Windows 95 AC97 drivers and inf mods

Hello, this is one of my first topics in MSFN, one of the things i've considered posting is about Windows 95 onboard AC97 audio drivers and inf mods which were needed in some drivers (had to do for some systems). Also to recopilate them as well

The inf modded versions are made due to some AC97 driver packages for Windows 95 (notably Realtek and C-Media), deliberated cut support for many chipset AC97 controllers in the Windows 95 version, but supported in the Windows 98/ME/2000/XP versions even if the driver version is the same as the later one, the mod puts the HW support in the Windows 95 version on par with the Windows 98/ME/2000/XP version

 

Warning: Keep in mind some of the chipsets like Intel ICH6/7, nForce4 variants, SiS 965/966 and ATI IXP4x0/SB4x0/600 support both AC97 and HDA codecs, so make sure your board uses an AC97 codec for audio. High Definition Audio (HDA) codecs are NOT supported

 

Advance Logic/Realtek AC97:

Supported codecs: ALC100, ALC100P, ALC101, ALC200, ALC201, ALC201A, ALC202, ALC202A, ALC203, ALC650, ALC653, ALC655, ALC658, ALC850
Supported chipset/southbridges: Intel ICH0/1/2/3/4/5/6/7, VIA VT82C686A/B, VIA VT8231/VT8233/VT8235/VT8237, SiS 630/730, SiS 961/962/962/964/965/966, nVidia nForce 1/2/3/4, ATI IXP/SB up to SB600

Tested working on Asrock Conroe865PE (i865PE+ICH5, Realtek ALC850)

v4.06 Win95 inf edited to add Intel ICH5/6/7 AC97, ATI AC97, AMD AC97, ALi/ULi AC97 and nForce 1/2/3/4 AC97 ids, original infs only supported Intel ICH up to ICH4, VIA and SiS

C-Media AC97:

Supported codecs: CMI9738?, CMI9739?, CMI9761, CMI9780

Supported chipset/southbridges: Intel ICH0/1/2/3/4/5/6/7, VIA VT82C686A/B, VIA VT8231/VT8233/VT8235/VT8237, SiS 630/730, SiS 961/962/962/964/965/966, nVidia nForce 1/2/3/4, ATI IXP/SB up to SB600

Used infs from AsRock's site, inf edited to add Intel ICH4/5/6/7 AC97, ATI AC97, AMD AC97, VIA AC97, SiS AC97, ALi/ULi AC97 and nForce 1/2/3/4 AC97 ids, original infs only supported older ICH, found in boards like Asrock P4I65G and 775I65G

Needs testing, will probably test it against my Asrock P4I65G/775I65G, Gigabyte GA-8S648FX-RZ and DFI K8T800-Pro-Alf

VIA AC97:

VIA Vinyl 7.00b claims to support Windows 95, but can't find anything related to it on the folder, may check earlier releases later. TO-DO

 

ADI SoundMAX AC97: 

Need to find an apropiate Win95 driver, TO-DO

 

Sigmatel AC97:

Can't find anything related to Windows 95, TO-DO

Supported codecs: STAC9700/STAC975X

 

SiS AC97:

SiS 7018 codec doesn't support Windows 95 and seems like SiS doesn't provide Windows 95 drivers, can't verfy it right now since i don't have a SiS 7018 equiped board

SiS 7012 is supported and SiS provide drivers, although you are better using Realtek or other vendor driver if your SiS chipset board is paried with a Realtek/C-Media/SoundMAX/other vendor codec

 

If someone has an input about this, feel free to reply to this thread or tell me
