Working Inside Your Computer 73
Installing Ultra ATA Drives
Your Macintosh can accommodate two internal 1-inch-high ATA devices in the U-shaped drive
carrier in drive position 3 in the computer. If your computer has one Ultra ATA drive, it sits in
the lower portion of this U-shaped drive carrier. You can install a second ATA device in the
upper part of the carrier.
The drive that came with your Macintosh is designated the “master drive” (sometimes called
“drive 0”). The ATA drive you add as a second drive is called the “slave drive” or “drive 1.”
1 Configure your drive as a slave drive by setting the appropriate jumpers. Contact your drive
manufacturer or consult the manufacturer’s Web site to determine the correct settings.
Note: Your Macintosh doesn’t work with Ultra ATA devices set for cable select mode.
