;Rev	Date	 Name	Description
;----------------------------------------------------------------------------
;R23	10/22/98 RCH	Fixed compliation error for BIOS part No. - 2A433A19
;R21A	10/12/98 KGN	Fix NMA2 save2ram will fail
;R22	10/02/98 JDN	Added codes for ES1878 suspend/resume
;R21	09/08/98 KGN	Add Neomagic NMA2 sound chip support. as YMF715.
;R20	08/19/98 RAX	Added CS4235  and MPU401 select support.
;R19	06/01/98 JDN	Added codes for YMF715 suspend/resume
;R18	03/20/98 RAY	Move AUDIO_KERNEL definitions to AUDIO.DEF which
;			will be included in COMMON.EQU
;R17	01/08/98 JKY	Suspend ZV before turn on sound chip for ES1879
;R16	11/14/97 DNL	Rename all audio file as audio.aio
;R15	11/13/97 JKY	Suspend ZV before turn on sound chip for CREATIVE 2510
;R14	10/27/97 JDN	Add code for YMF715	
;R13	10/27/97 JKY	When Sound chip = ES1869, Suspend ZV before need active
;			ES1869 , because sound chip drive will inactive sound
;			before APM_16_SUSPEND .
;R12	07/23/97 MIL    Added GPIO 15 to En/Dis OnBoard CMI8330 Audio chip,
;			to call SMC93X.SIO (Program_CMI8330_Audio).
;R11	04/19/97 MIL	added GX86.AIO support.
;R10	04/15/97 JKY	added audio chip zv-suspend save function by audio chip
;R09	04/15/97 JKY	auto detect sound blaster register IO port 224,234,...
;			for suspend to disk save sound
;R08	02/03/97 DNL	Added codes for zero-volts suspend/resume function
;R07	11/27/96 RIC	Add YMF715 support.
;R06	10/17/96 RIC	Add CS423x Enable/Disable Sound Chip function.
;			(Define "Crystal_Item_Cmos_Bit")
;R05	10/14/96 RIC	Add CS4237B support.
;R04	10/08/96 RCH	The WIN/95 driver for YMF701 still have problem and
;			no body use this chip, kill it.
;R03	09/24/96 RIC	Add Crystal CS4236 sound chip support. as YMF711.
;R02A	09/24/96 RIC	Move YMF711 Special Code to YMF711.AIO
;R02	09/06/96 RIC	Add Special_PNP_Audio_Init hook for some Onboard
;			sound chips. Ex : YAHAMA YMF711 PnP sound chip.
;			Because it can design for No EEPROM
;R01	10/27/95 RAX	Add support Creative CT2504 sound chip
;R00	10/20/95 AVN	Buliding Onboard Audio I/O Code.
