Hello,

this is my workstation machine and here are some random notes:

- Updated Bios to the latest
- Sound appears not to be working, but i have not spend enought time
debugging it. Perhaps I am doing it wrong.
- Sometimes after cold boot(?) the Intel 82579LM NIC seems not work.
It's assigned correctly to the netvm and is also listed by lspci, but
ifconfig -a does not show it. Further digging revealed, that dmesg is
getting an -3 error. It seems like the NVU(?) have to be updated and
this is a known error. Need further investigation. Next time i will save
the error message ;).
- Having 8GB RAM with Qubes is no fun. You have to upgrade.
- Onboard Sata Marvel Raid "controller" does not work in linux. The
devices are always shown spitted and not as Raid. Best not to use the
"raid" logic.
- You can disable each usb port specifically in Bios
- Bios passwords are [a-z0-9]
- VT-x/VT-d + TXT + TPM Support


The machine supports Intel ME and APM. As far as i understand the
purpose of these abbreviations is to do remote management with with
Intel ME and APM. Can anything of it be used to "get" more security
locally, or should they be better deactivated? Information on the both
topics is pretty rare.

Try unplugging your audio cable from the sound card, wait a few seconds,
then plug it back in. This is how I get audio working on my system since
Qubes got FC20.

Hey,

added to the HCL: https://www.qubes-os.org/trac/wiki/HCL?action=diff&version=166

Did you install and test AEM?

Best Regards,

I'm glad to be helpful :). The issues you are mentioning in the wiki,
are a little bit overrated, at least the network and raid issue.

I could not reproduce the Network issue anymore, across a few cold
starts. I will observe the issue further.

The Raid is not worth mentioning, because it appears to be a software
raid. I had occasionally used marvel onboard hardware raids, they worked
with qubes.

> Did you install and test AEM?

Installed. I am working on it.

Notes till now:

- There are 3 states in Bios -> Security -> TGC Settings for the TGC
- Enabled <= The one you want
- Inactive <= It's visible to OS, but you can't take owner ship of it
or do anything(?) with it. (Default)
- Disabled

- To clear the TPM chip you have to execute tpm_clear and reboot to
Bios. In the TGC Settings choose the Clear TGC Option, set to Yes, save
and reboot.

It's back. But it appears randomly. Here is the dmesg error msg:


[ +0.004350] e1000e: Intel(R) PRO/1000 Network Driver - 2.3.2-k
[ +0.000007] e1000e: Copyright(c) 1999 - 2013 Intel Corporation.

[ +0.454075] e1000e: probe of 0000:00:00.0 failed with error -2

I'm pretty sure i have seen the issue already some where.

Taking ownership of the TPM chip worked flawlessly.


- I assume i do not need a SINIT module? At least for E5-2650 on C600
you do not need one.
https://software.intel.com/en-us/articles/intel-trusted-execution-technology#comment-1787459
So i can skip this part?

- I do not want to use an usb stick can, so i just replace the
apropriate device with my current one, right?

- I already have a loot of boot options like AEM and tboot, which do not
work at the moment. Is it because i installed anti-evile-maid or is it
because i run yesterday grub2-mkconfig to get discard working? Should i
just ignore them and follow the README?

Most likely, but to be sure check if PCR 17+ are extended with anything (so no
FF...):
PCR17 DRTM and launch control policy
PCR18 Trusted OS start-up code (MLE)
PCR19 Trusted OS (for example OS configuration)
PCR20 Trusted OS (for example OS Kernel and other code)

Right, but instead of antievilmaid_install you can use already existing device
by changing its label and executing part of that script manually:
e2label <DEVICE> "antievilmaid"
mkdir /boot/antievilmaid
cp /var/lib/tpm/system.data /boot/antievilmaid
chmod -x /etc/grub.d/20_linux_tboot
chmod -x /etc/grub.d/20_linux_xen_tboot
dracut -f
grub2-mkconfig -o /boot/grub2/grub.cfg

When using on-disk /boot, you most likely want to set SRK key.

Yes. Note that above chmod -x calls will remove some unneeded entries.
