This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --DwbUr0cn8ibwh6hbguLu54hn6cP6h4VsD Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable I did 'lspci -lbcev' and found an unattached device that had the word UAR= T in the specs. The io-range of the device started at 0x50b0. So I put in my /boot/loader.conf console=3D"comconsole" comconsole_port=3D"0x50b0" hw.uart.console=3D"io:0x50b0,br:115200" just like you instructed and, yeah, I got SOL working! Really cool. Now I= can capture console output with amtterm even if system won't even boot. Thank you a lot for the instructions! :) On 13.10.2015 23:36, Ed Maste wrote: > On 13 October 2015 at 15:55, Arto Pekkanen <isoa@kapsi.fi> wrote: >> >> Ah, so AMT is some firmware (SMM) resident program that provides acces= s to >> boot console? >> >> I do have a Thinkpad T430 so it probably includes the AMT feature, I g= otta >> check the documentation and see if I can get it working. >=20 > Yeah, I'm not sure of the exact details of the implementation, but > when it's enabled it captures TCP port 16994 and amtterm on another > machine connects to the serial port AMT provides (e.g. /dev/ttyu2). >=20 > To use it I set the following in loader.conf: > comconsole_port=3D"0x50b0" > hw.uart.console=3D"io:0x50b0,br:115200" >=20 > It was a bit awkward to configure -- here are some notes on the steps > I had to take: >=20 > - F1 at boot to enter X220 bios and enable AMT > - Ctrl+P at boot to enter AMT configuration > - Default password is 'admin' > - New password has annoying requirements for case/numbers/punctuation > - I could not get DHCP to work; I assigned a static address separate > from the one used by the OS > - I couldn't get it to work until I enabled legacy redirection >=20 --DwbUr0cn8ibwh6hbguLu54hn6cP6h4VsD Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (MingW32) iF4EAREIAAYFAlYkQyoACgkQTBivhqtJa27cqgD9E+GLtw+MmN+wmPtdBQCU433t wddj3/sIt/eMxhGEOvEA/jdC16l7KZm80HV6HwsU0ByqPldYG8mCxMI53+4YIfYe =Ut2w -----END PGP SIGNATURE----- --DwbUr0cn8ibwh6hbguLu54hn6cP6h4VsD--
