[DRIVERS] SECTION
The [drivers] section lists installable device drivers for
Windows with Multimedia Extensions. These drivers do not
include Media Control Interface (MCI) device drivers, which
are listed in the [mci] section of the file.
Entries in this section have the following format:
device_type=driver_name [parameters]
The device_type is the type of device, and the driver_name
is the filename for the device driver installed for that
device type. Parameters that are specific to a device driver
may follow the driver_name. Alternatively, these parameters
may be given in a section with the same name as the device
driver:
[driver_name]
keyname=value

SECTIONS FOR WINDOWS WITH MULTIMEDIA DEVICE DRIVERS
---------------------------------------------------
As noted earlier in this file, for any device driver described
in the [drivers] section of SYSTEM.INI, parameters may
be defined in a section with that device-driver name.
The following device-specific sections define parameters
for the default device drivers provided in Windows with
Multimedia Extensions:
[ibmjoy.drv]
[sndblst.drv]
The following sections describe the entries that may
appear in these sections. (Additional sections may appear for
other audio, video, or peripheral devices installed on the
system.)
------------------------------------------------------------
[ibmjoy.drv]
axes=<2-or-3>
timeout=<hex-number>
Defaults: axes=2
timeout=0x3000
Purpose: The axes option specifies whether the joystick is
two-dimensional (2) or three-dimensional (3). The
timeout option is a hexadecimal value specifying
how many times the joystick driver is polled before
the system determines that a joystick is not installed
on the system.
To change: Use Notepad to edit the SYSTEM.INI file.
------------------------------------------------------------
[sndblst.drv]
port=<hex-humber>
interrupt=<number>
DisableWarning=<Boolean>
Defaults: none
Purpose: The port option specifies the port number for
the SoundBlaster audio card. This is the port
where the jumper on the card is set. The interrupt
option specifies which interrupt the SoundBlaster
uses. The DisableWarning option, if enabled, displays
a warning message if an MS-DOS application running
from the Windows DOS Prompt tries to access the
SoundBlaster port given in the port option or the
interrupt given in the interrupt option. This
option is enabled by default.
