Follow these steps to avoid having a storage PC Card eject at startup:
1 Open the Startup Disk control panel.
If you need instructions for opening the control panel, see “How do I make a
disk the startup disk?” in the Disks topic area of Mac OS Guide, available in
the Guide (h) menu.
2 Click the icon for the computer’s hard disk to select it.
3 Close the control panel.
The PC Card storage device will no longer eject at startup.
Using a zoom video PC Card
The lower PC Card slot in the PowerBook 3400 series computer has circuitry
for handling video signals, called “zoom video.” Some independent
manufacturers offer PC Cards to which you can provide a video signal or
which allow you to connect a video camera. The zoom video PC Card is a
Type II card; it can only be used in the lower slot (because the special
circuitry needed for video signals is located in that slot).
With a zoom video card in the lower PC Card slot, the PowerBook can display
video on the computer’s screen or on an external monitor. Video signals are
sent directly to the video controller, so that the computer can display full-
motion video while performing other tasks at the same time.
If you purchase a zoom video PC Card, be sure that it has software that works
with your PowerBook.
Using a PC Card modem
When you are using a PC Card modem, make sure you do the following:
1 Install the communications software you want to use, as well as any software that came
with your modem.
PC Card modems work with your communications software by providing
compatibility with a feature of your Macintosh PowerBook’s software called
the Communications Toolbox.
