[syslinux] Could not find kernel image: linux

[Boris Girsch]

So that's me again.
I searched all the time in the maillists and so on and found this 
documentation
http://unix.derkeiler.com/Mailing-Lists/FreeBSD/stable/2005-06/0110.html
did everything like it was described there but when i try to boot with 
pxelinux
i get following:

could not find kernel image: linux
boot:

my tftpd was started without chroot, so the path to kernel is 
/tftpboot/memdisk
and the path to pxelinux.cfg is /tftpboot/pxelinux.cfg/01-00-00-00-00-00-00.
there are no firewalls. KNOPPIX boots just fine.
Can anybody point me to my mistake ?

-------------pxelinux.cfg----------------
label fbsd
kernel MEMDISK
append initrd=fbsd54.img
