Sounds like he has the Intel Atlantis (Advanced/AS), which has the CS4232C
soundcard-on-a-chip, and an ATI mach64 video card (video card is optional)
built into the motherboard. From Intel's Atlantis FAQ
(http://developer.intel.com/design/motherbd/as/as_inst.HTM):
-----
How can I disable the Crystal audio component on the Advanced/AS?
For non-Plug and Play operating systems (DOS, Windows, WFW, etc.) you need
to use the ISA Configuration Utility (ICU) to disable the Advanced/AS
on-board Crystal Audio subsystem. Important note: The DOS/Windows ICU
should not be used with Windows 95. 

Follow these steps with non-Plug and Play operating systems: 
<snipped out>
To disable the on-board sound using the Windows 95 device manager: 
<snipped out>
It basically says to uncheck the box marked "Original Configuration".

Finally, using a text editor, add REM in front of C:\win95\cs4232c.exe /w
/x in the CONFIG.SYS file. 

The above procedure can be used for disabling the Crystal Audio component
using version 1.24 of the Windows 95 Crystal audio drivers. The above
procedure also can be used to disable the Crystal Audio component for
drivers previous to version 1.24. The driver names in the Device Manager
for previous versions are: 
•Crystal CS4232PNP Audio Hardware •Gameport Joystick •MPU-401 Compatible

Obviously, not very friendly to non-Micro$oft systems.
