Subject: Re: Can disks be copied using only one RL02 drive?
Henk thinks creating a RAM disk would work, and
copy files
but I don't know anything about RT-11.
That might work, but I don't think you can use RT-11 to write
the system area when fiddling packs like that. If you had a
different boot medium, floppy, say, you could treat the RL02
drive as a data volume, then it wouldn't matter. The RL02
just becomes another drive at that point.

Charles did not tell completely what I suggested, but since
I am not sure how to do it either, I would like to know ...
I also suggested the obvious ones, get the 2nd drive connected
and do some kludge work on the READY/UNIT indicator/plug.
Since Charles' 11/23+ has 4 Mb of memory ... I remember I once
had a visitor (some 5 years go!) who showed me how to use the
extra memory (core) in my 11/35 as a "RAM disk".
I don't remember which RT11 command(s?) he used, but creating
a RAM disk is definitely possible! So, if you copy the system
files that you need to run RT11 to the RAM disk *and* you can
boot RT11 from that RAM disk, you can use the rest of the RAM
disk space to copy a few files from the RL02 disk, swap the RL02
disk and copy the files from RAM to disk, etc.
You need the RAM disk for RT11 too, because you can not simply
swap the RL02 disk, because RT11 is running from it!
Ethan did point that out.
So, here is the question I have. After creating the RAM disk,
and copying the necessary system files to the RAM disk, is it
possible to *boot* from the RAM disk, like .BOOT dev:RT11FB.SYS ?
And what would "dev" be? I also would like to know what commands
create the RAM disk!
thanks,
- Henk.
