DESCRIPTION

       The  PowerStorm	4D10T,	Elsa GLoria, and IntraServer Combo cards are inexpensive graphics accelerators based on 3DLabs' Permedia2 graphics
       chip. Supported cards offer up to 8MB of video memory and a large range of video formats.

   Hardware Variants
       The following three configurations are supported: 8 MB of video memory.
       PCI Vend_ID: 0x104c, Dev_ID: 0x3d07, Sub_Vend_ID: 0x1011, Sub_Dev_ID: 0x4d10.  8 MB of video memory.
       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

       pulse.  Vbp    - Line-equivalent duration of the vertical back porch.

   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.
