Can you install a tiny boot partition containing etherboot/gpxe<br>
(<a href="http://etherboot.org/wiki/howtos" rel="noreferrer" target="_blank">http://etherboot.org/wiki/how<wbr>tos</a>) which will then try to PXE<br>
boot indefinitely? It fits on a floppy or tiny USB, too.<br>

That would be a backup plan if we can not find something that fits in just the MBR. The local HDs already have partitions on them, they could be re-partitioned to create space for a small partition as you suggest, but that would be a hassle. We have also thought of using a USB stick, but those are unreliable and we would have to buy and configure 20-30 USB sticks.<span><br>

Unfortunately the BIOS does not re-try booting from the beginning after trying all the options in the boot order. It gives you a screen that says something like "no OS found, press any key to reboot".<div class="m_-4950683655789055139HOEnZb"><div class="m_-4950683655789055139h5"><br>
