floppyload fails on 486 using etherboot-4.5.6

["ACS" <as@bart.nl>]

I tested 3 ROM images on 486-66. after:
"Loading ROM image...." system hangs
(no caps lock light , no CTRL-ALT-DEL)

486-33: same problem

I only ran the makefile , nothing altered
Actually , I did the same as on 4.4.5 , but never had this problem on that
version.

When I take the diskette to a P133 it functions right away.
(at least it starts probing for an adapter that isn't in it)

I already tried  using the floppyload.bin of the 4.4.5 package

PS:
Why is the floppyload.bin renamed to floppyload.bin.pre?
This name should be changed in the read me as well.
It contents changed as well

suggestions....?
