PCI Vend_ID: 0x104c, Dev_ID: 0x3d07, Sub_Vend_ID: 0x1048. Combination card with PCI-PCI bridge chip, P2 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
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. 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. Hvis Vvis Fv Fh Fp Htot

Device Configuration
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
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.
MESSAGES
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. Applica-
tion 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 permissi-
ble 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.
FILES
The driver module, built into a kernel with the doconfig command.
