Raw Blame History

/*
Linux-specific Information about the Hardware.
(C) Copyright 1998-2006 by Helge Deller <deller@gmx.de>
(C) Copyright 2006 by Jahshan Bhatti <jabhatti91@gmail.com> (CD-ROM Info)
To do (maybe?):
- include Information about XFree86 and/or Accelerated X
(needs to change configure-skript, to see, if Header-files are available !)
- maybe also include information about the video-framebuffer devices
- rewrite detection-routines (maybe not to use the /proc-fs)
- more & better sound-information
/dev/sndstat support added: 1998-12-08 Duncan Haldane (f.d.m.haldane@cwix.com)
