Indy bootstrap tftp problem

Indy bootstrap tftp problem

[Andrew Cannon]

I am trying to install Linux on my Indy using the network boot procedure 
described on the debian site at 
<http://www.linux-debian.de/howto/debian-mips-woody-install.html>

This is not getting very far because the tftp load of the bootblock 
fails with the Indy bootrom reporting "ip fragments error" for each tftp 
reply packet that arrives (with debug enabled). Does anyone know what 
might be happening here? Is this a known bug in the bootrom?

More info - tcpdump on the server shows the tftp reply packets with 
blocksize 512 being sent out so there doesn't actually seem to be any ip 
fragmentation happening. Booting IRIX and running 'tftp get' works ok so 
it's only the rom that fails. Oh and this is quite an early Indy, so it 
may well have a buggy rom.

Any help appreciated. thx

Some Indy bootroms do not cope with the "don't fragment" bit (DF) being
set.  If the tftp server is Linux
