    Question
    There is a problem with the audio driver (CD1.1s and the updated one from thewebsite) on K7S5A PCB 3.1B (CMI9738 chip) when using windows 98SE. BIOS we have tested are from 1/12/02 to the most updated from the web.System will freeze at "do you want to restart computer screen" at the end of CMedia driver installation when you do driver auto installation. At this time, mouse could still move around but could not do anything else. System will also fail to re-enter windows 98 after restart from windows 98 SE if you do a manually driver installation from device manger. The following message will appear in DOS mode. "While initializing device CONFIGMG: Windows protection error. You need to restart your computer." 


    Answer
    New 9738 audio driver can fix it.


    Question
    No post with 133/133 setting and DDR266 on K7S5A PCB 3.X. Basically, it seems to happen on some AMD XP1800+ CPU. 


    Answer
    Update BIOS V02/10/01 to the latest versionfor patch on this issue .


    Question
    We had problem getting the front & Back audio to work in our chassis.If we had front panel connect to the front audio connector of K7S5a, the back audio will not work.The only way to get the back audio working is to remove front audio.Please advice if there is a solution. 


    Answer
    Basically, the H/W design does not allow audio output to both front side and back side at the same time. If your customers still want to use the audio in both sides for special reason, they have to short both PIN 5-6 and PIN 9-10. This is only for special service and it will not be changed for mass production.


    Question
    Does K7S5A support AMD Sempron CPU? 


    Answer
