Hi Kjeld I'm afraid the PXE MBR is started twice but never finishes. Three observations to support that: There are less dots printed after the "Loading ROM image" than when I boot from the PXE floppy. I get the "Loading ROM image" line twice but none of the PXE messages that show up on a PXE floppy boot. The file containing the etherboot MBR is downloaded from the TFTP server only once, not twice.
So differentiating between TCP/IP BOOT-PROM filename and PXE filename is not the problem (yet, unfortenately :-) The machines don't have floppy drives to prevent users from booting their own software.
