PXE Boot HP X2 210 (Hybrid tablet Windows 10 Pro)

[Sebastian Roth]

@Matthieu-Jacquart I really hope I remembered correctly the change I made more than a year ago. Just compiled a new kernel which does not call the hanging function setup_efi_pci(). This is very ugly but seems to be a way to workaround this dang HP firmware bug! Find bzImage_disabled_setup_efi_pci here.

Turns out HP released at least two new firmware versions but didn’t include the (probably very tiny) fix we worked out together with them. As they even provided fixed firmware blobs to try out I have no idea why this didn’t make it into their official code base?!?

@sebastian-roth You’re just a master chief Seb ! It works perfectly !
Do you think there’s any way to contact HP people to modify bios, or maybe (but I’m dreaming) just add an argument in fog Web UI “Host Kernel Arguments” ?
Thanks a lot, once again
Matthieu

@Matthieu-Jacquart I am sorry but disabling these setup_efi_pci routine is a really dirty hack to make it work on those HP devices. We’re not going to include this into FOG not even with a “Host Kernel Parameter” thing.

Sure I can send a message to those same guys but I kind of doubt that the fix will ever make it into the official firmware - whatever reason they have?!?! Would you mind preparing a piece of text so I don’t have to do this alone? Just read through the mail I sent you and put together a couple of lines. I’ll finish it and send it off then.

[Matthieu Jacquart]

@sebastian-roth Ok thanks, I’ll email you as soon as possible.

Did you ever get a response?

[Sebastian Roth]

@Wayne-Workman No, they didn’t get back to me. But Matthieu just had another try and sent a new message two days ago. Let’s see what happens this time.

We have an old firmware binary that might be useful to flash those devices with a fix. Though this has never been officially released and is missing other fixes that have been released since then. Let me know if you need help on this.

@sebastian-roth @Wayne-Workman No news for the moment but I’ll keep you in touch

Hey Matthieu, i also try to deploy HP X" 210 Tablets.
I tried to download the mentioned bzImage_disabled… but the link is broken.
Can you provide this image to me?

@BSZAdmin Wow, this is bringing up a really old topic! Though I compiled this one off kernel I don’t have it anymore.

Last time I wrote:

I might be able to do this again with a newer kernel version. So which version of FOG and which kernel version do you currently use?

[Matthieu Jacquart]

@bszadmin Hi, old subject, this file was necessary few years ago to deploy image on X2 210 G1, but for at least 2 years everything works fine with official HP bios and Fog 1.5.
What concern do you meet ? is it for X2 210 G1 or G2 (G2 always worked fine).

@sebastian-roth
Good morning, sorry for bringing up ths old topic.
The clients are HP x2 210 G2 as @Matthieu-Jacquart guessed.
The fog process stops here:

We are running fog 1.5.6 with kernel 5.10.50.
Thanks for the support and the great work.

Pretty old version of FOG, hmm!? You might want to grab newer version iPXE binaries from github and see if those work with your HP x2 210 G2.

@sebastian-roth
thought it is not too old. My fault…
We will update the server and see what happens.
Thanks meanwhile.
Have a nice week
