like a NuBus expansion slot. The Slot Manager software looks for a configuration ROM on the PDS card and then treats the card like a NuBus expansion card. PDS cards with configuration ROM that conforms to the requirements described in Designing Cards and Drivers for the Macintosh Family, third edition, will work with the existing Slot Manager.
C H A P T E R 5 Software System Software 5 The PowerBook 520 and 540 computers are shipped with system software version 7.1. A new system enabler file is required in order to run System 7.1 on the PowerBook 520 and 540 computers. Identifying the PowerBook 520 and 540 Computers 5 The correct method for software to use to identify the Macintosh model it is running on is by using the Gestalt Manager routines.
C H A P T E R 5 Software The control strip has a tab on its unattached end. The user can drag the tab to adjust the length of the strip or hold down the Option key and drag the tab to move the strip to a new position. The user can hide the control strip, except for the tab, by clicking the tab. Clicking the tab when the control strip is hidden makes the control strip visible again.
C H A P T E R 5 Software Similarly, the PowerBook 520 and 540 computers treat the different scanning modes available on multiscan monitors as a family of settings from which the user can select by means of the Options dialog box in the Monitors control panel. New Control Panels 5 Several control panels are new or revised for the PowerBook 520 and 540 computers. Figure 5-2 shows the appearance of the new control panel icons.
C H A P T E R 5 Software Figure 5-3 PowerBook control panel in easy mode Figure 5-4 PowerBook control panel in custom mode In custom mode, the PowerBook control panel lets the user set the time delays in minutes until the computer dims the display, goes into sleep mode, and goes into shutdown mode. The user can also select processor cycling, which slows down the processor and saves power. PowerBook Setup Control Panel Figure 5-5 shows the PowerBook Setup control panel.
C H A P T E R 5 Software PowerBook Display Control Panel 5 Figure 5-6 shows the PowerBook Display control panel. Figure 5-6 PowerBook Display control panel The PowerBook Display control panel allows the user with an external video monitor to select video mirroring mode. In normal operation, an external monitor provides additional desktop space, as on any Macintosh computer with multiple displays.
C H A P T E R 5 Software Control Strip Control Panel 5 Figure 5-8 shows the Control Strip control panel. The user can hide or show the control strip by clicking the corresponding button in the control panel. Figure 5-8 Control Strip control panel AutoRemounter Control Panel 5 Figure 5-9 shows the AutoRemounter control panel.
C H A P T E R 5 Software Contents of Module Files 5 The only required resource in a module file is a resource containing the code necessary for the module to interact with the control strip. A module file may contain more than one code resource if it is to provide multifunctional support. In that case, each module in the file is loaded and initialized separately and treated as an independent entity.
C H A P T E R 5 Software statusRect statusPort A pointer to a rectangle defining the area that a module may draw within. A pointer to the control strip’s graphics port. This will be either a color or black-and-white graphics port depending on which PowerBook Model the control strip is running on. The result value returned by the module will vary depending on the message sent to it. Results for each message are described in the sections on the individual messages.
C H A P T E R 5 Software Message number Message name Description sdevMouseClick 6 User has clicked on the module’s display area sdevSaveSettings 7 Save any changed settings in thee module’s preferences file sdevShowBalloonHelp 8 Display a help balloon, if the module has one sdevInitModule 5 The sdevInitModule message is the first message sent to a module after the module has been loaded from its file.
C H A P T E R 5 Software sdevDontAutoTrack 1 sdevHasCustomHelp 2 sdevKeepModuleLocked 3 strip assumes that the module only displays status information with no user interaction. If this bit is set, the control strip highlights the module’s display and then calls the module to perform mouse tracking; this bit is usually set when, for example, a module has a pop-up menu associated with it.
C H A P T E R 5 Software bits in the result are reserved for future use by Apple and must be set to 0. The bits are defined as sdevResizeDisplay 0 sdevNeedToSave 1 sdevHelpStateChange 2 sdevCloseNow 3 If this bit is set, the module needs to resize its display. The control strip sends a sdevGetDisplayWidth message to the module and then update the control strip on the display. If this bit is set, the module needs to save changed settings to disk.
C H A P T E R 5 Software If the sdevDontAutoTrack bit is also set, the control strip draws the module’s display in its highlighted state and then sends the sdevMouseClick message to the module. If the sdevDontAutoTrack bit is not set, the control strip software tracks the cursor until the mouse button is released. If the cursor is still within the module’s display area, the control strip software sends the sdevMouseClick message to notify the module that a click occurred.
C H A P T E R 5 Software SBIsControlStripVisible 5 You can use the SBIsControlStripVisible routine to find out whether the control strip is visible. pascal Boolean SBIsControlStripVisible(); The SBIsControlStripVisible routine returns a Boolean value indicating whether or not the control strip is currently visible. It returns a value of true if the control strip is visible, or a value of false if it’s hidden.
C H A P T E R 5 Software SBOpenModuleResourceFile 5 You can use the SBOpenModuleResourceFile routine to open a module resource file. pascal short SBOpenModuleResourceFile(OSType fileCreator); The SBOpenModuleResourceFile routine opens the resource fork of the module file whose creator is fileCreator, and return the file’s reference number as its result. If the file cannot be found or opened, SBOpenModuleResourceFile returns a result of –1.
C H A P T E R 5 Software points to a Pascal string containing the name of the resource. The preferences parameter contains a handle to a block of data which will be written to the file. If either prefsResourceName or preferences has a nil value, SBSavePreferences does nothing and returns a result of paramErr. If the resource is successfully saved, SBSavePreferences returns a result of 0.
C H A P T E R 5 Software svAllSmallData 0x0000FF00 load small 16-by-16-pixel icons ('ics#', 'ics4', 'ics8') svAllMiniData load mini 12-by-12-pixel icons ('icm#', 'icm4', 'icm8') 0x00FF0000 These values may be OR-ed together to load combinations of icon sizes. SBGetDetachIconSuite returns an appropriate error code if it’s unsuccessful, or 0 if if was able to load the icon suite. Note that if none of the icons comprising the icon suite could be found, the call returns the error resNotFound.
C H A P T E R 5 Software The SBTrackSlider routine displays an unlabeled slider above the module’s display rectangle. You can use the slider for displaying and setting the state of an arbitrary parameter. The parameter ModuleRect contains a pointer to the module’s display rectangle; ticksOnSlider is the upper bounds of the value returned by the slider; and initialValue is the starting position (0 to ticksOnSlider–1). When the user releases the mouse button, SBTrackSlider returns the final position.
C H A P T E R 5 Software The SBDrawBarGraph routine draws a bar graph containing the number of segments specified by the barCount parameter in a module’s display area. If the value of barCount is less than or equal to 0, SBDrawBarGraph does nothing. The bar graph is drawn relative to the location specified by barGraphTopLeft. Figure 5-10 shows the way the point barGraphTopLeft determines the position of the bar graph.
C H A P T E R 5 Software SBModalDialogInContext 5 You can use the SBModalDialogInContext in place of ModalDialog routine to keep background applications from getting run while your modal dialog window is visible. pascal void SBModalDialogInContext(ModalFilterProcPtr filterProc, short *itemHit); The SBModalDialogInContext routine is a special version of ModalDialog that doesn’t allow background applications to get time while a modal dialog window is visible.

C H A P T E R 6 Power Manager Interface This chapter describes the new application programming interface (API) to the Power Manager control software. Developers who provide expanded control panel software for the PowerBook Duo 280 and 280c computers will no longer need access to the Power Manager’s internal data structures.
C H A P T E R 6 Power Manager Interface Checking for Routines 6 Before calling any of the Power Manager interface routines, it’s always a good idea to call the Gestalt Manager to see if it they’re present on the computer. The Gestalt Manager is described in Inside Macintosh: Overview. A new bit has been added to the gestaltPowerMgrAttr selector: #define gestaltPMgrDispatchExists 4 If that bit is set to 1, then the routines are present.
C H A P T E R 6 Power Manager Interface Table 6-1 Interface routines and their selector values Selector value Routine name 98 decimal hexadecimal PMSelectorCount 0 $00 PMFeatures 1 $01 GetSleepTimeout 2 $02 SetSleepTimeout 3 $03 GetHardDiskTimeout 4 $04 SetHardDiskTimeout 5 $05 HardDiskPowered 6 $06 SpinDownHardDisk 7 $07 IsSpindownDisabled 8 $08 SetSpindownDisable 9 $09 HardDiskQInstall 10 $0A HardDiskQRemove 11 $0B GetScaledBatteryInfo 12 $0C AutoSleepContro
C H A P T E R 6 Power Manager Interface PMSelectorCount 6 You can use the PMSelectorCount routine to determine which routines are implemented. short PMSelectorCount(); DESCRIPTION The PMSelectorCount routine returns the number of routine selectors present. Any routine whose selector value is greater than the returned value is not implemented. ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for PMSelectorCount is 0 ($00) in the low word of register D0.
C H A P T E R 6 Power Manager Interface mustProcessorCycle 3 hasReducedSpeed 4 dynamicSpeedChange 5 hasSCSIDiskMode canGetBatteryTime 6 7 canWakeupOnRing 8 The processor cycling feature must be left on (turn it off at your own risk). Processor can be started up at a reduced speed in order to extend battery life. Processor speed can be switched dynamically between its full and reduced speed at any time, rather than only at startup time. The SCSI disk mode is supported.
C H A P T E R 6 Power Manager Interface SetSleepTimeout 6 You can use the SetSleepTimeout routine to set how long the computer will wait before going to sleep. void SetSleepTimeout(unsigned char timeout); DESCRIPTION The SetSleepTimeout routine sets the amount of time the computer will wait after the last user activity before going to sleep. The value of SetSleepTimeout is expressed as the number of 15-second intervals making up the desired time.
C H A P T E R 6 Power Manager Interface SetHardDiskTimeout 6 You can use the SetHardDiskTimeout routine to set how long the computer will wait before turning off power to the internal hard disk. void SetHardDiskTimeout(unsigned char timeout); DESCRIPTION The SetHardDiskTimeout routine sets how long the computer will wait after the last use of a SCSI device before turning off power to the internal hard disk.
C H A P T E R 6 Power Manager Interface SpinDownHardDisk 6 You can use the SpinDownHardDisk routine to force the hard disk to spin down. void SpinDownHardDisk(); DESCRIPTION The SpinDownHardDisk routine immediately forces the hard disk to spin down and power off if it was previously spinning. Calling SpinDownHardDisk will not spin down the hard disk if spindown is disabled by calling SetSpindownDisable (defined later in this section).
C H A P T E R 6 Power Manager Interface DESCRIPTION The SetSpindownDisable routine enables or disables hard disk spindown, depending on the value of setDisable. If the value of setDisable is true, hard disk spindown will be disabled; if the value is false, spindown will be enabled. Disabling hard disk spindown affects the SpinDownHardDisk routine, defined earlier, as well as the normal spindown that occurs after a period of hard disk inactivity.
C H A P T E R 6 Power Manager Interface Before calling HardDiskQInstall, the calling program must set the hdQType field to #define HDPwrQType 'HD' /* queue element type */ or the queue element won’t be added to the queue and HardDiskQInstall will return an error. ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for HardDiskQInstall is 10 ($0A) in the low word of register D0. The pointer to the HDQueue element is passed in register A0.
C H A P T E R 6 Power Manager Interface DESCRIPTION The GetScaledBatteryInfo routine provides a generic means of returning information about the battery or batteries in the system. Instead of returning a voltage value, the routine returns the battery level as a fraction of the total possible voltage. Note New battery technologies such as NiCad (nickel cadmium) and nickel metal hydride (NiMH) have replaced the sealed lead acid batteries of the original Macintosh Portable.
C H A P T E R 6 Power Manager Interface The value of warningLevel is the battery level at which the first low battery warning message will appear. The routine returns a value of 0 in some cases when it’s not appropriate to return the warning level. The value of batteryLevel is the current level of the battery. A value of 0 represents the voltage at which the Power Manager will force the computer into sleep mode; a value of 255 represents the highest possible voltage.
C H A P T E R 6 Power Manager Interface ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for AutoSleepControl is 13 ($0D) in the low word of register D0. The Boolean value is passed in the high word of register D0. GetIntModemInfo 6 You can use the GetIntModemInfo routine to find out information about the internal modem.
C H A P T E R 6 Power Manager Interface ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for GetIntModemInfo is 14 ($0E) in the low word of register D0. The bit field to set is passed in the high word of register D0. SetIntModemState 6 You can use the SetIntModemState routine to set some parts of the state of the internal modem.
C H A P T E R 6 Power Manager Interface DESCRIPTION The MaximumProcessorSpeed routine returns the maximum clock speed of the computer’s microprocessor, in MHz. ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for MaximumProcessorSpeed is 16 ($10) in the low word of register D0. The processor speed value is returned in the low word of register D0.
C H A P T E R 6 Power Manager Interface ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for FullProcessorSpeed is 18 ($12) in the low word of register D0. The Boolean result is returned in the low byte of register D0. SetProcessorSpeed 6 You can use the SetProcessorSpeed routine to set the clock speed the microprocessor will use the next time it is restarted.
C H A P T E R 6 Power Manager Interface Note When the computer is in SCSI disk mode, the computer appears as a hard disk to another computer. ◆ ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E). The selector value for GetSCSIDiskModeAddress is 20 ($14) in the low word of register D0. The SCSI ID is returned in the low word of register D0. SetSCSIDiskModeAddress 6 You can use the SetSCSIDiskModeAddress routine to set the SCSI ID for the computer to use in SCSI disk mode.
C H A P T E R 6 Power Manager Interface DESCRIPTION The GetWakeupTimer routine returns the time when the computer will wake up from sleep mode. If the PowerBook model doesn’t support the wakeup timer, GetWakeupTimer returns a value of 0.
C H A P T E R 6 Power Manager Interface IsProcessorCyclingEnabled 6 You can use the IsProcessorCyclingEnabled routine to find out whether processor cycling is enabled. Boolean IsProcessorCyclingEnabled(); DESCRIPTION The IsProcessorCyclingEnabled routine returns a Boolean value of true if processor cycling is currently enabled, or false if it is disabled. ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E).
C H A P T E R 6 Power Manager Interface BatteryCount 6 You can use the BatteryCount routine to find out how many batteries the computer supports. short BatteryCount(); DESCRIPTION The BatteryCount routine returns the number of batteries that are supported internally by the computer. The value of BatteryCount returned may not be the same as the number of batteries currently installed. ASSEMBLY-LANGUAGE INFORMATION The trap is _PowerMgrDispatch ($A09E).
C H A P T E R 6 Power Manager Interface GetBatteryTimes 6 You can use the GetBatteryTimes routine to find out about how much battery time remains. void GetBatteryTimes (short whichBattery, BatteryTimeRec *theTimes); DESCRIPTION The GetBatteryTimes routine returns information about the time remaining on the computer’s battery or batteries.
