/* AUTOHUNT Adds extra code that allows the driver to search
for interface cards rather than having to hard-code
the locations in the kernel /boot/device.hint file,
which is only read at boot-time.
Leaving AUTOHUNT enabled is the recommended setting.
*/
/*#define AUTOHUNT*/
/* NUMCTRLRS Configures support for between one and four host
interfaces, for up to 16 drives. The number of
entries in the kernel config file is used by default,
but this may be changed to a specific value if
desired. The number of controllers cannot exceed 4.
Setting the value smaller than four slightly reduces
the amount of memory used by the driver, but since
the driver is under 30K, it probably isn't worth
changing.
*/
#define NUMCTRLRS 4 /*Limit driver to four host interfaces*/
/* FULLDRIVER If not set, the audio, non-data functions and some
error recovery functions are eliminated from the
compiled driver. The resulting driver will be smaller,
savings which may be needed on a boot or fixit floppy.
Leaving FULLDRIVER enabled is the recommended setting.
*/
#ifndef BOOTMFS
#define FULLDRIVER
#endif /*BOOTMFS*/
/* RESETONBOOT This setting causes the driver to reset the drive(s)
during probing. This causes any audio playback to be
aborted and the drives will close their trays if they
are open.
Leaving RESETONBOOT enabled is the recommended setting.
*/
#define RESETONBOOT
/* LOCKDRIVE If enabled, when a drive is opened using a minor
number greater than 127, the drive door is locked.
The drive door remains locked until all partitions on
on the drive are closed. The EJECT, ALLOW and PREVENT
ioctls are refused when this locking mechanism is
active. The additional code for this feature is small.
Leaving LOCKDRIVE enabled is the recommended setting.
*/
#define LOCKDRIVE
/* KRYTEN This enables a bug that someone might consider to be a
a feature. If KRYTEN is enabled and you are playing
audio and you issue the resume-play ioctl, the audio
will stutter, playing the same quarter of a second or
so of audio several times before resuming normally.
Resuming from a pause never causes the stutter.
See Edit History for Edit 14.
Leaving KRYTEN disabled is the recommended setting.
*/

/*---------------------------------------------------------------------------
This structure contains the hints for where we should look for the
host adapter. If you want to change where the driver searches or
reduce the places searched to avoid confusing some other device,
either specify explicit addresses in the /boot/device.hints file
(preferred) or change this array.
If the /boot/device.hints config file has multiple ? entries for
the matcd driver, the probe routines will use this table multiple
times and will eliminate each failed entry that probe tries.
WARNING: The number of controller entries for this driver in
/boot/device.hints must be less than or equal to the number of hints
if hints are used.
If you add entries to the table, add them immediately before
the -1 end-of-table marker. The values already present are
the ones used by Creative Labs boards and those of a few
other vendors.
Each additional entry increases the boot time by four seconds,
and can increase the chance of accessing some other device by mistake.
Therefore, the list should be kept to a minimum. Once the
devices have been correctly located, the system should be
configured so that it looks only at the correct location from
that point on.
Be sure to search devices located below 0x3ff BEFORE scanning
higher locations. Some boards don't decode all I/O address lines,
so 0x230 and 0x630 appear identical on the simpler boards.
