I can’t access some of the memory on my computer.

m All computers set aside some memory for system overhead.

m If you want to open more programs than memory allows, you can use the

Memory control panel to decrease the size of the disk cache, or remove or

decrease the size of the RAM disk (if you’re using one). You can also have

a memory expansion card installed in your computer.

Problems with hardware

RAM or cache diagnostic error

I see a message that a problem was detected with RAM or cache memory.

m If you see this type of error message, take your computer to an Apple-

authorized service provider as soon as possible. Ignoring this condition

could lead to random errors and failure that could result in your losing

data. (Although the error message may not reappear, the problem detected

during the computer’s self-check probably has not gone away.)

External floppy disk drive

I can’t eject a floppy disk.

m The disk may be stuck. Restart the computer, holding down the button on

your trackpad. If the disk is not ejected, you can eject it manually.

Carefully insert the end of a straightened paper clip into the small hole

near the disk drive’s opening, and push firmly until the disk is ejected.

Insert the end of a

large, straightened

paper clip into

this hole.
