Add declaration of "NO_ISA_PNP" to unsupport ISA/PNP ; cards for the system doesn't contain ISA bus. ; 2. Supplement declaration of "ESCD_SUPPORT". ;---- 08/19/98 KEN No codes' modification for this revision actually, ; just group routines for future implementation of ; new declaration of "NO_ISA_PNP" and supplement of ; declaration of "ESCD_SUPPORT". ; Old files are backup as PNP0819.ZIP. ;R15 08/07/98 RCH Added a switch to disable PnP copyright message ; display ;R14 07/02/98 RCH Added Midi IRQ assignment control for CMI8330 audio ; chip. ;R13 05/25/98 KEN Added PNP_IRQ_MAP record for the reference of the "AUTO" ; feature of super I/O serial ports. ;R12 05/04/98 KEN Always assign resources for PnP/IDE, SCSI devices ; recognized with the compatiable device ID of the ; logical device, regardless the PNP_OS setting. To ; Solve that the IDE/ESDI device of ESS1868 is showed ; error in device management of Win95, if the PNP_OS item ; of BIOS SETUP is selected as "Yes" and the IRQ12 is ; occupied by PS/2 mouse. ;R11 03/18/98 DNL To let "Award_PnP_Msg" become public ;R10 01/13/98 KEN Verify that the CSN is assigned successfully while ; doing ISA/PNP isolation to patch that the system is ; hang-up at "PnP_Early_Init" when plugged with the ; Intel EtherExpress card got from Hyosung. (The card ; seems to be damaged.) ;R09 01/06/98 RCH Added optional feature with IRQ selectable for each ; PCI slots if define "PCI_IRQ_SELECTABLE" ;R08 12/31/96 RCH Change the year of copyright from 1997 to 1998 ;R07 10/08/97 KVN Remove CPINSTAL.ASM to XGROUP from EGROUP to reduce ; compressed size for 2M BIOS code overflow (i.e. system ; BIOS compressed code cover to decompress code) ;R06 09/10/97 RCH Win 95 can not handle resource properly if user ; select "Yes" for "PnP OS" under specific add-in cards ; comination. Add a switch to force resource assignment ; to prevent resource conflict problem and the setup ; item still exist but no function. ;R05 08/08/97 KEN Later PnP/ISA initialization to shorten the time in ; POST_11s. ;R04 05/20/97 RAY Somebody do not want the BIOS to touch game port since ; it may cause their board to hang when some special add ; on card is added. So add switch: No_Touch_Game_Port ;R03 04/14/97 RCH Let UMB_AREA_SETUP also can be used for old PnP setup ;R02 03/06/97 KEN Fixed coding mistake for PNPPOST(R65), ; the SPECIAL_IO_MAP contains incorrect default data, ; and caused the 376h, 3F6h always are occupied. This ; cause the REALTEK(Avance Logic) sound card can not ; work with on-chip IDE port for CDROM. ;R01 01/07/96 RCH Change the year of copyright from 1996 to 1997 ;R00 11/15/96 RAY Initial Revision: ;
