  • Page 24: Terminating Resistor

    3.2 The Terminating Resistor Since hard disks can be connected to the controller in a daisy-chain fashion, the drives have a resistor called a terminating resistor. The resistor can either be removed (Seagate, Micropolis and Miniscribe drives) or disabled (NEe 5146) so you can turn the terminator on and off, depending on the configuration of your computer.

  • Page 27: Section 4: Controller Configuration

    Section 4: Controller Configuration The positIOn of the jumper shunts at location SWI of the hard disk controller (model number EV-390 or EV-391) determines the physical characteristics of the drive(s) attached to the controller. These physical characteristics include very important drive specifications, such as the capacity (in megabytes), and how many heads and cylinders the drives have.

  • Page 28: Controller Description

    ST412 specification. Drives connected to the EV-392 MUST be RLL (2,7)-qualified. EVERDISK subsystems can also be delivered with the EV­ 390 controller. The function of the EV-390 is similar to the EV-391, but the EV-390 is a full-sized controller board that can also control up to four 360KB-capacity floppy disk drives in addition to controlling two hard disk drives.
