Oops. I made a mistake in my original post. The command I typed to copy
the distribution disk was:
SQUEEZE/WAIT/OUTPUT:DY1: DY0:
That's what the installation instructions say to do anyway.
I've actually gotten a boot disk created now. It seems that the V4
version of RT-11 I was originally using didn't really do the COPY/BOOT
command correctly. I found another V4 boot disk and was able to use it
to create a bootable V5 disk. I now have RT-11 V5 and the DECUS C
compiler and linker all on one disk. This is something I could never do
with my old PDT-11/150. It only had RX01 floppies and all that won't
fit on a single density floppy. It's nice to have a bit more space with
RX02 drives!
Thanks for your help!

I've tried booting disk 1 of the RX01 distribution and that fails.
Should I be able to boot an RX01 on an RX02 drive? Also, I've tried
copying disks using:
COPY/WAIT/OUTPUT:DY1: DY0:
and then
COPY/BOOT DY1:RT11FB.SYS DY1:
Unfortunately, that doesn't result in a bootable disk. In fact, when
I did it, it trashed the system disk in DY0 even though I removed it
before and replaced it with the source disk of the copy. Does this
sound like I've got a broken drive? I seem to be able to read either
RX01 disks or RX02 disks in DY1 without any problem. Also, the copy I
made in the first step above seems to be okay. It's just that I can't
boot the disk after the second COPY/BOOT step.
What dumb thing am I doing wrong?
I may be wrong - I'm a newbie with RT-11, but if DY1 in the second
step is the same floppy as DY1: in the first step, I don't think
RT11FB.SYS exists on DY1:.
I believe you need the /SYS option to include *.SYS files in the
file copy.
