Changing MTU for pxeboot

[Olivier BONHOMME <obonhomme nerim net>]

Hello everybody,

I am trying to install a Fedora Core 6 using pxeboot. The problem is 
that the server which contains the install images has a MTU set to 9000. 
Then when I try to download the install image on the system which I try 
to install, the transfer fails because I have a MTU 9000 on a side and a 
MTU 1500 on the other side.

I saw on the Redhat bugzilla, that it was possible to send a new MTU 
parameter to /sbin/loader and anaconda using the command line. I tried 
to put mtu=9000 on my pxelinux.cfg file but it doesn't seem to work.

Does somebody has this problem and does somebody know how to change the 
MTU parameter on /sbin/loader and anaconda in a automatically way ?

Thank you for your answers

Best Regards,
