When I needed to copy some stuff onto a "boot disk", this worked fine with
my Feb 1 kernel. Installing Win95 on Bochs OTOH and mounting the
resulting disk image (was a pain, didn't work)....

As I said above... it was rather weird that the hdd image I was using
wouldn't mount when I vnconfig'd it and mount -tmsdosfs'd it.. it claimed
the bpb was invalid.. Win95 under Bochs grok'd it..

The only floppy oddity I've noticed of late was when I tried making disk
images of 1.68mb disks.  dd if=/dev/fd0.1720.. worked fine and generated
disk images fine.. but generated a LOT of error messages towards the end
like:
