I'm just dd'ing it as well. No problems reported, the image is

to be a problem), and all that. It's an image with which I can
do a "boot rq0" from SIMH and it starts up with no problem, but
when I do the CQD's bootstrap (which looks like it just reads
the first block to address 0 and goes with it), I can verify
that I get 512 bytes of zeroes, which isn't what's on the first
block of the disk.
It's bedtime here, but in the morning I'll hook up the serial
port and make sure I haven't done anything funky with the CQD's
partitioning setup. If there's anything else to check up on,
I'd be glad to hear about it. This is the first time I've
gotten around to trying to boot anything off the CQD since I
fixed the firmware bug last year, so I'm working a bit blind.

I have a bootable 100MB RSX-11M image in SIMH
that I'd like to blast onto a Zip disk and boot through my
CQD-220. I'm running a build on SIMH that's essentially
identical to my machine, so it should be straightforward,
but when I try to boot my disk, I get a "not bootable"
response from the ROM (the activity light on the Zip
drive does flash momentarily, so I know something is
going on, but it doesn't look like it's taking enough time
to actually seek anything (and when I boot through the
bootstrap provided by the CQD-220 ROM, I get a HALT
at 000002, which tells me it's probably getting all zeroes).
How are you transferring the image to the ZIP? With Linux, I can dd an image created with
E11 to the ZIP, and it boots fine with a CQD.
