no sound in old dos game

[bobby46]

I'm trying to run an old DOS game (Dawn Patrol) on my win98SE driven PC. I made a game startup floppy, and successfully have the game running except that there is no sound. My motherboard employs the ac97 audio chip. I seem to recall from the distant past (and an older PC) there was a "device=" line in the boot floppy config.sys file that identified a sound driver file. Is there such a file associated with the standard via realtek ac97 onboard audio chip?
Do I need to buy a separate sound card to get DOS sound? My floppy autoexec file already includes the necessary "set blaster=A220 D1 I5 T3" line. HELP!

You need to find a DOS driver for that audio chip or install a sound card that offers them, older Creative cards will have proper DOS emulation in Win98. All the "set blaster" line is doing is defining I/O address, IRQ, and DMA channel. A driver has to be loaded using a device or devicehigh line in config.sys.

Thanks GLC, confirming my suspicion I need a dos driver. My motherboard website (MSI) wasn't any help. The ac-97 onboard chip is found on so many motherboard brands, I was hoping someone had already been through this to advise if there is a dos driver available.
BTW, I downloaded the latest via-sound win98 driver, and the readme had no mention of dos functionality.

I finally got a reply from the onboard chip manufacturer:

The AC'97 does not support DOS.

Also many, many PCI sound cards do not support DOS.
One that does is the old Avance ALS4000. Their site has a download called DOS.ZIP which alters your floppy's autoexec for you. I am successfully using this card, now. Hope this info helps someone else...
