|  | | | | | A ribbon cable and power connector attach to each hard disk, the power cable has 4 wires in it and is keyed so it cannot be installed wrong. The other end of the ribbon cable plugs into the SCSI controller itself. | | | | | | | | | Read the documentation that came with the hard disk to see how the jumpers are set, if you are installing one disk and no other SCSI devices, the jumpers can usually be removed so that it will be set to ID 0. Each SCSI device on the chain (ribbon cable) must have its own unique ID number, usually 0 through 7, with 7 being reserved for the controller itself. | | | | | | | | | The last physical device on the cable has to be terminated, depending on the device, either with a jumper or some type of resistor networks that are plugged in. This is very important. | | | | | | | | | NIC installation | | | | | | | | | Similar to the VGA card installation described previously. If there are any jumpers to be set, do it now and write the settings down. Read the installation manual that came with the card. | | | | | | | | | Sound card installation | | | | | | | | | See NIC installation, above. If you are setting jumpers, make sure you don't set two cards to the same resource (IRQ, DMA, or port address) keep all settings distinct. | | | | | | | | | At this point, you are ready to begin your Operating System installation, don't forget to connect the mouse, external speakers, and a network hookup, if you have these options installed. | | | | | | | | | 3.10.6 Troubleshooting a PC that Won't Boot | | | | | | | | | Connect at least the following four components to your PC each time you boot. | | | | | | | | | speaker | | | | | | | | | keyboard | | | | | | | | | floppy drive | | | | | | | | | monitor | | | | | | | | | What should a normal boot look and sound like? | | | | | | | | | First, LED's will illuminate everywhere the motherboard, the hard disks, the floppy drive, the case, the NIC, the printer, the CD-ROM, the speakers, the monitor, and the keyboard. | | | | |
