Part VI Troubleshooting and Maintaining System Hardware

To set the drive as the Slave: Use a jumper to join the two pins that are labeled as Slave, or “SA.”

Cabling

IDE cables are 40or 80-pin ribbon cables. They can only go on one way on the hard drive or mainboard connector, with the designated pin 1 of the cable going to pin 1 of the connector. Most ribbon cables have a red stripe along the wire that designates it as pin 1.

Linux ATA/IDE Drive configuration

In Linux, the first IDE hard drive is given the device name of /dev/hda. The second drive is /dev/hdb. When partitioning the drives, the first partition of the first IDE drive is designated /dev/hda1, and so on.

Know how to install and configure ATA/IDE hard drives, including master/slave settings, jumpers, and cabling.

Linux Support for Other Devices

7.11 Identify proper procedures for diagnosing and troubleshooting peripheral devices

Support for newer technologies, such as IEEE 1394 and USB, can only come as fast as Linux developers and related project work can come up with drivers for these devices.

IEEE 1394 (Firewire)

This communications technology standard, sometimes called “Firewire” as trademarked by Apple and “iLink” as trademarked by Sony, is a serial bus that can run at up to 400 Megabits/sec. It is similar to a USB bus, but allows a SCSI command set to be sent over a standard IEEE 1394 bus. It is most often used for high speed peripherals, such as digital video cameras, CD writers, DVDs, optical drives, and scanners.

Linux has limited support for IEEE 1394 devices, and you must download special drivers to use them.

USB

The Universal Serial Bus (USB) is an advanced serial bus that can perform at speeds up to 12 MB/sec. Up to 127 devices can be connected using a series of USB hubs, which can connect up to 7 devices. USB is a hot pluggable and plug-and-play
