Jerome Fine replies:
First, to clarify, since the "RL01 Diagnostics" pack
is non-native to RT-11, PIP can't be used since it
is able to copy ONLY files. The utility program
provide by DEC is DUP.SAV and it basically operates
in two modes:
(a) Device to Device
COPY/DEVICE DVA: DVB:
options include starting block and ending block for DVA:
options include starting block for DVB:
the size of DVA: and DVB: need not be the same, so if the
destination is smaller, some of the source will obviously
not be copied
(b) File to Device OR Device to File
COPY/DEVICE/FILES DVA: DEV:FOOBAR.DSK
COPY/DEVICE/FILES DEV:FOOBAR.DSK DVB:
options include ??? - I can't remember since I have never
used them in this mode
Obviously, to hold the complete device, the device "DEV:" must
be at least 8 blocks larger than DVA:, although this is not
required. In general, if you are using RT-11 to copy only a
portion of a device to a file, I recommend setting up a logical
device under RT-11 and handling the copy as device to device.
When a file is being copied to a device, DUP.SAV will handle
that situation without difficulty in the obvious manner.
ONE other MAJOR problem. Since the diagnostic pack is NOT
the RT-11 file structure, etc., the bad block replacement
is also not available (at least as far as I know!!!). If
there are any bad blocks on the diagnostic pack, they can't
be handled automatically by RT-11. I suggest running the RT-11
to find out. If there are NO bad blocks, then just proceed.
Otherwise, you should attempt to figure out what to do. I
may be able to help if you can't figure out.
Any other questions?
