;			DRAM plugeed.
;R52	08/08/96 KVN	Added customer EPA LOGO support

;			     - Keyboard is lock
;			     ====> no error message but still wait for "F1"
;
;			Reason:	this is due to Keylock error is recorded
;				in FIXED_ERROR[BP], the old code checked
;				for FIXED_ERROR[BP], FLOPPY_ERROR[BP]

;			This is stated in PCI specification & is strongly
;			request by PCI SIG.
;R32	04/27/96 RAY	Check Update-In-Process bit when writing to RTC
;			This will prevent system from accidentally set the
;			system time to default year: 1996
;R31	04/23/96 DNL	Modify code to save space
;R30	04/19/96 RCH	Added routine to display conflict I/O for COM & LPT
;			ports and halt system for user to change CMOS setup
;			for super I/O. Note: it need a routine named
;			"Disable_SuperIO_ComLptPort" in .SIO file
;R29	04/17/96 RCH	Added a hook to do special program before VGA ROM
;			initial.
;R28	04/12/96 TNY	Add Higher_120MHz_Tbl definition.
