graphics device, and one or two ethernet controllers. The
graphics component has 4MB of video memory. PCI Vend_ID:
0x3d3d, Dev_ID: 0x0009.
Display Resolution [Toc] [Back]
The following table details the display resolutions that
are supported by these cards. Setting the resolution is a
task performed by the X Server and the associated documentation
should be read for the particulars of the mechanisms
used.
Note
Before setting a video mode, consult the documentation for
the monitor attached to the graphics adapter to verify
compatibility with the desired refresh rate and resolution.
Monitors can be damaged to the point of doing physical
damage to the monitor, other objects, and humans.

Device Configuration [Toc] [Back]
The comet driver supports up to 15 devices in a single
system. Prior releases of the system software supported
seven or fewer devices. Other software, such as the X
Server or base operating system, may put additional
restrictions on the number of units supported.
Device Description [Toc] [Back]
In PCI-based systems, no more than one VGA device can be
configured into the system. The comet cards typically have
a jumper or miniature switch to enable and disable VGA
operations.
Device driver messages are typically logged to /var/adm/
messages on UNIX systems. Should problems arise, this file
should be checked for informational messages. Some messages
of interest are: "comet0: %dx%d cursor glyph truncated
to hardware limits"
The X Server attempted to use a cursor larger than
the 64x64 limits of the hardware. Cursor glyph will
be displayed incorrectly. Application should be
brought into conformance with X11 expectations.
"comet0: Video pixel fifo underflowed during previous
video format"
The flow of pixel data from video memory to the
video DACs was exhausted possibly causing visual
artifacts on the display. It is permissible and
expected that this may occur once shortly after
booting when the device hasn't been configured. But
otherwise, this should be reported to your technical
support organization, including in the description
the video format currently in use as well as
the application running at the time.
The driver module, built into a kernel with the doconfig
command.
