I doubt that SGI's tftp server implements the tsize option, which
pxelinux needs. So even on a linux box with this tftp server you
won't be able to boot anyway.

The dumps are to few for that. Give a hex dump of the
TFTP request, and a hex dump of the server's response
with the tsize option (first 100 bytes should be enough,
though ...). Perhaps the server doesn't give 
the correct size to the client.

'Opcode 6' is the 'OACK' Option (Option Acknowledgement),
so this seems correct.

BTW: Could you put some standard network card into the
client to test if it's the PXE rom to blame? A recent Intel
Pro/100 with MBA >=2  would be nice. I also have seen the
Pro/1000 boot without problems.

Josef
