Ok... I have it. The stock systems have only two RL units (see the
RT5.0 Installation Guide). So when you try to init units 2 or 3, the
requests go to unit 0 and fail. (RT11 could give better error messages,
but it doesn't.) This code snippet from the distributed sources
confirms it:
.IIF NDF DL$UN, DL$UN == 2
.IIF GT DL$UN-4, DL$UN == 4
.IIF LE DL$UN, DL$UN == 1
.IRP X,<\DL$UN>
.SBTTL *** THIS HANDLER SUPPORTS X UNITS ***
.ENDR
You need to generate a custom system to get 4 units.

I'm just letting the emulator create the file. I have three defined in the

fine, but if I delete DL2 and let the emulator recreate it, I get these
errors. So far the only way I've been able to create a working disk image
is to copy an existing one, and remove all the files.
Bob, is there anything special in your startup cmd file for the disks? This
is what I have:
[ken@raptor Disks]$ cat rt11.cmd
ATTACH RL0 rt11run.dsk
ATTACH RL1 rtv53_rl.dsk
ATTACH RL2 rt11dat.dsk
SET RL2 BADBLOCK
BOOT RL0
RL2 is the one I'm trying to initialize.

I just tried this under both RT v4 and v5.3, and it works fine on a stock
release.
However, if you either (a) fail to write the bad block table or (b) attach
an RL01-sized file to a drive that's declared to be an RL02, rather than
AUTOSIZE, RT will get very confused, and the INIT will fail.
