Refer to ThinkPad Features Online Help for the general information. This section contains some unique information associated with the Windows NT environment which is not included in the Online Help. ThinkPad Feature supports the following function depends on your system. Supported Function Applicable ThinkPad Models --------------------------- ------------------------------------------ Device Configuration and All ThinkPad model Setup Fuel Gauge monitor All ThinkPad model Personalization Editor All ThinkPad model Suspend/Resume All ThinkPad model Power Management Diskette Drive/CD-ROM drive 760E/760ED/760EL/760ELD only Warm swap in Ultra bay 2.1.6.2.1 Consideration of Suspend/Resume on ThinkPad ----------------------------------------------------- Suspend/Resume feature is supported on all ThinkPad model under Windows NT once you install the ThinkPad Utility or power management driver. However, if the system is connected to the docking station or when some PC Card is inserted in the PCMCIA slot, the suspend operation will set the system entering into STANDBY mode if the system is used with AC power mode. This is to avoid the problems such as communication link break or failure when the system is used with the network environment. If you set the suspend timer using the ThinkPad Utility with power mode settings, suspend will be initiated automatically after the time out value if no activity is detected by the system. However, if your computer has CD-ROM drive and enable "AutoRun" feature, computer will not enter into the suspend mode. You must disable CD-ROM AutoRun Feature if the timer suspend is required. To disable AutoRun feature, set the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom\ "Autorun: 0x1" --> change to "Autorun: 0" Autorun is enabled by the default on Windows NT 4.0. 2.1.6.2.2 FDD Drive/CD-ROM drive warm swapping on 760E ------------------------------------------------------ The ThinkPad PIIX IDE device driver loads the IDE device driver for the UltraBay. This UltraBay in the IBM ThinkPad provides the capability to use different devices such as a CD-ROM, diskette drive, disk drive or a battery. The first step in this section is to install the device driver ThinkPad PIIX IDE. Once the driver is successfully installed, the diskette drive in the UltraBay needs to be enabled. Up to this point the device residing in the ThinkPad's UltraBay is a CD-ROM used during the installation of Windows NT. The diskette drive is located in the FDD External Attachment Kit connected to the back of the ThinkPad. Therefore, NT only recognize the external diskette drive as the only and primary diskette drive in the system. To enable the internal diskette drive port (in the UltraBay) the Utility Diskette provides the command, TPFDD.EXE. This command is used at a C: prompt with two parameters: Command Result ------- ------- TPFDD I (I = Internal) Enables the diskette drive in the UltraBay as the primary diskette drive in the system. If two diskette drives are installed, one in the UltraBay and one in the FDD External Attachment Kit, then the UltraBay's diskette drive will be A: drive and the external diskette drive will become the B: drive. TPFDD E (E = External) Disable the diskette drive as the primary diskette drive in the UltraBay. TPSWAP.EXE is the another command available for NT 4.0. This command works together with the previous command, TPFDD. Once the diskette drive in the UltraBay is enabled, "warm swapping" may be possible by executing the command TPSWAP. TPSWAP E (E = Enable) Enables "warm swap" support which means UltraBay devices can be exchanged while the system is in suspend mode. When the keyboard is lifted the ThinkPad system enters suspend mode automatically. For example, during the suspend mode you may exchange a CD-ROM for a diskette drive or vice versa without having to reboot the system. This is called "warm" swapping. TPSWAP D (D = Disable) Disables "warm swapping". Installing the ThinkPad PIIX IDE driver --------------------------------------- 1. Start Windows NT 4.0 on your computer. 2. Close any active applications by double clicking on the upper left hand corner of the window. 3. Select "Control Panel", then select "SCSI Adapters" 4. From the SCSI Adapters window, select "Drivers" tab, then select "Add..." to add a new driver. 5. Insert ThinkPad Utility Disk into diskette drive and select "Have Disk..." The system will beep with the Install from Disk window. Select the "OK" button. 6. The Install Driver dialog box will appear. Select "IBM ThinkPad PIIX IDE Driver" and select "OK". 7. Windows NT prompts you to restart your computer before the new settings will take effect. Select "No" to proceed for the next steps. After the installation of the device driver PIIXIDE.SYS the next step consists of activating the diskette drive in the UltraBay. The files TPFDD.EXE and TPSWAP.EXE provide support for this feature. These two files are included in the ThinkPad Utility Disk. The following are the steps to activate the diskette drive in the UltraBay: 8. Select "Start", then "Programs, then, "MS-DOS" 9. Change to the A: drive 10. Type "TPFDD I" from the DOS command prompt This file activates the diskette drive port in the UltraBay side. This command is required only once as long as you keep using the diskette drive or CD-ROM in the UltraBay. To disable the internal diskette drive bring it to its default setting, execute the command "TPFDD E". 11. Type "TPSWAP E" from the MS-DOS command prompt. This enables the warm swap feature.

If it doesn't, select the Mwave MIDI Synthesizer entry in the list box, and then press OK. 4. Shutdown Windows NT and reboot. Using Control Panel to add the Mwave Modem ------------------------------------------ After installing the Mwave drivers and MIDI samples, you will need to tell Windows NT about your Mwave modem. Windows NT does not provide a way for the Mwave installation program to do this for you automatically, so you must use the Windows NT Control Panel to manually configure the communication port and add the modem. Step 1 is to configure the communication port. Once you've completed the first step, the Mwave Modem will then be recognized by Windows NT. You can then begin using communication applications that don't require Unimodem support. Use the ThinkPad Setup utility (for ThinkPad 755 computers) or ThinkPad Features program (for ThinkPad 760 computers) to select a COM port for your modem. Then use the Windows NT Control Panel to define the same port. If you are using a ThinkPad 755, follow these steps. Then move on to the COM port verification procedure. Step1: Configure ThinkPad COM port: ----------------------------------- 1. From the Windows NT Start menu, choose Programs -> ThinkPad Setup -> DSP. 2. Choose one of the COM ports shown in the Telephony Function box. A message appears if the COM port is already in use. 3. Choose the Save button. If you are using a ThinkPad 760, follow these steps. Then move on to the COM port verification procedure. 1. From the Windows NT Start menu, choose Programs -> ThinkPad -> ThinkPad Features. 2. Click on the Modem button. (It looks like a handset phone.) 3. In the Internal Modem dialog box, choose a COM port. 4. Click on the OK button. To verify the COM port that you have chosen, follow these steps: 1. From the Windows NT Start menu, choose Settings -> Control Panel. Then double-click the Ports icon. 2. Verify that the list of COM ports includes the COM port that you chose in your ThinkPad setup. If not, choose the Add button. If the port is listed, double-click it. 3. On the Advanced Settings dialog box, choose settings as shown in the following table: BASE I/O COM PORT PORT ADDRESS IRQ COM1 03F8 4 COM2 02F8 3 COM3 03E8 4 COM4 02E8 3 You must also select the FIFO Enabled checkbox. Notes: If you use PCMCIA modem cards together with Mwave modem, Mwave modem must be configured as COM2. Assign COM1 for PCMCIA modem card if you need the PCMCIA modem card concurrently used. 4. Choose the OK button. If you have made any changes, you must shut down and restart the com- puter in order for the changes to take effect. Step 2 is to use the Control Panel to add the modem. This will allow you to use communication applications that use the Unimodem facility of Windows NT, such as HyperTerminal and Dial-Up Networking. Step2: Add Mwave modem for communication applications: ------------------------------------------------------ a. From the Windows NT Start menu, choose Settings -> Control Panel. b. Double-click the Modems icon. c. If you don't already have a modem installed, you will immediately see the "Install New Modem" dialog. If you already have a modem installed, select the "Add..." button to open the "Install New Modem" dialog. d. Select the "Next" button. Windows NT will start searching for the modem. e. If successful, Windows NT will report that it has found a modem of type "IBM ThinkPad 28.8 Mwave Data Fax." If Windows NT fails to detect a modem, verify that your communication port was configured correctly in step 1, and then retry step 2. Remember that the changes you make using the "Ports" applet of Control Panel will not take effect until you restart Windows NT. f. Select the "Next" button and follow the remaining instructions provided by Control Panel. After completing step 2, you should be able to use your Mwave modem with all modem communication applications supported by Windows NT 4.0. 2.1.8.2 Tips for Mwave/DSP Feature program -------------------------------------------- Some useful hints/limitations are fully documented in README.TXT of Windows NT Mwave install disk1. Read this document for the details. o Currently, the following features are not provided: - Speaker phone/answering machine - SoundBlaster game support - Class-1 FAX o Suspending during MIDI/WAVE play may not recover properly after the system is resumed. Discontinue MIDI/WAVE play prior to entering Suspend Mode. o Setting the music option playing with Pinball Game causes the game to play slowly. Avoid setting this option. o Intermittent FAX receive problem with WinFax Pro 4.0 Infrequently (perhaps 1 in ten attempts), faxes incoming to a suspended ThinkPad, are not received correctly. Usually the problem will clear itself and if the fax is resent, it will be received correctly. If the application appears to hang with the WinFax Pro Status screen displayed, click CANCEL to reset the application. o Read FAQs about the each specific modem application/FAX application/ multimedia applications for more details. This information is documented in README.TXT in Windows NT Mwave Install Disk 1. 2.1.9 Using ThinkPad Infrared Features on Windows NT 4.0 -------------------------------------------------------- Infrared feature on Windows NT supports point-to-point IR communication with other ThinkPad computers or systems equipped with an infrared port. Windows NT infrared feature supports the Generic (IrDA 1.0) mode up to 115000 BPS. This mode is used when communicating with other IBM ThinkPad computers or the other vendor's notebook systems. As the typical serial IR applications, Windows NT Dial-Up Networking connecting the two computers via serial IR or TranXit for Windows NT from Puma Technology are available. 2.1.9.1 Installing Infrared Device Driver ---------------------------------------- To install the Windows NT IR driver, follow the following steps: 1. Logon Windows NT with administrator's password. 2. On desktop, select "Start", then select "Run..." 3. Insert Windows NT IR driver diskette into your diskette drive and type: A:INSTALL Then select "OK" to start installation. 4. Windows NT Setup screen appears on the screen. Follow the menu to proceed to install. 5. Restart your computer When the device driver is installed, infrared port is configured as COM1 (IRQ4/Base IO address 3F8h) serial device. This is the default setting. If your IR port is not enabled as COM1, loading the infrared driver will be failed. Check Windows NT Event Viewer if IR driver load is failed. To enable infrared port for COM1 on your computer, 1. Run ThinkPad Feature Program and enable IR device as COM1 2. Restart your computer Changing the infrared COM port number ------------------------------------- When you need to use IR port other than the default value (COM1) such as to change to COM2, then you need to manually change the configuration parameter of Windows NT registry as follows: Registry key area: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Serial\Parameters\InfraRedPort For COM2 setting: DisablePort: 1 DosDevices : COM2 Interrupt : 3 PortAddress: 2f8 If you change to COM1 again, set the following value. For COM1 setting: DisablePort: 1 DosDevices : COM1 Interrupt : 4 PortAddress: 3f8 When you modify the registry key/value, restart the computer. 2.1.8.2 Configure the Infrared Port for Dial-Up Networking --------------------------------------------------- To use the dial-up networking with serial IR, you need to configure the null-modem setting on Windows NT RAS setup menu. To setup the IR communication for dial-up networking, follow the steps below: 1. Double click "Network" icon on "Control Panel" 2. Click "Services" tab on "Network" and click "Add..." to select network service 3. As a network service, select "Remote Access Service" and click OK (This is the case if you have not installed Remote Access Service. ) 4. On "Install New Modem setup" menu, select: "Dial-Up Networking Serial Cable between 2 PCs" and proceed to finish the modem setup. 5. Make sure this serial cable COM port is already assigned for your infrared port Restart the computer when RAS setup is completed. When the computer is restarted, you can connect your computer to the RAS server using the infrared port if your RAS server is also configured for using infrared device. ------------------------------------------- 3.0. Known limitations with Windows NT 4.0 ------------------------------------------- o Currently, the following functions are not provided on Windows NT 4.0 - IBM MPEG-II (ThinkPad 760CD/760ED), enhanced video function such as video overlay/video capture features are not supported. o Following are the special consideration required on Windows NT 4.0 - When you use your ThinkPad with the battery mode, it is recommended to avoid using with the power mode setting of "Automatic". Power mode setting of "Automatic" enables the processor (CPU) clock control automatic but Windows NT is not designed to support the dynamic CPU clock control. When the system is used with the battery mode, set the power mode setting either to "High Performance" or "Customized" to avoid some potential problems. - Hibernation function is supported with the following limitations. If Windows NT system partition is created with NTFS, hibernation is not supported. Another limitation is if the system is booted using the hibernation file, the PCMCIA slot is not powered on. Shutdown and restart Windows NT to use the PCMCIA card. - When using audio feature on ThinkPad 365X/560 series, I/O address conflict may occur if Token Ring adapter card is used together. Change the base I/O address of either the Token Ring card (A20h) or the default audio device base I/O address (220h) using the ThinkPad Feature Program. - When ISA adapter card, such as network adapter card, is used with IBM docking unit, disable unused internal devices such as Mwave modem, IR to assign the IRQ for your specific ISA card. On ThinkPad 760 family, the default configuration for internal device occupies many IRQs that constrains allocation for the ISA cards in the docking unit. You are recommended to assign IRQ =7 for your ISA card if most of the internal devices must be used together, specifically used with IBM Dock-II environment. - The number of PCMCIA devices is limited. Supported PCMCIA devices are listed on the Microsoft Windows NT Hardware Compatibility List. To use a PCMCIA card, it must be inserted in the PCMCIA slot before Windows NT is started. Inserting or removing the card after Windows NT is started is not supported. Only cold insertion for PCMCIA cards is activated. - On all ThinkPad 760E series (760E/ED/EL/ELD), IRQ 15 can not be allocated for PCMCIA card because this IRQ is reserved for the internal use. Assign the different IRQ number for any PCMCIA card. - On ThinkPad 755CD/CDV, PCMCIA ATA storage cards are not recognized because the internal CD-ROM is used as the secondary IDE which conflicts with the resource allocated for PCMCIA IDE under Windows NT. - When you use a PCMCIA Hard Disk Card on ThinkPad 760CD/760LD, it needs to disable the CD-ROM/Second HDD in the UltraBay. - On ThinkPad 760E/ED/ELD/EL, PCMCIA ATA cards will not work if ATA card IRQ is set to IRQ=15. - When Adaptec SlimSCSI (APA-1460)PCMCIA card is used on ThinkPad 760E family, IRQ 11 is allocated for SlimSCSI card. But IRQ 11 is also reserved as the default interrupt number for the PCI devices. To avoid the conflict of the interrupt number, change the default 1st IRQ (IRQ11) to IRQ15 on PCI Device Setup menu/Docking Station Advanced Setup menu using the ThinkPad Feature Program. - When the Xircom Credit card adapter Ethernet+28.8K modem card is used in the PCMCIA slot located in the IBM Docking station (IBM Dock-II/Selecta Dock-I/II) or located in the port replicator, Ethernet communication performance is significantly degraded. Use the PCMCIA slot located in the system unit side when this card is required. - When the IBM PCMCIA Token Ring card is used together with ThinkPad 560, it may cause the slow performance when file transfer is activated using FTP GET command. In this case, avoid using the NT 4.0 standard Token Ring Driver (IBM Token Ring(ISA/PCMCIA) Adapter) but install the another Token Ring driver (Auto 16/4 Token Ring PC Card driver) which is available as TRCC1.EXE in PCCo. NT Web support page. When installing this driver, modify the PCMCIA Data Base Registry as follows: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Pcmcia\DateBase\IBM\ TOKENRING Driver:ibmtok --> change to "Driver:ibmtkpcm" - Windows NT supports IBM Dock-I, IBM Dock-II,IBM SelectaDock Base model 1 and IBM SelectaDock I/II. However, hot/warm docking is not supported. To use the device in the Docking station, you must only do cold docking for the docking devices.
