Ivan, thanks for the useful info. Your explanation likely tells me why I
can't see my bios chip. I just looked and the little usb devices are
available from Newegg where I got the parts to build my Ryzen 7 machine.
Before I order one, do you or anyone else on the list have suggestions on
what to look for in a usb ch341a external programmer? Newegg has a wide
variety.

You may have noticed my https://paste.flashrom.org/  lspci file. I added a
Ubuntu Linux disk as FreeBSD doesn't do lspci, just pciconf. I also tried
(twice) to load a pciconf -lvb from FreeBSD, which is there but called
lspci ;-(

Anyway, thanks for your help,
Clay
