Do you think it would be possible to allow complete direct access to
the Sound Blaster card in Dosemu, so that I could set the mixer from
Dosemu?
Yes, this must be possible.
You won't hear any sound in
most cases, but the mixer will
work, and so will the OPL3. Just
don't forget to tell your DOS
programs that it is the Adlib,
not SB, or the detection will fail.
Actually, even the sound will
work in some very old games like
"Another World", which do not use
the DMA.
I've been trying to get this to work, but I haven't succeded so far.
I've added an extra $_ports line for the 0x220 range of ports and I'm
passing IRQ 5. (At boot-up I see this one is assigned to the card.) It
seems that the card still needs some extra initialization before it will
work though. I've got the DOS driver working on a Dos partition, but
loading Linux after that with linld (loadlin doesn't seems to work with
my kernel), the sound is gone again in Dosemu. The mixer I'm using isn't
able to detect the card anymore.
I don't know if it would be possible to do the initialization from
within Dosemu, but I think that would require to much direct hardware
access.
