mach32info(1)                 Svgalib User Manual                mach32info(1)


NAME

       mach32info - read out configuration information of a Mach32


SYNOPSIS

       mach32info {info|force}


DESCRIPTION

       mach32info prints out almost all the info about your mach32 card from
       configuration registers and Mach32 EEPROM. 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 redirect 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 <eowmob@exp-math.uni-
       essen.de>.  Include the results from running this test with your
       report.


OPTIONS

       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 installed.

       This utility is part of svgalib and can be found in the mach32/
       subdirectory of the original svgalib distribution. 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 sunsite.unc.edu at
       /pub/Linux/libs/graphics and tsx-11.mit.edu at /pub/linux/sources/libs
       which will most probably be mirrored by a site close to you.
