"Etherboot" exponentially increases the timeout between retries, while
also introducing some randomization. This technique is suggested for
most network related timeout handling and usually helps to deal
gracefully with resource starvations. I do not know whether "netboot"
uses a similar algorithm. If in doubt, just burn a couple of EPROMs
with an "etherboot" image (or temporarily boot the image from floppy
disk) and test if it works better for you. Both "etherboot" and
"netboot" have similar features but details do differ --- so depending
on your specific needs either of them might be more suitable for you.
