Adds support for non-Sound Blaster host adapters, including those
distributed by Reveal, Lasermate, IBM, Media Vision, Crystal and others.
The driver automatically senses the correct adapter type and you can
have both in the system at the same time.
(This change should eliminate a few complaints.)
Corrected bit-masking problem that prevented use on SB Vibra-16 boards.
Declared some internal data and functions static that should have been
that way all along.
Documentation changes reflect the new hardware support and change the
appearance version to 2.0.5 (was 2.1). Nice and tidy. :-)
Beta testers have verified functionality on SB16, Vibra-16, Media Vision
and Reveal adapters. -Wall still shows no warnings.

Things to do for the matcd driver 4-Jul-95
|
|
|
|
1. Someone wants to switch all drivers from disklabel and
|
|
its assorted mechanisms over to disk slicing and its mechanisms,
|
|
but I was unable to find any useful documentation on how to
|
|
implement the changes for a read-only, single-partition,
|
|
removable (ie, partition can change size) device.
|
|
So this will have to wait until after 2.1.
|
|
|
|
2. Support for reading R-W subcodes while playing audio. This would be
|
|
useful if you have any CD+G or CD+MIDI discs, but the demand for this
|
|
is pretty low, unless you like Karaoke. Someone will also have to
|
|
write a CD+G viewer for X. The code for the driver to add this is
|
|
pretty minor but there aren't any precedents on how to handle the
|
|
data transfer to the application.
|
|
|
|
3. Support for reading the ISBN and UPC labels. The ioctl structures
|
|
for these appear to be defined but no other driver seems to do this.
|
|
|
|
4. Multi-session support. There are two forms of this; what
|
|
Philips defined and what Kodak uses. This will be quite
|
|
complicated and will probably require changes in the filesystem
|
|
layer. The drive support for Kodak multi-session is known to work.
|
|
|
|
5. Multiple data tracks. My vision here was to add an ioctl
|
|
that caused a track offset to be inserted into block requests,
|
|
effectively shifting the base to the specified track. Very
|
|
easy to add but not a big deal since I have only two discs
|
|
in my collection that have multiple data tracks and I mastered
|
|
one of them.
|
|
|
|
6. A curses-based CD-Player app (ie, not X). I will probably do this
|
|
mainly for its value as a debugging tool. It was pretty annoying
|
|
not finding a single application that actually issued all the
|
|
defined ioctls, let alone any new ones.
|
|
|
|
If you feel the urge to work on one or more of these remaining items,
|
|
please contact the author first at bsdmail@nemesis.lonestar.org
|
|
to make sure the work hasn't already been done or started.
