LUN of a disk/tape
device currently
supported by the Bug.
Default is $0.
This is the address
where the network
interface configuration
parameters are to be
saved/retained in
NVRAM: these
parameters are the
necessary parameters to
perform an unattended
network boot.
This is 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-197
environment, each
MVME197LE board
could be set to start its
work page at a unique
address so as to allow
multiple debuggers to
operate simultaneously.
Top limit of the Bug’s
search for a work page.
Must be a multiple of
the debugger work
page, modulo $10000
(64KB).
There will be no delay
before the Bug begins its
search for a work page.
