mach32info(1) Svgalib User Manual mach32info(1)

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 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 <>. Include the results from running this test with your report.

print out the configuration information. Without info mach32info prints a usage message (looking almost like this manpage ;-)).
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 at /pub/Linux/libs/graphics and at /pub/linux/sources/libs which will most probably be mirrored by a site close to you.

svgalib(7), svgalib.mach32(7), vgagl(7), libvga.config(5).
