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 > > ср, 9 сент. 2020 г. в 10:52, Clay Daniels <clay.daniels...@gmail.com>: > > > > I'm just trying to read what bios info I can: > > > > MSI X570-A PRO (MS-7C37) > > AMD Ryzen 7 3700X > > FreeBSD fbsd13 13.0-CURRENT FreeBSD 13.0-CURRENT > > > > root@fbsd13:~ # flashrom -p internal > > flashrom v1.2 on FreeBSD 13.0-CURRENT (amd64) > > flashrom is free software, get the source code at https://flashrom.org > > > > Using clock_gettime for delay loops (clk_id: 4, resolution: 1ns). > > Found chipset "AMD FP4". > > Enabling flash write...
