Several days ago (I think May 2), Mike Newell asked:

I wrongly asked him to check if the card still work by testing it with
the DOS drivers, but it wasn't until he said he broke down and bought the
Gus PnP, did the 2.2.x part of his message clicked in my ever shinking brain.

For those of you that are using the guspnp6.tar.gz code with a GUS original
or MAX, you may be like me and need to add the following line to
sys/i386/isa/sound/gus_wave.c:

*** gus_wave.c.orig     Tue Nov  5 12:56:04 1996
--- gus_wave.c  Thu May  8 12:53:06 1997
***************
*** 4830,4835 ****
--- 4830,4836 ----
        if (gus_pnp_found[i] != 0 && gus_pnp_found[i] == hw_config->io_base) 
          gus_pnp_seen = 1;
    }
+ /* XXX */ gus_pnp_seen = 0; /* XXX */
    gus_irq = irq;
    gus_dma = dma;
    gus_dma2 = dma2;

after making this change, showaudio, vat will work with an older GUS. NOTE
this breaks GUS PnP support. I am only mentioning this for those of us that
have the old cards.

I apologize to Mike for my earlier mistake, I think you are better off with
the GUS PnP.
