Hi,
I have OpenBSD running on an Optiplex 7020 with the most recent
stable version of Libreboot (20240612). The built-in ethernet works
for a Linux ISO, but not for OpenBSD. Looking through OpenBSD
mailing lists, I suppose that Libreboot does not initialize the
built-in ethernet as much as OpenBSD requires.
Please let me know if you have any experience with this, or if
you have any ideas. I would be happy to do some tests.
The dmesg gives several memory address conflicts and for the ethernet
it gives:
em4 at pci0 dev 25 function 0 "Intel I217-LM" rev 0x05: cannot find mem
space
Here is most of the dmesg:
