3. WINDOWS 3.x/DOS DRIVER INSTALLATION PROCESS
!!! Note: For Windows users, please exit from Windows and run
the installation from DOS. !!!
The hard disk installation program, INSTALL.EXE, will copy
the necessary files from OPTi Installation disk into your hard
disk. Follow the following procedure to install the software:
(Assuming you are using floppy drive A, and you wish to install
to hard disk drive C)
1. Place the disk labeled " Windows 3.x/DOS Drivers " in
Drive A.
2. Type a: and press ENTER to change to Drive A.
3. Type install and press ENTER to begin the installation.
INSTALL.EXE will do the followings for you:
a.) Create the directory \OPTI in your hard disk drive.
b.) Prompt you for CD-ROM and sound card options so that after
you have finished the installation and have rebooted your
machine, you will be ready to use the sound card.
c.) Copy the files in your floppy disk to the \OPTI directory
and Windows directory respectively.
d.) Update your CONFIG.SYS, AUTOEXEC.BAT and SYSTEM.INI files
In CONFIG.SYS
If you use a CD-ROM with the sound card:
DEVICE=C:\OPTI\CDSETUP.SYS /T:I /P:170 /I:15
If you don't use a CD-ROM with the sound card:
DEVICE=C:\OPTI\CDSETUP.SYS /T:X
In AUTOEXEC.BAT:
PATH=C:\OPTI (appended)
SET SOUND16=C:\OPTI
C:\OPTI\SNDINIT /B
SET BLASTER=A220 I5 D1 T4
^
|
+------- IO: 0x220, IRQ: 5, DMA: 1
In SYSTEM.INI:
- [drivers]
WAVE=SND924.DRV
AUX=SND924.DRV
MIDI=SND924.DRV
MIXER=SND924.DRV
[386Enh]
;OPTi COMM interface. Please do not delete/modify
COMxBase=modem IO Port
COMxIrq=modem IRQ
DEVICE=VSND924D.386
[snd16.drv]
SingleModeDMA=YES
CodecType=AD1848
* SND924.DRV is the Base driver comprising WAVE, MIDI,
MIXER and AUXILIARY audio services.
* The program only add/update the lines related to modem
when the sound card supports modem.
* VSND924D.386 is the Virtual Device driver for Windows
Enhanced Mode.
* x in the COMxIrq, COMxBase is the COMM number (0-4,
0 means that modem is disabled).
4. WINDOWS 95/DOS DRIVERS PACKAGE INSTALLATION PROCESS
During the installation of 82C924/925 Windows 95 driver,
the installation program will insert a line in AUTOEXEC.BAT to
invoke the SND4DOS program to install the 924/925 DOS driver.
After installed the Windows 95 driver, the Windows 95 asks for
a reboot to make the new hardware (in this case, sound device)
to work properly. After reboot, the SND4DOS will be invoked and
bring up the DOS driver installation program (install.com on the
installation disk ) to install the DOS driver and remove the line
SND4DOS inserted in AUTOEXEC.BAT.
Please follow the following procedure to install the software:
1. Follow the installation guideline provided with 924/925
Windows 95 driver to install the Windows 95 driver.
2. During the first reboot after installed the 924/925 Windows
95 driver, the program SND4DOS will take over. Just follow
the instrution of SND4DOS to bring OPTi DOS Installer to
setup the Sound Card for your Windows 95 real DOS environment.
!! If you decide not to install at current time, you always
have a chance to re-setup your sound card support for DOS
later. Just type C:\SND4DOS at your Real Mode DOS Prompt.
3. DOS Installer actually is the same one as DOS/Win3x.
The differences are
a. it won't install Win3x Drivers and applications.
b. it inserts a line into DOSSTART.BAT in Windows 95
Home Directory.
DOS Installer will modify Windows 95 system files:
In CONFIG.SYS
If you use a CD-ROM with the sound card:
DEVICE=C:\OPTI\CDSETUP.SYS /T:I /P:170 /I:15
If you don't use a CD-ROM with the sound card:
DEVICE=C:\OPTI\CDSETUP.SYS /T:X
In AUTOEXEC.BAT:
PATH=C:\OPTI (appended)
SET SOUND16=C:\OPTI
C:\OPTI\SNDINIT /B
SET BLASTER=A220 I5 D1 T4
^
|
+------ IO Port: 0x220, IRQ: 5, DMA: 1
In DOSSTART.BAT:
C:\OPTI\SNDINIT /B
5. SNDINIT.EXE COMMAND OPTIONS
You can issue the following command to get the command
line options about sndinit.exe:
- SNDINIT /?
The command options you can use with the SNDINIT are:
/b - Setup and initialize the sound card. The
program doesn't bring up the graphical
user interface to let you select the
sound card settings. This is the option
normally used.
/b /m - Setup sound card for playing games from
MindScape.
/v - Activate Volume Control program to let
you adjust the volume settings.
/s - Let the user to select resources.
When the system doesn't use Intel's CM,
The program uses the resources the PnP
BIOS assigns to the sound card if the
system has a PnP BIOS. But if you want
to overrule the PnP BIOS, use this option
and the program will allow you to choose
the resources you want to use for the
sound card. Once you use this option,
your machine will use the settings you
chosed ever after.
/u - Unlock the resources user selected. This
is the reverse option of /S. Once you
use this option, you will lose all the
settings you chosed by /S, and the program
will use resources the PnP BIOS assigned.
/r - Use this option only in the case that
after the installation of the sound card,
the PnP BIOS disables the secondary IDE
interface on the motherboard, and you must
connect the CD-ROM drive to the IDE interface
on the sound card in order to make CD-ROM
drive work. This option trys to enable the
IDE interface on the sound card even when the
secondary IDE interface exists in the system.
None - Activate configuration program. Normally
you shall use SNDINIT without any option
to change the settings of your sound card,
like when you change your CD-ROM drive, or
you like to disable/enable the game port
interface on your sound card, etc..
6. CD-ROM Interface Setup
The CD-ROM Setup Device Driver is CDSETUP.SYS. This driver sets
up the CD-ROM interface on the 82C924/925 sound card. Each time
you changed or added a CD-ROM to your sound card, the line
"DEVICE=CDSETUP.SYS..." will be added to the first line
of your CONFIG.SYS file before the CD-ROM device driver line.
CDSETUP.SYS is defined as follows:
DEVICE=[drive:]\[directory]\CDSETUP.SYS /T:[/I/X]
[drive] = drive where you have the driver installed
[directory] = directory where the driver is located
[/I/X] = type of CD-ROM drive
I stands for IDE drive
X stands for no CD-ROM
For example, the following line sets up the interface for a
IDE CD-ROM:
DEVICE=C:\OPTI\CDSETUP.SYS /T:I
Notes for 82C925:
----------------
Normally, the IDE CD-ROM uses IO ports 376h, 170h and IRQ
15. But when the system has a secondary IDE interface on the
motherboard, the PnP BIOS may assign resources other than
376h, 170h and IRQ 15 to the IDE interface on the 925 sound
card. It is recommanded that the users always connect
their CD-ROM drive to the on-board secondary IDE interface
when it exists on the system. This is because most of the
BIOS or PnP configuration manager favor the secondary IDE
interface and allocate the default resources (376, 170, 15)
to it, if the user choose to use the IDE interface on the
sound card, the DOS IDE CD-ROM driver may not work if the
sound card doesn't get default resources.
But some BIOS may disable the secondary IDE interface on
the motherboard and give the default resources to the IDE
interface on the sound card. In this case, the user must
install the CD-ROM drive to the IDE interface on the sound
card to make the CD-ROM works.
However, if you choose to install the IDE CD-ROM to the 925
sound card IDE interface, even though the CD-ROM drive
doesn't work in DOS, it may work in Windows 95, if you are
lucky, I mean, if you got a good BIOS in your system. You
can get two IDE CD-ROMs on your computer.
7) Run DOS games in Windows 3.x
a) Sometimes, the Setup of the PIF file of a DOS game is crucial.
To make a game work effectively under Windows, you probably
have to try a few alternative options through PIF editor.
b) Not all the DOS games can run in Windows' DOS BOX. Some of
them just don't run because of system restrictions.
