__________________
This file describes the installation of the MMPM/2 MPU-401 device
driver, MPU401.SYS, and related files. This driver uses the new
highres timer driver, TIMER0.SYS.
The MPU-401 driver is actually a dual-function driver, as it supports
both MMPM/2 and the new real-time MIDI subsystem. Therefore, some of
the command-line parameters may have limited or no functionality when
taken in the context of MMPM/2 only.
The MMPM/2 MPU-401 driver has the following functions:
1. Uses the highres timer driver to provide 1-millisecond accuracy, the
highest of any MMPM/2 MIDI driver. A command-line parameter allows
selecting a lower frequency if necessary.
2. Supports up to 8 events independent events, including the new
recurring events.
3. Performs autodetection of MPU-401 hardware. Can support up to 9
MPU-401's (although MMPM/2 only recognizes 1)
4. Automatically uses the 32ms system timer if the highres timer driver
is not found. Timing is reasonably accurate at 32ms.
2.0 COMPATIBILITY
_____________
This graphics accelerator driver is compatible with
OS/2 Warp 3.
3.0 PRELIMINARY STEPS
_________________
If there are any copies of CLOCK01.SYS and CLOCK02.SYS in the
x:\os2 (where x is the boot drive) directory, delete them.
Be sure that CLOCK01.SYS and CLOCK02.SYS are not marked as READONLY.
To remove the READONLY attributes, use the attrib command such as
attrib -r x:\os2\boot\clock0*.sys, where x is the boot drive.
4.0 INSTALLATION
_________________
Unzip the files (or insert the disk), run MINSTALL, and change the directory
to point to where the files are located.
MINSTALL will ask how many MPU-401's are installed. Always answer with 1.
5.0 Optional Command-line Parameters
_________________
The driver attempts to detect the base I/O ports and IRQ's during boot
time. The first valid port that it finds is the one that it uses. In
most cases, command-line parameters will not be required. The driver
currently only supports one MPU-401 when used with MMPM/2.
Autodetect first looks at address 0x330 and then 0x300. If used on a
Microchannel machine, 0x1330 is also checked.
Alternatively, command-line parameters can be used to tell the driver to
skip the autodetect and use given I/O ports and IRQ's instead. Up to
9 MPU-401's, numbered 1 to 9, can be supported this way. MPU-401 #1
is the one that MMPM/2 uses.
Parameters are in the format of:
DEVICE=MPU401.SYS /xn:yyy /xn:yyy ...
Where 'x' is a single capital letter, 'n' is from 1 to 9, and 'yyy' is
the option.
/Pn:yyy Base I/O: Sets the base I/O address for port n, usually 300
or 330 (# is in hex)
/In:yyy IRQ level: Sets the IRQ level for port n. yyy is a decimal
number from 1 to 15. If the base I/O address for a given
port is specified (e.g. /P1:300), but the IRQ is _not_
specified, the driver will attempt to autodetect the IRQ.
Note that an IRQ is not used for MMPM/2 playback anyway.
/N:sss Driver name, an 8-character length string, ending in a $.
Do not specify a port number. Default is "MPU401$".
/R:yyy Resolution of MMPM/2 timing. If the highres timer
(TIMER0.SYS) is installed, this parameter tells the MPU-401
driver what resolution to use (where yyy is the number of
milliseconds) when playing MMPM/2 MIDI streams. Default is
one millisecond.
/V Verbose output during boot. If used, this should be the
first parameter.
6.0 Bugs
_______
The Resource Manager is not used, and therefore autodetect could trample
on other hardware.
There seems to be a bug in MMPM/2's AUDIO_CAPABILITY code, and therefore
this driver doesn't use that feature.
