Hardware Release Notes
6.10 ATI RADEON 7500 Graphics
GBLPAGFIL 8233 (GBLPAGFIL is in units of 8192-byte Alpha pages.)
6.10.2 DECW$OPENGLSHR_RADEON.EXE Renamed to
DECW$MESA3DSHR_RADEON.EXE
V8.2
The shareable library SYS$LIBRARY:DECW$OPENGLSHR_RADEON.EXE has
been renamed to SYS$LIBRARY:DECW$MESA3DSHR_RADEON.EXE to reflect
that this library was built from the Mesa 3D code base. The API and functionality
remain the same as in previous releases. The logical name DECW$OPENGLSHR
is defined to point to the shareable library using the new file specification.
6.10.3 Support Limitations
V7.3-2
The following functionality is not supported:
• S-Video output
• Digital output
• Dual-head operation
If you connect monitors to both the DVI port and the analog VGA (CRT) port,
you will get identical video output on both screens. This is called cloned
video. True dual-head operation, with independent video displays on each
port, will be supported in a future release.
6.10.4 Video Artifacts at High Refresh Rates
V8.2
At high resolutions (for example, 1920x1440 and 2048x1536) and high refresh
rates, and under heavy load conditions, video artifacts might occur on some
individual RADEON cards or monitors. If you see such artifacts, try using a
lower refresh rate.
6.10.5 OpenGL Supports IEEE Arithmetic Only
V8.2
The OpenGL library supports only IEEE floating point format; VAX floating point
is not supported. Use the /FLOAT=IEEE_FLOAT option to compile applications.
6.10.6 DECwindows Server Hangs When Output Is Written to the Graphics
Console (OPA0)
V8.2
If output is written to the graphics console (OPA0) after DECwindows has started,
the DECwindows server hangs and the screen freezes. Pressing CTRL/F2 allows
the DECwindows server to run again.
Instead of writing messages directly to OPA0, HP recommends using OPCOM
and the Console Window application to display messages that normally would be
written to the console. To enable this application, edit the command procedure
SYS$MANAGER:DECW$PRIVATE_APPS_SETUP.COM and add the following
global symbol definition:
$ DECW$CONSOLE_SELECTION == "WINDOW"
