How do you start the tftp server?
In my xinet.d tftp config I have set '-s /tftpboot' to the boot params.
I then specify the following in my dhcpd.conf
host somehost {
filename "pxelinux.0"
hardware ethernet 00:00:00:00:00:00;
fixed-address 123.123.123.123;
};
my filesystem looks like:
/tftpboot/
/tftpboot/pxelinux.cfg/
... and the pxeboot config files in here
/tftpboot/pxelinux.0
