Yes, as you remark, that should be 205MB.!

Okay, so for the time being, I stick to arm32.

The old Bt application would seem to be a little friendlier, in that
all the configuration can be performed through a nice front end,
whereas the new one seems to require manual editing of the config
files.

Right, thanks.  This document, although dated 2002/03/12 still seems
to refer to bb_trash and describes the /very/ old bb_riscbsd which
only knew about ADFS and SCSI (and required editing to handle the
Acorn SCSI card).

Well, I have managed to reproduce that symptom this morning, but
probably when messing about with different kernels/boot loaders.  I'll
have a go at it later, and attemp to report the exact circumstances.

Right, so attempting to boot from an installation kernel
(/pub/NetBSD/NetBSD-1.5.2/arm32/installation/kernel/netbsd.RPCINST.gz
- this is obviously a gzip, which I unzip with SparkFS, but it
produces another file which is also typed as a gzip and cannot be
dragged onto the BtRiscBSD config window) I end up with a screen full
of vertical stripes of various shades of grey, with a white block
cursor which will jump around between about 5 different positions on
the screen, depending on key-presses on the keyboard.  I cannot help
but think that I am almost there, but it would be helpful to see
something more meaningful on the screen!

It reports not configured, but I am not sure which kernel I was using
at the time.

Okay. I've done this, but it doesn't seem to help.  I can run
bb_(risc/net)bsd, but I still get bad disklabel and total failure to
mount. :(

Okay, well I /think/ that it has helped, but I still can't get an
acceptable disklabel on my 44GB drive, and I am getting an
installation kernel booted but without anything sensible on the
screen.  Does it help to see my configuration files?
