[gPXE] Near last step of flashing e1000 ROM with Wifi gPXE the USB stick won't boot

[J C]

dosboot.img (FreeDOS boot disk) is found near the top of this page http://etherboot.org/wiki/romburning/intel under the heading "Preparing the Tools". I think I got it some time back. It is not ava on the http://rom.etherboot.org/boot/dosboot.img site link anymore.

I'll look for info on dosboot.img and try it on a much older PC.

Everything looks good except...  What is 'dosboot.img'?  Where does it come from?  Does its vendor suggest that it can be DDd to any USB stick and that it should be expected to work with any BIOS?
