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.

|
|
These are the I/O port mapping offsets and bit assignments used
|
|
by Creative Labs in their implementation of the host interface for
|
|
the Matsushita CD-ROM drive. These may be different in the adapter
|
|
cards (including sound cards) made by other vendors.
|
|
It is unknown if the Creative interface is based on a reference design
|
|
provided by Matsushita (other interface vendors would similar or
|
|
identical if this was the case).
|
|
|
|
The drive is actually capable of some things that the Creative
|
|
interface doesn't implement, such as DMA and interrupts.
|
|
|
|
See matcd.h for defines related to the Matsushita drive itself.
