IBM Laptop 770Z User Manual

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.
