The number of dots indicates that it loaded the right amount of data (four
tracks, of which the last one is only read partially).

Does it crash with the cursor behind the dots or with the cursor in the next
line?  I'm a bit surprised that the changes affect different processor
families in a different way.  I know that bootsect doesn't work on a 8086/88
because it uses instructions like pusha/popa and shl cx,9, which need at least
a 186/88.  But a 486 should have no problem.  Currently my bet is that there
is some BIOS incompatibility - either the default stack location or somesuch.
But that is just a stab in the dark. I'll see what you report back on this mail.

That should be OK, if the ROM image size (not including the 512 byte floppy
loader) is at most 32K.

Did that work? Preparing the image file by hand is quite simple, just a "cat"
of the floppy loader and the ROM file. Noone said that these have to be from
the same release. If the 4.4.5 floppyload would work, but the 4.5.6 one not
this would give a hint.

Well, there is no special reason at all behind this any more - the old name
used to be a problem while I rewrote the Makefile.  It was just annoying that
the precompiled file was deleted by "make clean" and possibly overwritten if
a recompilation of the shipped binaries was requested.  All that remains is
the "bug" in the docs and the (implied) meaning of "precompiled".
