[Samba] Probs with Intel NetportExpress

[Dirk Beckmann]

Hello,
i've bought an Intel NetportExpress and now i'm stuck booting the box.

I used the Netportmanager on a Windows box configure the NetBios path
to my OpenBSD Samba server. 
Now the problems begin, the Netport does not download anything from 
the samba server.
It sends frequently broadcasts - to connect to the Netbios name
as i would guess.
(0:aa:0:52:87:3b is the MAC adress of the printbox)

tcpdump: listening on xl0

....

smb.conf:
...
[printserv]
        comment = Printserver Remote Boot Share
        path = /home/printserv
        writeable = Yes
        create mask = 0555
        guest ok = Yes
        hosts allow = 
...

Has anybody a NetportExpress booting from a *ix based server?
If so - plz send me (a part of) your smb.conf.

Thanx
