Hello Paul,
I walked into the dump of your CF image, and everything
looks
correct
: Minix boot blocks, geometry constants, filesystem,
root
directory
and kernel image.
Could you please tell me the size of your low memory,
and
confirm the
processor is a 8088/86, not a 80186/286 ? After reading
the
code
of
the boot blocks again, I found two potential failures
related.
Also, if you could tell me the BIOS version & date, for
me
to
have a
look in the IBM manual ?
Thanks,
MFLD

Hi Marc,
The bzipped file is so small I'd try to attach
it
to
this
message.
The other attachment is the diff of all of my
changes.
I must admit, I was looking into wrong places.
As I
mounted
this image, it
indeed contains MINIX filesystem with /linux
file
in it,
and
that file
indeed has magic string "ELKS" at offset
0x1E6. So
I
suspect,
load_zone()
does something wrong.
Note that I wasn't able to boot from 360k
floppy
either
(with
the same
outcome!), despite all the changes as in the
patch.
Cheers,
Paul
