Tablet PC hangs on bzImage
-
Capture and deploy completed successfully! Looks like the problem is solved. Thanks for all your help, guys!

Wow, we finally made it. So to make a long story short, it was simply compiling a special iPXE binary that has a native AXIS driver included. Keep in mind that other USB devices are being disabled through this.
As well note George’s advice on the inits.
I am Wanderung if we should add this special AXIS iPXE binary to our repo and installer?

@Zerpie Ok I don’t know what happened in the last couple weeks, but it’s not working anymore. I’m back to getting the following errors when trying to capture an image from these tablets.
bzImage32... ok Could not select: Exec format error (http://ipxe.org/2e008081) Could not boot: Exec format error (http://ipxe.org/2e008081) Could not boot: Exec format error (http://ipxe.org/2e008081)I haven’t made any changes to Fog since I got this working originally. I told my team that it was working and they could move forward with using Fog to image these tablets. Once they got around to it they brought it to my attention that it wasn’t working.
I also don’t know if I need to start a new thread since I already marked this one as solved.

@Zerpie Remember this tablet seems to disguise it’s architecture being 32 or 64 bit. In the process of trying to make this work we renamed kernels and inits and also set those parameters in the host’s settings.
Probably best if you reset kernels an inits to the latest and then check the host’s settings again.
sudo -i cd /var/www/fog/service/ipxe mkdir backup mv bzImage* backup/ wget https://fogproject.org/kernels/bzImage wget https://fogproject.org/kernels/bzImage32 mv init* backup/ wget https://fogproject.org/inits/init.xz wget https://fogproject.org/inits/init_32.xzNot go to the tablet’s host’s settings in the web UI and make sure you have Host Kernel set to
bzImage32and Host Init set toinit_32.xz. -
@Sebastian-Roth The first thing I checked was that I had Host Kernel set to bzImage32 and Host Init set to init_32.xz since that was the last thing we were missing when we got it working last.
I followed your instructions of moving the original files and getting the latest ones, but I’m still getting the same Exec format error.
-
@Zerpie Are you surely using the exact same physical tablet device this time? Maybe it’s just another one, same model but different firmware version or BIOS settings?
What happens if you set back to bzImage/init.xz in the host’s settings? Same exec error?
To me it sounds as if secure boot is enabled on the tablet.
-
@Sebastian-Roth It’s the same model, but not the exact same tablet I got working before.
I tried changing the host settings back to bzimage and init.xz and I got the same error.
These tablets do not have the option to enable/disable secure boot in BIOS setup.
I’ll see if we still have the original tablet that we got working to see if it’s also getting the errors.
EDIT: Nope. It’s impossible to find the original tablet. It was added back to the stock of all the others and I didn’t get the serial# from it.
-
Ok I don’t know what happened, but after I exited BIOS settings this time on the tablet, it booted into Fog and started a capture task. I have no idea why. I didn’t change any of the settings. I’ll have to play with it some more.
-
@Zerpie Oh dear, doesn’t sound like reliable devices you have there. Hope you figure out how to handle those and make them work properly. Doesn’t sound like this is something we can handle with FOG. But keep us posted on how you go.
-
@Sebastian-Roth Yeah I was thinking the same thing. So now that tablet is booting reliably every time. I’ve moved to another one and it’s getting the errors again. This is totally a tablet-related issue and not a Fog related one.
