OK I have played with this for a couple of days and I need some help with this. I have a 80GB hard drive and I am using one of its Partitions for DOS 6.22 and the rest for Windows XP Home edition, all works fine in DOS except for the sound. My Mobo has an intergrated VIA AC97 soundcard, In my BIOS it has an option for Soundblaster support so I turned that on, and all my games detected it OK but none of them had sound and With SB Support turned on in the BIOS WinXP Hangs up while loading so I browsed a lot of past posts here(and other places) and found the AC97 to be a problem with legacy support (Although it claims to do it perfectly in the Mobo instruction book) so I dug into my box of parts and found a Soundblaster CT3600 ISA Soundcard with an IDE controller on the end of it and put that in my puter and disabled the onboard sound. Then I went over to creativelabs.com and snagged the driver for it. Upon installing it told me I needed a Plug n Play manager for DOS to install this card so I went back to creative and got that as well. But it installed my card with an IRQ of 10, wich is unusally high for DOS and my games didnt have 10 for an option or if they auto-detected it thet said it was conflicting with something else. So I went back to the BIOS and Reserved IRQ 5 and DMA 1 for ISA/Legacy devices so they would be free to use on the sound card, and I ran the Plug N PLay Manager adn changed the settings in there and my autoexec.bat. But my games still dont detect the sound Blaster Card as being there. And one game exits right after starting saying my sound settins are incorrect although that are set exactly to what they are in the autoexec.bat
the card works fine is WIN XP and I can use the CD Player utility to play CD's in DOS but my games refuse to recognise the card as being there. I dont know if it will help but here are my system files as well:

Config.sys
DEVICE=C:\CTCM\CTCM.EXE
DEVICE=C:\DOS\HIMEM.SYS
DEVICE=C:\DOS\EMM386.EXE RAM
DOS=HIGH,UMB

SET CTCM=C:\CTCM

Thanks in advance for any help you can give sorry that was so long just trying to give you all the info:)

If a modem is attached to the computer, it takes the same resources as the sound card and you loose the sound blaster emulations. You still retain some emulations like Windows sound sytem for example.Check the modem resources particularly the IRQ.Most dos games work well with sound blaster Pro and A220 I5 D1.You have to choose between sound or modem.Older PC's based on ISA bus (up to Pentium I with no PCI slots)had much less problems with dos configuration. Good luck.

Ok I checked it out and I do have an analog modem installed, Creative Modem Blaster, SO I removed it since I no longer use it I use an external cable modem now, but havnt tried to see if it works, will let you know!

Thanks

OK I did that and still no luck, so under further investigation I found that My Vid Card and USB Controllers were also using the same resources. SO I changed all that so that nothig was using them except my sound card but still no luck. Another thing i noticed upon running MSD is that DOS dosent seem to recognise my sound card at all, even though it shows to load successfully and i get no errors, MSD dosent detect it as being there, however if i turn on my AC97 with SB Emulation it DOES detect a Sound Blaster card and my games work with the settings, but no sound :(
an ideas??

Thanks in advance
