Dear Friends

I have an old Cyrix Media GX Mother Board with CyrixInstead 266 Mhx MMX Processor.

This mother board has built-in Audio, Video, Multi Media.

Audio Port on the mother board has the following information :

Analog Devices
AD1819AJST SOUND PORT
BTB13757A 0.6
9837 UK

BIOS Informnation as follows
Program : Unicore BIOS Wizard Version 1.9
Program : Unicore Chip Detect v0.72 2000.03.10
BIOS Date : 10/13/98
BIOS Type : Award Modular BIOS v4.51PG
BIOS ID : 10/13/1998-GXm-Cx5530-2A434001C-00
BIOS Eval : GXm+ 02810

CPU INFORMATION AS FOLLOWS

VENDOR : CyrixInstead
Instr. Family : 80586
Frequency : 266 MhZ
Stepping : 0h
Type : M2
Model : 47h-Gx86(tm)/P150

I have searched and loaded most of the nearest drivers for sound port.
But whenever a bit of sound is playing the system is hanging.
(1) Cyrix Media GX MMX Drivers from Driverguide.com
(2) AD1819 drivers from Driverguide.com
(3) GX drivers from Driverguide.com

None of the above worked for me. My problem of Hangind and giving error messages with a word "VMM". Finally I have to press reset
button to run the system for other than sound works.

Is it Sound Port problem ? OR
Is it Drivers problem ? OR
Is it any Hardware Problem ?

Pl. let me know the reason for my problem ? I shall be verymuch
thankful to the one.

Thanking you

With Regards
