I just ran across this article from July 2017 as I was researching how to solve that problem on my old HP Pavilion a1600n, I downloaded the most recent .zip file ver 5.0.15. However, after installing the Plop loader plpbt.img on a floppy disc as well as burning plpbt.iso to CD, neither works on this PC. The initial boot selection menu comes up as described in the article, but as soon as I select “USB”, the program freezes. The article also suggests to try plpbtnoemul.iso but that file does not appear to be contained in the .zip that I downloaded.
I’ve tried to search for alternatives to Plop but so far I have not found any, My dilemma is that I’ve created a USB bootable backup for my system, but now I have no way to use it in the event I need to do a restore.
I’m hoping someone can shed some light on this issue. Thanks
