Switching Displays
You can press Fn+F5 to switch between built-in and external displays. However, you should avoid
switching while graphic-intensive applications are running, such as OpenGL applications. In some
situations, switching displays can cause video corruption or application shutdown.
Running in MS-DOS Mode
If you boot your computer into MS-DOS, power management features are not supported. You should
disable power management in BIOS Setup to prevent the computer from suspending. If the computer
suspends, it could be disrupted and you could lose data.
Windows 98
Using the Floppy Drive with a USB Cable
When you attach the floppy drive to the computer using a USB floppy cable, Windows 98 assigns a drive
letter greater than drive C, such as drive D. If Windows shows drive A or B, you cannot use these drives to
access the floppy drive. You must use drive D or other assigned letter to access the floppy drive attached
with the USB cable. However, if you insert the floppy drive in an expansion base, you can use drive A to
access the drive.
Swapping Plug-In Modules
In Windows 98, you should not remove or insert a plug-in module in the expansion base while the computer
is in Standby mode. Standby mode is indicated by a blinking power-mode light. If you installed
BayManager hot-swap software, you can click the taskbar icon and swap modules while the computer is
turned on--but if you swap modules in Standby mode, the computer may stop responding in certain
situations. You can also swap modules when the computer is shut down.
Using the Infrared Port
If you use the infrared port in Windows 98, you should follow these suggestions:
* After enabling the infrared port in BIOS Setup, follow any additional setup instructions in
c:\hp\Drivers\Ir\Readme.txt.
* If you have problems sending or receiving data, see the notes about infrared use in
c:\hp\Drivers\Ir\Readme.txt.
* If you need to use the Recovery CD to reinstall the factory software on your hard disk, disable the
infrared port in BIOS Setup. The system may not restart correctly if this port is enabled.
