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

I’ll try to buy one USB 3.0
Please let us know how that goes. We really need to get into the USB 3.0 stuff.
-
@Wayne-Workman As Matthieu said this is only possible with the patched bzImage_rb. But it’s a quite ugly hack I think and I have absolutely no idea if this will cause issues on other devices. Up to now it looks like the freeze is caused by a bug in the UEFI firmware but we don’t have a clear confirmation yet. Will take some time. iPXE is definitely not an issue on these HP X2 210 tablets and therefore trunk version is fine except the linux kernel.
-
@Wayne-Workman I think we are going to buy this one (Realtek RTL8153).

Any know issue with this chipset ? -
Try searching the forum for RTL8153. From what I know several people have trouble using RTL8153 based USB NICs even in BIOS legacy mode. I don’t think UEFI will be easier. Probably best to start a new discussion on this as it might be a long way to go just as this one was.

@Sebastian-Roth Ok, I’m going to this this one today : http://www.startech.com/Networking-IO/usb-network-adapters/USB-3-to-Gigabit-Ethernet-NIC-Network-Adapter~USB31000S
chipset ASIX AX88179EDIT : Sh**t, Tablet didn’t recognize USB 3.0 adapater at boot…
Let’s go to find another adapter !!! -
@Matthieu-Jacquart Give it a go if you are keen! And please open a new topic on this so we don’t loose track of the main point in this discussion here (linux kernel on HP X2 210).
As a start you might want to read through this detailed discussion on USB NIC iPXE booting! Start with the very last post on page three that says “USB support is starting to arrive in mainline iPXE” on Feb 2015! I think you are really lucky to have a 100MBit USB NIC booting on your tablet in UEFI mode actually capturing and downloading images with FOG. This is more than a lot of other users have achieved so far. It always depends on the device’s BIOS/UEFI firmware to support this particular USB NIC. Then iPXE would need to run on this as well.
Anyhow, try some of those gigabit adapters that are available and start a new discussion on this. Hopefully you are lucky enought to find one that works as well!
-
@Sebastian-Roth ok, and thanks again so much for your help.
Do you think we can mark this topic as resolved, or we are waiting for a fix from HP / Insyde ? -
@Matthieu-Jacquart Good question. I’d better leave it as unsolved as this really is just a quick dirty hack and I am very afraid of pushing this into our main kernel. Talked to Tom Elliott about this already and I think we should better wait. Do your cloning as this is working for you now and I will get back to you for some more testing when we hear back from the firmware guys I’d say.
-
@Matthieu-Jacquart The firmware people got back to me asking about the BIOS version. Can you please find out and tell me?

Hi,
somehow this thread stopped. Was the discussion moved? I’m also interested in the topic. I have Linux running on the tablet. First I bootet with Ubuntu 16.04 beta release to be able to install ArchLinux from there. Ubuntu runs stable but does not show the battery status. ArchLinux runs instable, but does show the battery status. The problem is that the i2c designware platform module causes a kernel panic, and then freezes the system completely. I guess that’s also why it is not possible to boot any other Live system.Here you can find the dmes output: https://bugzilla.kernel.org/show_bug.cgi?id=113291
It looks loke there is a problem with a semaphore. Unfortunately, I’m not too familiar with the i2c module nor the kerenel itself. Could someone give me a hint what to try out?
Disabling the kernel module, as given under the link above fixes the issue, but causes other problems.
P.S.: Written from my x2 210 running ArchLinux

@schnecki We are more than happy to help people solving their linux problems. But please understand that this forum is about FOG and we focus on getting FOG or FOS (the buildroot linux system at its base to do the imaging) to run on the devices. We only have basic knowledge on kernel stuff and we won’t be able to help you with this one I suppose.
The OP was about the linux kernel freezing when trying to enumerate PCI devices booted in UEFI mode. I guess you don’t see that issue as you probably use GRUB bootloader (which actually bypasses the UEFI STUB and boots the linux kernel as old school bzImage). What you ask is totally unrelated. Feel free to open a new discussion and see if anyone from the FOG community is able to help.
-
@Sebastian-Roth oh I see, I thought that might be related. But you’re right, I’m booting via Grub. Thank’s for the info though
-
Marking this thread solved for now as the OP is able to capture and deploy his tablets with the modified kernel. Although this is not a proper solution (more a hackish kind of workaround) we cannot do anything else than waiting for the people from HP we got in contact with to possibly fix the UEFI firmware!
As of now the HP devs confirmed our findings (screwed memory addresses) but we haven’t heard back from them for two weeks now. No solution yet…
-
@sebastian-roth Hi Seb and @tom-elliott, I re-open this topic because I need to deploy once again our hybrid HP X2 210, but modified bzimage that Seb provided to me (bzImage_rb) is now too old for fog (base on kernel 4.3.3).
Without this I can’t deploy our 32 hybrid, is there any way to update the bzImage_rb ?
Thanks
Matthieu -
@matthieu-jacquart Has there been any movement on HP’s part to update the uefi firmware on this hardware?
Is there a compatibility issue with the kernel your have vs the current release of FOG? Or is it just old and you want it updated? I’m just trying to understand the context.
-
@george1421 It’s a long story, but it’s an incompatibility between this HP model and fog kernel (HP never made modification for this model and last bios don’t change the problem), so the only solution in February 2016 was to modified fog kernel (big thanks to Seb for his work), and after that everyhting worked fine.
But now I want to deploy these hybrid and with modified kernel (based on 4.3.3) I’ve got fog (1.5.0 RC8) message : kernel too old. -
@matthieu-jacquart Ah ok, now I understand.
Just be aware the developers are taking a short holiday for the rest of the month. So their response will be a bit slower. Just be aware so you can adjust your schedule.
-
@Matthieu-Jacquart Oh yeah, I definitely remember this one. It’s been a long endeavor till we got this fixed. As far as I remember HP provided a fixed UEFI firmware. Just checked the mails in my archive and sent you the message via E-Mail:

Ok ! With Shell_Full.efi I was able to boot on EFI shell and to downgrade/upgrade bios, and everyhting works fine with Yu Max bios ! I was able to register hots (using ipxe.efi in DHCP options) without error, good !So I am a bit confused that you say things don’t work. I had the impression that HP actually fixed this and possibly also officially released a new firmware including that fix. But maybe I am wrong. Please read through the old message I send you via mail and let me know what’s up.
-
@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! FindbzImage_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
