I have had very good results from almost all of the  currently shipping  
Soekris products, and am generally a very happy customer.  But I am 
having  particular difficulty getting a bootable image into the net4526 
I purchased recently.  I have read everything I can find on PXE booting  
any variant of 'BSD and such PXE documentation as I have been able to 
find but cannot get past  a  particular error.  The com output  I get 
after a reset is as follows:

I am particularly troubled by the line:
   PXE-E79: NBP is too big to fit in free base memory

While I assume NBP means something like 'network boot prom', I have not 
been able to find it defined anywhere - especially in Intel's 
'documentation'

On the server side I have DHCP and PXE set up as indicated in the 
m0n0BSD Hacker's Guide, the m0n0Wall documentation, the PXE etherboot 
HOWTO, and the FreeBSD documentation, and various other 'authoritative' 
sources both great and small. Where they (frequently) contradict each 
other, I have attempted to try all the permutations and combinations.  I 
am using a FreeBSD 4.10 machine as the PXE boot host.

But somewhere there is something I just DON'T  get. So I find myself 
peering into the abyss of despair.

Can anyone point out the obvious point that I must be missing?
