IBM ThinkPad 770Z Manual

You can use the ThinkPad 770X User's Reference for the ThinkPad 770Z computer . This
supplement includes updated information for the User's Reference (part number 27L3407). Use this
information instead of the corresponding information in the User's Reference .
Single FDD support
Although the User's Reference states that several FDDs can be supported by the ThinkPad
computer, your computer can support only one FDD at a time. The FDD in the bay always takes
precedence over the external FDD. For example, in suspend mode, if you install an FDD in the bay
and attach an FDD externally, the computer recognizes the FDD in the bay after resuming.
This information also applies when you are using the docking station.
Software Selections CD
Although your User's Reference describes the ThinkPad Customization Center CD, and the Setup
Guide describes a ThinkPad Customization Center icon, your computer has a Software Selections
CD rather than the ThinkPad Customization Center CD, and there is no ThinkPad Customization
Center icon on the desktop. The Software Selections CD includes the preloaded software and
ThinkPad device drivers for Windows 98, Windows 95, and Windows NT. You can customize your
computer with this CD. To use the Software Selections CD, insert it into the CD-ROM or DVD
drive. The main menu appears. Follow the instructions on the screen. For more information, click
Help in the menu.

changed from Utility Diskette for DOS to Personalization Data Update Diskette .

about using the Recovery CD with the boot diskette in the User's Reference no longer applies.

The “Config” menu of Easy-Setup includes an Asset ID icon ( ), for a new radio-frequency ID
option that is supported in specified models. More details are provided in the option's user's guide.

docking station and the AC Adapter to a SelectaBase 770 port replicator.

Notice for using the external monitor
If you use the Both LCD and CRT Display function, the external monitor must support the same
resolution as that of your ThinkPad LCD.
If you are using an external monitor that does not support the maximum resolution of the ThinkPad
LCD (1024 X 768 for the XGA model, or 800 X 600 for the SVGA model), do not use Both LCD
and CRT Display.
Notice for using the Compact Smart Card
