;Rev	Date	 Name	Description
;----------------------------------------------------------------------------
;R26	02/10/99 GAR	Added LPC47U33X
;R25	02/09/99 GAR	Fix compile bug.
;R24	02/01/99 GAR	Add No_Use_Parallel_Port
;R23	02/01/99 GAR	Add IRQ10, IRQ11 for auto
;R22	11/16/98 GAR	Report Secondary IO nodes
;R08B	09/16/98 GAR	Fix error. When define "Use_16bit_Decode" and
;			"NO_IR_selectable", the option of "Auto" of COM will
;			not release IRQ3 and IRQ4.
;	
;R08A	08/19/97 TNY	Fix coding error.(AUTO COM port is error if "NO_IR_selectable"
;			defined.
;R21	08/18/98 GAR	Add "Lpt_Has_Auto"
;R20B	08/04/98 GAR	Fixed bug. If we don't define NO_USE_COM2
;R20A 	08/03/98 KVN	Fixed coding mistake by R20 that will cause system
;			hang on any where of POST.Because it will destroy BIOS
;			code in Auto_Cfg_SuperIO subroutine.
;R20 	07/31/98 DRS	Fixed compiler bug. If we use SMC37M60X definition
;R19	07/17/98 RCH	Added a switch to support only one COM port
;R18B	07/08/98 LAW	fix auto setting 3e8h error
;R18A	06/22/98 LAW	For product announcement for Change Default Value of
;			IRQ3/4 and auto ALgorithm
;R18	05/26/98 LAW	add "AUTO_CHECK_IRQ3_IRQ4" for when UART1/2 selected
;			AUTO
;R17	12/24/97 LAW	added "Secondary_IO_Use" for Program Secondary IO after
;			check Com port conflict 
;R16	11/26/97 LAW	added ITE8661_WITH_UMC8670 "NO_AUTO_COM_LPT"
;R15	10/13/97 LAW	remove Init_PS2Mouse_Proc to E0post.asm after MS_Install
;R14	09/17/97 PAL	Added SMC37C669_ITE8661 "NO_AUTO_COM_LPT"
;R13	09/15/97 LAW	added PS2Mouse Init for Use Mouse button power on
;R12	09/08/97 LAW	Use MASM6.11 Compiler
;R11	09/04/97 LAW	Added 513x5113 "NO_AUTO_COM_LPT"
;			and added "Set_Not_Available_IRQ_For_4COM_NO_PNP_NODE"
;R10	09/02/97 LAW	fixed serial port auto no set IRQ3 /4 not available
;R09	08/19/97 LAW	added Public E_WRITE_ITEM_VALUE for Winbond 83977TF
;			"Password_ON_NOW_SUPPORT" 
;R08	06/13/97 LAW	modfify code for define "NO_IR_selectable" and "Use_16bit_Decode"
;			COMPILE error
;R07	04/17/97 LAW	Added W9775119 "NO_AUTO_COM_LPT"
;R06	04/17/97 LAW	Added S93x8669 "NO_AUTO_COM_LPT"
;R05	03/12/97 LAW	Added I8680663 "NO_AUTO_COM_LPT"
;R04	12/04/96 LAW	Added some superio.sio no support AUTO_COM_LPT ,so must
;			define "NO_AUTO_COM_LPT"
;R03	12/03/96 RAY	should preserve DS before we call Prg_Super_IO_Chip
;R02	10/04/96 RAY	Clear the "no. of LPT", "no. of COM" & "Game port"
;			flag after auto configuring the onboard COM ports in
;			the 40:0 BIOS area to maintain compatibility.
;			If this is not done, the FINDIRQ.COM utility will
;			show up with COM1 & COM3 using the same IRQ line.
;R01	08/13/96 RAY	Temporarily remove the Lpt port auto-config
;			functionality because it will cause DMA resource
;			conflict when ISA PnP device is plugged & Lpt port
;			is set to ECP mode.
