What version of PXELINUX are you using?
Also, Gene's earlier question still applies:

The messages you got mean the PXE stack failed to download and transfer
control to the next NBP, which is what PXENB_RESTART_TFTP should have
done.  Unfortunately, the status code 0x0001 means "general failure";
your BIOS isn't providing any more detailed information.

This could mean the TFTP server is configured improperly, or doesn't
have the file you asked for, or some firewall is interfering, or any
number of other things.  It could also mean a problem with your BIOS.
