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

[Tom Elliott]

How about we get:

ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz}

First.

I’m still guessing these files didn’t download properly last time.

[Sebastian Roth]

@Matthieu-Jacquart There is no log file. You will see more output on the screen when your tablet boots up - if so. But maybe you won’t see any more information. Can you boot other clients properly? Just asking to make sure your kernel/inits are fine.

[Matthieu Jacquart]

@Tom Elliott
ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz} on fog server give me

root@FOG:~$ ls -lart /var/www/fog/service/ipxe/{bzImage{,32},init{,_32}.xz}
-rw-r--r-- 1 fog www-data 16476332 janv. 21 08:22 /var/www/fog/service/ipxe/init.xz
-rw-r--r-- 1 fog www-data 15448272 janv. 21 08:23 /var/www/fog/service/ipxe/init_32.xz

-rw-r--r-- 1 fog www-data  6759504 janv. 21 08:23 /var/www/fog/service/ipxe/bzImage32

@Sebastian-Roth Yes other client works perfectly, I deploy image yesterday and no problem. I didn’t see more output when I tried to boot on tablet

@george1421 Ok I’ll give you the result of command on Monday, for now I’m at home

[Tom Elliott]

At least now I know it’s not bad downloaded files and what not.

@Matthieu-Jacquart My intent was to not send you in 20 directions all at once. But since a live boot works, once you get the debugging information for the devs, it would be interesting to know what the output of lsblk and lspci -m are.

I’ll reiterate this. This is easy to get and important to know.

[Sebastian Roth]

@Matthieu-Jacquart Hope we’re not asking too many things here from you. But would it be possible to take a short video of the whole bootup process. Sometimes there are small hints that we only see if we have it right in front of our eyes…

Thinking about this a bit more, it would also be interesting to know what modules are loaded by what kernel modules were loaded by the live boot OS. You would use lsmod and probably direct the output into a file.

[Matthieu Jacquart]

Ok guys, I’ll give you this on monday
I hop to find a solution, It seems so close to boot properly on fog server !

OK, let’s go : Video link (really sorry for quality !!!) : https://youtu.be/ob_5qC7KRqs

For test with (Ubuntu 14.04 LTS Live) : something strange, in file explorer ubuntu just see it’s own file system and USB key, but not internal HDD (windows 10 partitions). If I use live USB key on another computer with SSD, Ubuntu displays Windows partitions (Windows 7)

While I’m not sure what this means at this moment, this disk structure does look interesting. Unless I’m reading this wrong (likely) it appears you have 2 or 3 hard drives in this device.

[Matthieu Jacquart]

mmcblk0 seems to be internal SSD with the different Windows 10 partitions, and sda1 / sdb1 were 2 USB keys

[george1421]

Where I’m confused is this.

I understand that mmcblk0 is a physical disk and it has 4 partitions. I’m good with that. But the concern (in my mind) is what is mmcblk0rpmb, mmcblk0boot0, mmcblk0boot1 which also appear to be disks and how will fog deal with them. I might suspect that mmcblk0rpmb is the firmware of this device, and then there are two disks for the boot code, maybe a primary and a backup (??) But that is only a guess.

The question would be will this confuse the fog boot kernel? I guess we will need the fog devs to answer on that one.

[Tom Elliott]

@george1421 mmcblk0rpmb is not used at all -> kernels that we have published actually prevent this disk from being seen. The only other part that may be a bit “weird” is the boot0/boot1 disks, but those aren’t even read in in the case of resizable images.

[george1421]

@Tom-Elliott From what it sounds like something is not allowing the fog client OS to boot. One thought was that it couldn’t enumerate the disks or something similar, but that is only a very uneducated guess.

[Tom Elliott]

@george1421 I understand, I was just giving information pertinent to your prior posting.

Though I will have to add, mmc disks are actually working, so if it’s stuck on the disk it would be a bit odd. From the sounds of it, it’s either stuck (meaning maybe just taking longer to load – I’m guessing you’ve waited more the 2-5 minutes with the same results?), or impatience.

[Wayne Workman]

I suppose the simple things have been checked, for instance removing any extra storage devices like SD cards and MicroSD cards ?

[Matthieu Jacquart]

@Wayne-Workman Yes, there’s just internal SSD and RJ45 adapteur
@Tom-Elliott I’ve been waiting much more than 5 minutes, around 1 hour, and still nothing…

Something interesting, I have some error message when I choose boot from hard disk or memtest86 :

Just testing with last svn / kernel 4.4, same trouble

[george1421]

@Matthieu-Jacquart If you are willing and have a general knowledge of linux, I would like you to try something.

I’ve been working on an idea about booting the FOG Client kernel (the bits of FOG code that run on the target computer to load or capture images) using a usb drive. Understand this is only for debugging purposes. Right now it is not clear in my mind if the booting issues with these newer efi based systems are with the PXE boot kernel, the FOG Client kernel, or the hand off between ipxe and the FOG kernel.

To test this I wrote a document to create a uefi boot media that will boot the fog kernel from USB. You can not capture or deploy using this kernel only access command line tools. But the point of this exercise is to see if it boots, period.

If you have a spare 2GB or larger usb flash drive, are comfortable with some linux commands and have a little time; could you follow the instructions outlined here: https://forums.fogproject.org/topic/6532/usb-boot-target-device-into-fog-debug-os/3

For the sake of the test, I only want you to execute what appears id method #3. Understand these instructions were written for ubuntu, but they should translate to debian without issue ( ) . At the bottom there is a copy and paste section where you can copy the commands paste them into a text editor, change the reference to the usb flash drive and then just execute the commands one after another through a remote terminal. It takes me less and 5 minutes to execute the commands once you have the apt-get files installed.

For the flash drive start with a freshly formatted flash drive using a windows computer and format it fat32 (note the first step of my instructions tells linux to reformat the drive, any existing content will be lost). If you have any questions about this, please post back here.

What I want to test:

1. Does it boot?
2. IF it doesn’t boot is there an error message?
3. Does this image boot on any other device you have that is in uefi mode?

After this test we will add in the grub insmod commands and test again. But first lets see if you can build the boot drive and get it to boot on this table as is.

[Matthieu Jacquart]

@george1421 ok, Here’s the result… I don’t know what to do with that

[Tom Elliott]

@Matthieu-Jacquart I need more information. You’re having issues getting fog to boot ON the hybrid, or you’re having issues with iPXE passing the information back to the tablet to allow booting to the actual Hard Drive?
