Install

NEC D3735/3781/3772 INSTALLATION GUIDE DEC. 92 REV. A

NOTES ON INSTALLATION
=====================

First install the drive with the components side to the bottom.
Connect the system power and interface cables to the drive
connectors. Both connectors are keyed and can only be connected one
way. The interface connector may not be keyed. In this case check
if the red edge of the interface cable is connected to the pin 1 of
the drive connector.

 After installing the hardware please turn on your computer system
 and run the setup program. Please identify which model has to be
 installing and use the NEC recommended drive parameter for the set up
 setting. For this purpose edit the logical parameters into the
 "User type 47/48". The IDE interface accept two drives
 (Master/Slave). For a dual drives installation jumper both drives.
 The Master/Slave operation is guranteed only with NEC disk products.
 In order to install DOS please run the DOS program FDISK and Format
 C:/s accordingly.
 In case of installation trouble please contact NEC hotline:
              Tel. 49/89/93006 708

Caution: IDE drives don't need a low level format. If a new low
level format become neccessary, please run only qualified programs
for IDE devices like WDFMT.EXE by use of physical parameters.
