Table A-1. ENV Command Parameters (Continued)

ENV Parameter and Options	Default	Meaning of Default
Memory Search Delay Address	FFFFD00F	The default address is
		$FFFFD00F. This is the
		MVME197LE GCSR
		(global control and
		status register) GPCSR5
		as accessed through the
		VMEbus A16 space and
		assumes that the
		MVME197LE GRPAD
		(group address) and
		BDAD (board address
		within group) switches
		are set to “ON”. This
		byte-wide value is
		initialized to $FF by the
		MVME197LE hardware
		after a System or Power-
		on Reset. In a multi-197
		environment, where the
		work pages of several
		Bugs are to reside in the
		memory of the primary
		(first) MVME197LE, the
		non-primary CPUs will
		wait for the data at the
		Memory Search Delay
		Address to be set to $00,
		$01, or $02 (refer to the
		Memory Requirements
		section in the Debugger
		General Information
		chapter of this guide for
		the definition of these
		values) before
		attempting to locate
		their work page in the
		memory of the primary
		CPU.
Memory Size Enable [Y/N]	Y	Memory will be sized
		for Self Test diagnostics.
Memory Size Starting Address	00000000	The default Starting
		Address is $0.
