Specifications

Memory
A “not enough memory” message appears when you try to open a program.
m Quit any programs you aren’t using, then try again to open the program you
want. If that doesn’t work, restart the computer. Sometimes restarting
makes additional memory available.
m If you are using a RAM disk or a disk cache, reduce its size and then
restart the computer.
m Use extra space on your hard disk as virtual memory to increase the
amount of memory available for opening programs. (Use virtual memory
only when the power adapter is plugged in.) You can turn on virtual
memory in the Memory control panel.
m If you consistently want to open more programs than memory allows, you
can purchase a memory expansion card from your Apple-authorized dealer.
SCSI devices
You can’t turn on the computer after connecting a SCSI device.
m SCSI devices connected to your computer must be turned on before the
computer itself. Turn on the SCSI device(s) first, and then turn on the
computer.
The computer doesn’t recognize your SCSI devices.
m When connecting SCSI equipment, it is important to use the right cables
and the correct number and placement of cable terminators. Check the
cables and terminators in the SCSI chain and make sure that all cables are
firmly attached.
m The devices may be off. Check to make sure that they are plugged in and
turned on.
m When the computer is in SCSI disk mode, tap the Power On (
I
) key to
turn the PowerBook off, and then try to turn the computer on again.
m If the device is a disk drive, it may need to be initialized before you can use
it. See the instructions that came with the device.
