    Hi,
    I have a Pentium II 400 that I have loaded DOS 6.22. The SoundBlaster ISA card is using IRQ 11 and I would like to change it to IRQ 5. Is that possible and how is that done. If you need more info let me know.

    Thanks.

    You have to go into the autoexec.bat and edit the load line for the sound card, it should read something like SET BLASTER=A220, I5 . Change the I5 would be the IRQ # in this line.

    Thanks for your reply Rockn.

    That's what I thought also that there had to be a line in the autoexec.bat file but when I went into my other machine with DOS 6.22 which the sound card works and opened the autoexec.bat file there was no line about the sound card in it either. What I did notice was that this machine had a file called "CTCM.EXE". So I copied this file into the machine that the sound card wasn't working, ran it, and it worked when I loaded the DOS game. I now have sound!
