Apple Macintosh Performa 570 series - Manual (Page 58)

Rebuild your desktop regularly
A process known as “rebuilding the desktop” helps your Macintosh keep
track of data on your startup disks. Although you usually use the hard disk in
your computer as a startup disk, you can also start up from any other disk that
has system software installed. It’s a good idea to rebuild the desktop of your
startup disks once a month or so.
To rebuild the desktop of a startup disk, follow these steps:
1 Hold down the Option and
x
keys while you start up your computer.
Do not release the keys until you see a message asking whether you want to
rebuild the desktop.
2 Click OK.
