Keeping the computer from ejecting storage PC Cards at startup
If you have a storage PC Card, such as an SRAM card or an ATA hard disk, in
either slot, the card will be ejected when the computer starts up. To prevent
excessive wear on PC Card connectors and slots, you can use the Startup Disk
control panel to keep storage PC Cards from ejecting when you turn on the
computer. (Other types of PC Cards, such as a modem or Ethernet card, are
not ejected at startup.)
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.
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 2400c 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 that
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.
A selection of software for use with a zoom video PC Card is provided on
the CD-ROM disc that came with your computer, in the Additional
Software folder.
If you purchase a zoom video PC Card, be sure that it has software that works
with your PowerBook.
