4 Ultra ATA Drive Guidelines and Features 4.1 Ultra ATA Jumpers Ultra ATA drives are configured by means of jumper settings. Factory-installed drives ship with the jumpers preset to the cable-select mode; therefore, no jumper setting changes are required on factory preinstalled, replacement, or option drives. With cable-select, the drive is configured as either Master (Drive/Device 0) or Slave (Drive/Device 1) by its physical attachment to the cable.
Ultra ATA Drive Guidelines and Features Single-Drive Cable System Board Device 0 (master) Blue Face Black Face Two-Drive Cable System Board Blue Face Device 1 (slave) Gray Face Device 0 (master) Black Face On a two-drive cable, the Drive/Device 0 connector is always the farthest one from the system board connector and the Drive/Device 1 connector is always the closest to the system board connector. cables may be labeled “Drive 0” instead of “Device 0” and “Drive 1” instead of “Device ✎ Some 1”. 4.
Ultra ATA Drive Guidelines and Features 4.3.1 Device Classes In order to determine the best drive attach sequence, ATA/ATAPI drives are segregated into four different classes based upon the bandwidth demands they place on an ATA controller. The most demanding devices are in Class 1 and the least demanding are in Class 4.
Ultra ATA Drive Guidelines and Features The attach sequence rule may also be stated in table format: General Attach Sequence Rule* Sequence Description 1 The lowest class drive - bootable hard drive recommended. 2 If only two drives, the last drive goes here; otherwise the lowest class of the remaining drives. 3 If only three drives, attach the final drive here. If a fourth drive exists, attach the lowest class drive here.
Ultra ATA Drive Guidelines and Features Example 1: Three Device Installation Sample A system has three devices: Ultra ATA-100 hard drive, CD-ROM drive, and a DVD drive. Using the Device Class Table in Section 4.3.
