Part Number: 27L8686
ThinkPad 770Z
User's Reference and Setup Guide Supplement
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.
Ÿ 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.
Ÿ 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.
