;R10	04/07/99 RAY	Add "COMPILE_FOR_PCI21TBL_ASM EQU 1" to tell COMMON.EQU
;			to do special compiling for this file.
;R09	10/15/98 RAY	Support up to 9 PCI slots.
;R08	09/10/98 LAW	Fixed USB Device Enable WIndows 98 IRQ Steering cann't
;			Enable
;R05A	09/03/98 RAY	The USB routing must be placed at the end of the
;			PCI routing table. R05 put AGP at the end!
;R07	06/30/98 RCH	Added PCI IRQ routing dynamic change by GPI state
;			for onboard multi-function AHA7895 SCSI.
;R06	06/23/98 RCH	Added six and seven PCI slots IRQ routing table support
;R05	06/23/98 RCH	Added AGP PCI/IRQ routing table support
;R04	04/20/98 KGN	Patch define CARDBUS_USE_LAGECY, routing table report
;			wrong device number
;R03	12/16/97 RAY	Report the assigned PCI IRQs instead of a fix value
;			in the Field of "Exclusive IRQs"
;			This is to to fix the ICU hang up problem
;R02	08/05/97 RAY	Rewrite this file to pass the IRQ-Routing test running
;			in Memphis. Due to this is a great change, I also kill
;			all the ;Rxx because the BIOS didn't pass the Memphis
;			test since Aug-1-97. Please forget R00 & R01 !
;
;			To pass the test, we have to do the followings:
;
;			1. The MS '$PIR' table must be supported
;
;			2. The MS '$PIR' must match the table returned by
;			   API call in PCI1A.ASM & PCI32.ASM. So we created
;			   this file for both the MS $PIR table and the
;			   PCI1A(PCI32) to reference. 
;
;			   There is a tricky routine in PCI32.ASM: Get_Next_IP
;			   This routine will return with ESI the return addr.
;			   (the IP address right after the "call" instruction)
;			   which is relative to the 32 bit code descriptor.
;			   By calling this routine & adding the displacement
;			   between the the label we want to reference & the
;			   return addr. we can use cs:[esi] to refer to the
;			   label even though the caller does not pass a good
;			   descriptor for us. This is implemented to solve the
;			   UNIXWARE installation problem.
;
;			3. For unknown reason, the MS '$PIR' must be placed
;			   in a address in F000 segment not too low in order
;			   for the SystemSoft's PCMCIA DOS driver not to hang
;			   up. So we linked the PCI21TBL.OBJ just right before
;			   PM_RAM.OBJ.
;
;			4. The linked value of the IRQ table should reflect
;			   the PIRQ# register. That is, if the IRQ router
;			   is PIIX, link value 1 should be 60h, 2 be 61h & so
;			   on. These special link value are defined in
;			   COMMON.EQU.
;
;			     Engineers porting new chipsets please refer to
;			     COMMON.EQU, searching "M5143" for special 
;			     link values where "M5143" is switch for ALi's
;			     Alladin 4 Plus.
;
;			5. All onboard devices which requst a IRQ in its
;			   Cfg Space 3Dh must be reported in the IRQ routing
;			   table.
;
;			     Engineers porting new chipsets please refer to
;			     COMMON.EQU, searching "M5229" for IDE routing
;			     & "M5237" for USB routing. Both of them are
;			     switches for ALi's Alladin 4 Plus.
;
;			6. All devices that will be completely hiddened
;			   when disabled must not be reported in the IRQ table
;			   (e.g. USB controller of PIIX3)
;
;			     We place the USB IRQ link table at the end of 
;			     whole IRQ table. At the end of POST, we change
;			     the table size by checking the existance of the
;			     USB devices.
;
;R01	08/04/97 RAY	Support also the notebook project with card bus on board
;R00	08/01/97 RAY	Initial Revision for PC 97 test
