[K12OSN] Compaq Deskpro not PXE booting

[Joe Guenther]

Jesse,

That was a great link ... that is what makes this list so phenomenal!!  So
now the question is, ... do I just disable the onboard NIC and throw in a
standard 3com905c ... certainly more simple.  But hey thanks for the
incredible tip.

Joe,

I had an identical problem when setting up an Intel cn430tx board with
onboard nic and Landesk Service Agent 0.99. Landesk Service Agent 0.99 is
known to be buggy. The solution that worked for me is outlined at
http://syslinux.zytor.com/hardware.php#network.

Briefly, disable path MTU discovery on the boot server by changing the
content of /proc/sys/net/ipv4/ip_no_pmtu_disc from 0 to 1.
To do this. as root, run echo 1 > /proc/sys/net/ipv4/ip_no_pmtu_disc  from
the command line. If you ever reboot your server you will have to rerun this
command.

Disable the blksize TFTP option on your TFTP server by adding -r blksize to
the server_args in /etc/xinetd.d/tftp
The line in my system is:

server_args	=  -r blksize -s /tftpboot/

You'll have to restart tftp for the changes to take effect.: /sbin/service
xinetd restart should take of that.

This works for me...hope it does for you.

Good luck!
