I need someone's help with my Boser MPEG card installation.  I'm practically blind about INT, DMA channels, and others.  In the program installation, it asked me to determine the following items:

VIDEO I/O ADDRESS:  option --> 0x1C0 , 0x1E0 , 0x200, 0X220, 0x240, 0x260, 0x280, 0x2A0, 0xC0, 0xE0, 0x300
AUDIO I/O ADDRESS: option --> 0x180, 0x1C0, 0x200, 0x240, 0x280, 0x2C0, 0x300, 0x340, 0x380
AUDIO INTERUPT : option --> 5, 6, 7, 9, 10, 11, 12, 15
DMA CHANNEL:  option --> Channel 6   (only one option)

I have tried to collect my system information from WinProbe, and it revealed that my:
Audio I/O Address are  220-22F  & 330-331 , IRQ:5, DMA:1&5
Video I/O Address are 3B0-3BB, 3C0-3DF  , IRQ:11
IRQ Available:  IRQ9 & IRQ12
DMA Available:  Channel 0, 6, 7

I don't understand why these options are not available by the installation program.   I have tried to modify the WINMPEG.INI file produced by the installation program, it still doesn't work.  The content of WINMPEG.INI is  below:
[WinMPEG]
PATH=C:\BS250
IOBASEV=0x1C0
IOBASEA=0x180
VINT=5
AINT=5
DMA=6
CD_DRIVE=G
CD_SYNC=YES

How should I modify the WINMPEG.INI file to make this work?    
Please help me.
Thank you very much.

try changing VINT=5 to VINT=12 and AINT=5 AINT=12  They are presently conflicting with your sound card

Hello Lvc,

Thanks for your advice, but it still doesn't work. Anyway, what about the address setting for my I/O Video and Audio?  Can I use the default address 0x1C0 for Video and 0x180 for soundcard based on Winprobe information?  My MPEG card manual also stresses out that I have to make sure that the Audio IRQ and Video system settings match on the MPEG card.  With your suggestion, my video CD plays with many long interuptions (2 sec. play and 6 sec. stop), and it finally stops playing at all. I also couldn;t hear any sound coming out from my speaker.   Any suggestion?  Thanks.
