I am trying to use the Sound Blaster 16 PCI under DOS, but I'm having issues. I load HIMEM.SYS and EMM386.exe in my CONFIG.SYS, and then I enter SET BLASTER=A220 I5 D1 T7 P330 and then run SBLOAD.EXE, and SBINIT.exe. When I run SBTEST.EXE, I hear a loud, repetitive screech until the test ends, but when it tries to play MIDI music, I can hear a piano over the noise. What is happening? Also, I assume those settings are correct for the card, but I don't know how to detect the correct settings for the BLASTER environment variable.

What's the CT model # of the card?

TRY: CONFIG.SYS bDEVICE=C:\DOS\HIMEM.SYS DEVICE=C:\DOS\EMM386.exe NOEMS NOVCPI DOS=HIGH, UMB AUTOEXEC.BAT SET BLASTER=A220 I5 D1 H7 P330 T6 SET SBPCI=C:\DOSDRV C:\DOSDRV\SBLOAD C:\DOSDRV\SBINIT.COM C:\DOS\SMARTDRV.exe

The drivers/readme I am referring to came from the sbpci.zip http://www.mameworld.net/dosmame/other.php#downloads Though one needs to ignore the auto install and configure/install manually.

Actually, I got it to work by changing that BLASTER line to SET BLASTER=A220 I5 D1 T6 H7 P330. I had it wrong before. I was using files from a zipfile called SBPCI.zip. If you're still curious, the model was CT4750, I think.
