Option Description
QA-6ZRAA-H8 ATI RADEON 7500 graphics support software for hp Tru64 UNIX
QL-6ZRA9-AA Open3D PAK for ATI RADEON 7500 OpenGL support
The driver included with hp Tru64 UNIX V5.1B supports a single ATI RADEON 7500
card, 2D only, and does not support use of the DVI-I port. The optional support software
provides the following additional functions (for further details, features, and restrictions, see
the release notes provided with the kit):
Section 3.5 explains how to install this software.
Multihead (2D only)
Up to 4 ATI RADEON 7500 AGP and/or ATI RADEON 7500 PCI cards can be installed in
one of the supported configurations. Prior to plugging in more than one ATI RADEON
7500 card, you must make sure that your installed SRM console revision level is 6.4 or
above. When the driver detects more than one ATI RADEON 7500 in the system, DMA is
automatically disabled and no 3D is supported. When dual screen mode is enabled with
multiple cards, then only the primary card will have dual screen mode enabled. The SRM
console determines which card is the primary card.
Dual-screen
By default, an ATI RADEON 7500 appears as a single screen device with identical video
signals coming out both the DVI-I and VGA ports. If desired, you can configure your
system so that two screens are created with the signal of the first screen (:0.0) coming out
the VGA port and the signal of the second screen (:0.1) coming out the DVI-I port.
Configuring your system for two screens on the single ATI RADEON 7500 board is
referred to as "dual-screen" mode.
The DVI-I port may be connected only to a VGA monitor through the use of the DVI-I to
VGA connector adapter (p/n 209815-001).
