Subject
-------
System unable to boot up after installing any of the above-mentioned Sound 
Blaster cards into the system.

Description
-----------
The Gateway 2000 P5-60 pentium system consists of a Mitsumi CDROM drive 
and its own interface card.  Users may encounter the above problem after 
installing the SB16MCD, SBP (Mitsumi) or SB16 (Mitsumi) card into their system 
and connect the Mitsumi drive to any of these cards.  The cause of the problem 
is because the IDE controller in the Gateway 2000 P5-60 system and SB16MCD 
(Mitsumi interface), SBP (Mitsumi) and SB16 (Mitsumi) are using the same DMA 
channel - 7.  Therefore, the hard drive(s) could not be initialised properly when 
booting up.

Solution/Action
---------------
This problem can be solved by changing the DMA channel on the SB16MCD, 
SBP (Mitsumi) and SB16 (Mitsumi) card from 7 to 6 so that it will not crash with 
the IDE controller.

Please note that any other interface cards that use DMA channel 7 are also 
subjected to crash with the SB16MCD (Mitsumi), SBP Mitsumi and SB16 
Mitsumi cards.  The symptom(s) may vary with different systems.
