Hi dear all,
I have dual boot. C:> win2k and d:> winxp
I have gigabyte motherboard with inbuilt
audio controler. In windows Xp sound works well and it shows audio controller as
intel(r) 82810 BA/BAM AC’97 AUDIO CONTROLLER.
well xp installed its driver by itself. but i dont get it in windows 2000. I installed required chipset provided but its not getting. in readme.txt of chipset it says it will identify above devide but i can not get it.. i just formatted the machine just before formating it was working in win 2k but after that i lost it. how to install audio driver for my inbuilt sound . can someone send me driver for it. it doesnt take sigma ,creative ac’97 drivers also. please help.
regards,
