Furious googling for this thing suggests that it is either an:
SiS 7012 (which uses THESE drivers)
ICH4 24c5 82801DB/DBL/DBM (ICH4/ICH4-L/ICH4-M) AC'97 Audio Controller (which I cannot find dos drivers for)
3059 VT8233/A/8235/8237 AC97 Audio Controller (Which uses THIS dos driver)
2445 82801BA/BAM AC'97 Audio Controller (which I cannot find dos drivers for)
and maybe a few more. Too busy tonight to dig through the .INF file and compare with the PCIID repository.

VIA AC'97 Sound Blaster drivers for MS-DOS?
The problem I am seeing, is that the manufacturer's "Audio Drivers" package, has so many Vendor IDs and Device IDs that it's a hodgepodge. I cannot uniquely identify what the audio controller will be inside that thing!!
This is not too uncommon though, sadly. Different submodels with different bits and bobs, for whatever was cheaper that quarter. I've seen 'the same model number' with both Intel and AMD CPUs (and thus radically different north and south bridges), and other nonsense. The page says it is intel, but it might have a bios-supplied emulation via "Azalia codec" in the bios. I really cannot tell you.
