I am working on a port of the SBBSD unix device driver for the Sound
Blaster.  I have looked at several sample device drivers and I have
almost all the info I need. I have 2 remaining questions:

1) How do you parse the command line from CONFIG.SYS that invoked
   your device driver?

   Say CONFIG.SYS has    DEVICE=D:\A.SYS A B C D

   How do I get the string 'A B C D'? Is it passed as part of the
   initialization request packet?

2) The sample code I have is for pre-2.0 drivers. I understand from
   'The Design of OS/2' that 2.0 drivers are still 16 bit, except for
   the VDD part, which i'm not dealing with. Also, in 2.0 you do NOT
   need to write bimodal code, since the DOS emulation is done in
   protected mode. Do I have this right?

And as a final request, if anyone knows of or has sample code using
DMA I would be very appreciative. I plan on releasing the device driver
into the public domain.

<BEGIN AD>
If you arent familar with the BSD driver for the SB and SB Pro, it
sets up seperate devices for the FM, MIDI and VOICE sections of the
card. Then you can open the VOICE section, for example, and use
standard i/o calls to read and write to the SB. On the SB Pro it
also has a device for the Mixer, so you can control the volume and
other things. I have the source code for TrakBlaster, a .MOD player,
which compiles fine, so all i need now is to finish the device driver.
