So this won't work. LPC programmers are not cheap (and that will likely not change as they are rarely used these days).
However, I wonder if you need a programmer at all. As long as both
machines are still booting, you should be able to read/write the BIOS flash with flashrom's "internal" programmer option. If in doubt, you can send us a verbose log (or paste it on paste.flashrom.org) taken with `flashrom -p internal -o logfile.txt`. Only if something goes wrong and one of the machines isn't booting anymore, you should need a separate programmer.
Shit happens. However I did purchase that programmed BIOS chip, so I could always unbrick the machine.
If you need a programmer, I'm not sure if I can give a good recom-
mendation. There is the teensy option [1], but it seems pretty much DIY. What many people do (and succeed) is hot-plugging these flash chips, but it comes with some risk of course. You can boot a PC normally, then, while it's running, swap flash chips and then read/write the second chip like you would during a BIOS update.

Thanks for the pointer. Of course, it had to be a teensy board, since all I have are arduinos and bluepills.
I'm just beginning to play with electronics so perhaps in the future something fast and dirty could be built on a protoboard. These programmer things look like good beginner projects. Will see.
Anyway, thank you very much for the information.
Best regards
