There is a setup program which has to be run under DOS :-(  This was
the reason the bootrom wasn't recognized at all in the beginning (is
there a hint on that in the READMEs?).

Whatsoever, we set the bootrom size to 32 kB, which seems to be
properly saved to the card's flash rom (possible options are 'no
bootrom', 4 kB, 8 kB, 16 kB, and 32 kB).  Using netboot-0.9, we have
this weird behaviour that the size seems to be altered; with
netboot-0.8.1, the bootrom is not touched by the NIC.


What could be responsible for this difference?
