Hi Kjeld Unfortenately, TCP/IP BOOT-PROM seems to be very picky on what boot floppy images to boot from.
Following your suggestion, I created a PXE boot floppy (using http://www.rom-o-matic.net/5.4.1/) that boots the machine fine from the its floppy drive. From that floppy I then made a TCP/IP BOOT-PROM boot image (using their BMIMAGE utility). That image is activated on boot, but then I get two identical lines "Loading ROM image ........ " and the machine hangs. Same result when I use the TCP/IP BOOT-PROM intermediate boot loader BPBOOT to boot the MBR extracted from the PXE boot floppy. For fun, I tried a boot image created from a FreeDOS boot floppy. That hangs the machine after printing "FreeDOS". Additional question: If I could get secondary booting into PXE to work, how could I specify the file to be downloaded by PXE? The BOOTP filename parameter is already used to tell TCP/IP BOOT-PROM which file to load for the primary boot.
