Installation guide

Overview 1-3
DVI-I to VGA Connector Adaptor:
Each Radeon 7500 AGP card is supplied with a connector adaptor for use on the
DVI port so that a standard CRT or LCD monitor with GA interface can be
connected to the second port on the Radeon 7500 AGP. Tru64 UNIX and
OpenVMS require that the DVI-I to VGA connector adaptor supplied
with the card always be used. Support for the second port and its use with
Tru64 UNIX and OpenVMS will be available through optional 3D software and
license.
