       mach32info - read out configuration information of a Mach32

       mach32info {info|force}

       mach32info  prints  out almost all the info about your mach32 card from configuration registers and Mach32 EEP-
       ROM. It also measures the Mach32 clocks. A completely idle system is required when these measurements are being
       performed. During these measurements, the video signals will be screwed up for about 3-4 seconds.

       If  your  monitor  does not switch off when getting a video signal it can't stand (fixed freq. monitors) better
       switch it off before starting mach32info. Your computer will beep when it is finished probing.  You  can  redi-
       rect the 'stdout' of mach32info to some file for viewing the results easier or mailing them.

       Do not redirect 'stderr' as you won't hear the beep.

       This  tool  is  part  of  svgalib.  Although it's output maybe useful to debug Xfree86 Mach32 Servers, I am NOT
       related to Xfree86!  Please do not send me (Michael Weller) any Xfree86 bug reports!  Thanx in advance.

       Note that this tool comes without any warranty!  Use it at your own risk!

       Warning, this tool does not check for VC changes etc.. Just let it run in its own virtual console as  root  and
       don't try to fool it.  Actually this is due to it not using svgalib at all but simply accessing the Mach32.

       Please  report  any  problems  with  running  mach32info  or with configuring the svgalib(7)'s Mach32 driver to
       Michael Weller <>.  Include the results from running this test with your report.

       info   print out the configuration information. Without info mach32info prints a usage message (looking  almost
              like this manpage ;-)).

       force  The  force  option  disables  the  sanity check that tries to detect the presence of the mach32 prior to
              printing the information.

              Do not use this option unless you are really, really sure that you have a  Mach32  compatible  vga  card

       This  utility is part of svgalib and can be found in the mach32/ subdirectory of the original svgalib distribu-
       tion. However, it is not installed by default, s.t. it is unclear where you can find it  if  your  svgalib  was
       install by a linux distribution.

       In  case  of  any  such problem, simply get an svgalib distribution from the net. You don't need to install it.
       Just make in the mach32/ subdirecty. As of this writing, svgalib-1.2.12.tar.gz is the latest version and can be
       retrieved by ftp from at /pub/Linux/libs/graphics and at /pub/linux/sources/libs
       which will most probably be mirrored by a site close to you.
