You might open the floppy drive and look at the heads directly.  With
most of the floppies I know this is no big mechanical probblem.

Both should be identical down to the bit.

I wouldn't wonder if the Deskstation guys modified the DMA logik of the
board in some difficile way ...  I'll have to talk to them again also.

            I'll have to take a look at that when I get a free minute.

Doom ?-)

                                                             so I haven't

The SNI stuff is in 1.3.98.  I'll be doing a little hack session the next
night and upgrade to 1.99.8 aka pre2.0.8.  1.99.7 is already running :-)

The SNI looks enough like a "normal" Linux machine so that Drew
attempted in Berlin to copy some binaries on it.  If not a permission
denied had stopped him a "wrong architecture" would have done :-)  He's
not the only guy who got fooled by the machine; like the other machines
the SNI was abused as stupid telnet terminal for the most of the time ...

I'll have to excuse once again for not doing all the things that I've
promised on the mailinglist and some people in private.  I recently had
a car accident and 'till I've can replace it (Send me all your cars $-)
public traffic/biking costs me some extra hours each day.

Anyway, email get's outdated as it is being written - 1.99.8 is running
on the SNI now ...
