Hi,

I have an older SB16 sound card (Model CT2230) equipped with a wavetable
(Yamaha DB-50XG). Unfortunately the kernel  (NetBSD-1.4) does not
recognize the MPU401 port. 


here is the relevant part.. 
# ISA audio devices
sb0     at isa? port 0x220 irq 5 drq 1 drq2 5   # SoundBlaster

# OPL[23] FM syntheziers
opl*    at sb?

# Audio support
audio*  at sb?

# MIDI support
#midi*   at pcppi?               # MIDI interface to the PC speaker
midi*   at sb?                  # SB MPU401 port
midi*   at opl?                 # OPL FM synth

# The spkr driver provides a simple tone interface to the built in
speaker.
#spkr0  at pcppi?               # PC speaker



dmesg output:
-------------
sb0 at isa0 port 0x220-0x237 irq 5 drq 1 drq2 5: dsp v4.13
audio0 at sb0: full duplex
opl0 at sb0: model OPL3
midi0 at opl0: <SB Yamaha OPL3>
pckbc0 at isa0 port 0x60-0x64
pckbd0 at pckbc0 (kbd slot)
pckbc0: using irq 1 for kbd slot
wskbd0 at pckbd0
pcppi0 at isa0 port 0x61
sysbeep0 at pcppi0


Did I miss something ?
