days. However,
I won't be using the nice WQESD ESDI controller that I've
got that makes partitioning disks easy. So I want to make sure I
understand how partitioning works under RT-11.
Doesn't it do the partitioning in hardware anyway? Of course that is
easy... they become separate units... That should be
.SQUEEZE/OUTPUT:DU0: DL1:
.COPY/BOOT DU0:RT11FB.SYS DU0:
Whoops, manual even says that on the copy I see. I guess I literally need
my eyes checked as I read the COPY/BOOT wrong.
Squeeze is a faster way of doing the copy when the
output volume is
a freshly initialized volume. You could do it with a COPY/SYS...
Ah, OK I understand, the COPY/SYS is how I've done it previously.
There are a number of factors involved... you need to
ensure that the
partitioning in the DU driver you are using to write to the DU device
is the same as the DU driver which gets written *to* that device. If
not, you could write the data just fine, but not be able to find it
easily.
Now is this the same specific copy of DU.SYS? In other words should I be
booting off RL, setting the partitions, then init'ing the drives, then
copying? Or is this simply saying that DU.SYS vs. DUX.SYS will have
problems?
An example of this might be having a
specially-partitioned XM version of
the DU driver. You use it to copy a system to some other partition,
but you set it to boot RT11FB (which uses a different copy of DU -- the
one built for SB/FB) and then boot the volume... when it gets up far
enough that it tries to use the FB version of the handler, it references
an entirely different partition.
Based on this I gather it's not a good idea to switch between monitors once
you have the disk set up? Terrific.
Thanks,
Zane
