Enabling the IDE Drive on the Docking Station

If you have installed an IDE device (such as a hard disk drive or a CD-ROM drive) in the docking station, you must change the setting on your computer to enable the device. By default, your computer uses the primary IDE channel for the primary hard disk drive (Primary-Master) and the secondary IDE channel for a device in the UltraBay II (Secondary-Master). You cannot use the IDE device in the docking station in this default 2-channel default IDE mode.
To enable an IDE device in the docking station, you must change the default setting to either of the following:
3-channel IDE mode 2-channel IDE mode
In 3-channel IDE mode, you can still use the hot and warm plug or unplug functions. An additional IRQ for the third IDE channel is required.
In 2-channel IDE mode, you do not have to assign an extra IRQ. However, you will not be able to use hot and warm plug or unplug functions.
Note: If you change the IDE channel configuration, the drive letter
assignment may be changed.

Setting to 3-Channel IDE Mode

1
Open the ThinkPad Configuration program.
2
Click on the Docking Station ( ) button.
3
Change the IRQ value in IRQ Holder for PCI Steering to a
value other than IRQ 11 or 15 (IRQ 9 is recommended).
4
Select Enable IDE devices. Make sure the third IDE channel
is selected in the list box. By default, the third IDE is
automatically selected.

Installing the Various Versions of Windows 95

The following versions of Windows 95 are available for your ThinkPad 770:
Retail Release version ( Service Pack Version 1 ( OEM Service Release Version 2 ( OEM Service Release Version 2.1 (
The OSR0 is an off-the-shelf version of Windows 95 and is available at any retail store. The OSR1 version can be downloaded from the Microsoft Internet homepage (http://www.microsoft.com). OSR2, and OSR2.1 versions are available only as preloaded versions. Since your ThinkPad 770 incorporates several new devices that were not available when these versions of Windows 95 were announced, take special precautions when installing or reinstalling these versions.

Versions OSR0 and OSR1

1
Create a Windows 95 supplementary diskette using the Diskette Factory program (refer to “Installing Software for Windows 95” in the online book).
2
Make sure there is enough space in the hard disk to store the cabinet files and the installation programs (the required space may vary depending on the language of Windows 95).

Refer to the Windows 95 documentation and the instructions that appear on the screen to complete the installation.
8
If required, install the OSR1 version available from the Microsoft Internet homepage.
9
If required, remove all the files in the temporary directory and the directory itself after you complete the installation, to free the space on the hard disk.

Versions OSR2 and OSR2.1

If you don't have a CD-ROM version of OSR2 or OSR2.1, you should reinstall them by restoring the original preloaded image from the Recovery CD. Refer to “Recovering Lost or Damaged Software” on page 14.
If you have a CD-ROM version of OSR2 or OSR2.1, do the following:

Hints and Tips

Receiving Faxes or Mail in Suspend Mode

To receive incoming faxes or mail under OS/2, you must set the modem settings in the fax application to one of the following:
Hardware FIFO enabled Hardware Flow Control on UART 16550A modem
In OS/2 FaxWorks for example, select Utilities, Settings, Modem Type, and Use HW FIFO (16550A).
If you do not set your modem to one of these settings, you will not be able to receive an incoming fax or an incoming call in suspend mode.

Hot or Warm Docking to the SelectaDock III Docking Station

For Windows 95
You may not be able to hot- or warm-dock your computer to the SelectaDock III docking station when certain PCI cards, PnP ISA cards, and PCMCIA cards are installed in the docking station. If such a condition occurs, cold boot the system.

USB Port Considerations

For PCI Cards in the SelectaDock III Docking Station
When the setting of the USB port on your computer is enabled (the default setting), do not use a PCI Video Card and a PCI Network Card at the same time in the SelectaDock III docking station. Your system cannot boot if both cards are inserted.
For the USB Port Setting on the SelectaDock III Docking Station
Do not disable the USB Port on the SelectaDock III. If you disable it, the system may hang during a hot- or warm-dock or undock operation. If this occurs, cold boot the system for recovery.
18
Title: C79DKMST CreationDate: 08/19/97 17:47:41
If a USB Device is Disabled
If your computer tries to enter suspend mode and the request is rejected, the device in the USB port may be disabled. When this occurs, do a hot unplug and plug operation for the USB device.

Hot Plugging or Unplugging a PCMCIA Card

After your computer returns from standby mode to normal operation, you cannot perform hot plug and unplug operations for certain Network PCMCIA Cards in the docking station slots. Reboot the system to solve the problem.

Using a Second CardBus Card

When a CardBus card is already configured in your computer or in the docking station (SelectaDock III or PC Card Enabler), you must configure the second CardBus manually by using the Device Manager. To get to the Device Manager, click on the System icon in the Control Panel.

Changing Batteries during Battery-Powered Operation

When Switching from the Main Battery to the Secondary Battery
1
Insert the battery pack with the secondary battery into the UltraBay II.
2
Make sure that the bay eject lever is locked.
3
Wait until the discharge symbol ( ) moves from the main battery (1) to the second battery (2) icon in the indicator panel.
You can now remove the main battery from the battery bay.
When Changing or Removing the Secondary Battery
1
Unlock the UltraBay II.
2
Wait until the discharge symbol ( ) moves from the secondary battery (2) to the main battery (1) icon. It takes a few seconds.
You can now remove the secondary battery.

Using an External Condenser Microphone

The microphone/line-in jack supports the following type of microphones:
When you want to use an electret condenser microphone, you must use one that provides its own power source.

Using the NetMeeting Software

When you are hanging up a video phone call in NetMeeting, you may see a Windows exception error message; “An exception OE has occurred in VxD VWIN32( 1)...”. This message appears only when you are making a video phone call directly over the telephone line and after you use such data sharing tools as the whiteboard, file transfer, chat, and application sharing. When this error occurs, shut down Windows and restart your computer. This error does not occur when you are using the Intel Video Phone for Internet Video Conferencing software.
