;			successfully while the PS/2 mouse is not plugging,
;			the card will set to disable automatically while
;			without PS/2 mouse.PS/2 mouse plugging flag isn't
;			config_table+5 ,so change to SYSTEM1_BYTE(bit 2).
;			Config_Table+5 is EBDA flag. See atorgs.asm
;R13A	12/24/97 STV	Release Added LAN card Support by cbrom /lan
;			& Fixed LAN card boot ENABLE/DISABLE
;R18	12/24/97 RCH	Fixed error coding that cause system RAM 40:BA become
;	 	        always 0FFH and system always boot from LAN even LAN
;		        is not first boot priority.
;R17	12/23/97 RAY	Problem:
;
;			  Some onboard VGA will hang up randomly if the
;			  onboard VGA ROM is not plugged and at the same
;			  time the ROM image is added to the BIOS using
;			  CBROM.EXE.
;
;			  This occurs in Quantas's LX M/B with ATI-RAGE
;
;			Solution:
;
;			   We should disable the ROM completely(write 0 to
;			   register location 30h) when we do not find any
;			   valid ROM images both from high address & from
;			   C000:0000h
;
;R16	12/23/97 RAY	Add [BP] for current class code
;R15	12/23/97 RCH	Fixed S3/868 hang up while working on AGP platform
;			with 16Mb Aperture size selected. It is caused by
;			this VGA requesting 32Mb memory space but actually
;			decode 64Mb space.
;R14	12/23/97 RAY	Fix Adaptec's ROM which support all 78x0 devices
;			cannot be invoked by the new CBROM algorithm
;R13	12/18/97 STV	Added LAN card Support by cbrom /lan
;R12	12/16/97 RAY	To record the assigned PCI IRQs in F000 shadow RAM
;			for the IRQ routing table(both INT 1Ah & MS IRQ
;			Routing table) to reference.
;			This is to to fix the ICU hang up problem
;R11	12/16/97 RAY	Some PCI device report a value of FFFFFFFFh at 30h
;			This version of BIOS will treat it as "ROM required"
;R10	12/16/97 RCH	Fixed system hang up while initial PCI/VGA ROM if
;			Rendition Verite V2200 is installed and Cyrix M1 or
;			M2 is used with VIA/VPX chipset.
;R09	12/05/97 PAL	Added Trend_AntiVirus Support by cbrom /vrs
;R08	12/05/97 TNY	Set IRQ9 to be the last of IRQ_Order table.
;			To fix some PCI card behaving abnormally in Win95 if
;			IRQ9 assigned.
;R07	12/01/97 RAY	Some VGA ROM images don't includes the PCI Vendor ID
;			& Device ID. Thus when we seek for VGA image, we have
;			a default image that points to the first image that
;			added with "CBROM /VGA"
;
;R02B	11/17/97 RAY	Fix "CBROM /PCI" does not work with 1M BIOS
;R06	11/15/97 RAY	Symtom:
;
;			  Some PCI devices do not decode address A8. When we
;			  assign I/O space to these kind of devices at address
;			  using A8, they will fail to decode the correct
;			  address.
;
;			Solution:
;
;			  No matter it is in bus 0 or not, we assign I/O
;			  space with 1K alignment.
;
;R05	11/14/97 RAY	Add Open_IDE_2nd_Channel
;
;R04	11/14/97 RAY	Move Routine: Reserve_Irq_For_PciBootDev to XGROUP
;
;R03	11/14/97 RAY	Modify the algorithm for searching combined NCR SCSI
;			ROM
;
;R02A	11/14/97 RAY	Problem fixed:
;			When apply both /NCR & /AHA to old CBROM.EXE, NCR SCSI
;			ROM is not loaded
;
;R02	11/13/97 RAY	Add new CBROM.EXE support
;		 STEVEN	Since this function is very code is complicated,
;			I clear all the Rxx for easy debugging. From now on,
;			any changes to this file should add Rxx.
