Slave. Use this configuration if the drive is the second drive in the system. The slave is drive 1 in the System Setup record.

Master/slave timing protocol. This protocol involves the communication between the computer and the disc drives during the power-on cycle only. The computer queries the master drive for the status of both drives. The slave must report its status to the master within a certain time period. If it does not respond in time or if it uses a response signal that the master does not acknowledge, the master tells the host that the slave has timed out, and the computer does not recognize the slave. The Seagate drive is shipped configured to work with other drives that comply with the ATA-standard master/slave timing protocol.

This setting allows the Seagate drive in the slave position to respond to some drives that use a different protocol. Try using this setting if the slave is not identified after power-on.

Dual-drive emulation. This feature allows you to make the most of the BIOS limitation by making the drive two logical drives for the computer. Each logical drive is assigned a drive type in System Setup using the maximum translation geome- try values the BIOS allows. Each logical drive must be parti- tioned and formatted. A second, physical drive cannot be attached to the hard disc controller. You cannot use dual-drive emulation with cable select.

Cable-select.Use this configuration if your computer uses cable-select.

Remote LED. If your computer uses a remote drive-activity LED, place the ground wire side of the connector, usually the black wire, on pin 13 (–) and the other side on pin 14 (+) of the options jumper block. The LED can be damaged if the cable is attached incorrectly.

The options jumper block accepts a 0.100-inch connector. It may be necessary to replace the current connector on the LED cable with a 0.100-inch connector.
