Configure and Environment Commands

Table A-1. ENV Command Parameters (Continued)

ENV Parameter and Options	Default	Meaning of Default
Network Auto Boot Abort Delay	5	This is the time in seconds that
		the Network Boot sequence will
		delay before starting the boot.
		The purpose for the delay is to
		allow you the option of stopping
		the boot by use of the Break key.
		The time value is from 0 through
		255 seconds.
Network Autoboot Configuration Parameters Pointer	00000000	This is the address where the
(NVRAM)		network interface configuration
		parameters are to be
		saved/retained in NVRAM;
		these parameters are the
		necessary parameters to perform
		an unattended network boot.
Memory Search Starting Address	00000000	Where the Bug begins to search
		for a work page (a 64KB block of
		memory) to use for vector table,
		stack, and variables. This must
		be a multiple of the debugger
		work page, modulo $10000
		(64KB). In a multi-162
		environment, each MVME162
		board could be set to start its
		work page at a unique address
		to allow multiple debuggers to
		operate simultaneously.
Memory Search Ending Address	00100000	Top limit of the Bug’s search for
		a work page. If a contiguous
		block of memory, 64KB in size, is
		not found in the range specified
		by Memory Search Starting
		Address and Memory Search
		Ending Address parameters,
		then the bug will place its work
		page in the onboard static RAM
		on the MVME162. Default
		Memory Search Ending Address
		is the calculated size of local
		memory.
