My recollection is that under DOS, there were no
"DOS" sound card
drivers - you told your DOS app where the card lived (0x220, for SB
hardware, typically), what its DMA and IRQ were (which varied from
box to box), and the *app* had its own drivers. You typically ran
a setup program for each game that you told if you had an 8-bit
card or a 16-bit card, etc. In this case, Wolf3D is looking for
a real SoundBlaster model and uses the "BLASTER" environment variable
to find its resources. If someone here knows differently, please
speak up.
There are DOS drivers for some cards that add back SB compatibility. The
"VCOS" card in my AT&T Globalyst PC is one of these.
