Problems on TS-101

Hey there,

I really like the idea of having netbsd on my Qnap TS-101 box. 
Unfortunately I am struggling with getting the installer to boot.  I 
tried various altboot and netbsd-INSTALL images and ended up with netbsd 
from HEAD/201108250420Z and altboot from 
ftp://ftp./netbsd/.org/pub//NetBSD//misc/phx/sandpoint//altboot/./bin/.gz .

Here's the output:

As you can see, the transfer of the image stops and five timeouts are 
displayed. The complete process should go something like this:

    loading "netbsd-INSTALL" 5143540+110580=0x503068

The Wireshark output related to this error is:

    TFTP    Error Code, Code: Disk full or allocation exceeded, Message:
    \000


I tested it with tftpd-hpa under ubuntu and tftpd32 under windows with 
the same error.

I would be glad if you could provide me some help.

Thanks a lot!
