\EFI\BOOT
Yep, that worked to get to the menu with the ipxe.efi file. So then what next?
@JJ-Fullmer Also i had not tried your guide yet, i was wondering if there was an option other than that (since it had gotten further) but it seems like that is not the case
-
@K.Hays Whelp, that means that iPXE kernel is OK and it boots into fog’s iPXE menu. So the issue is the hand-off between the onboard PXE rom and the iPXE kernel. In a nutshell this is a firmware issue with the hardware.
So what can you do?
- Confirm that these tablets have the latest firmware installed and test again.
- Contact the vendor and report this firmware bug.
- Decide to move forward with usb booting and imaging that way. The iPXE kernel on the usb flash drive is taking over the responsibility to boot into the FOG kernel, we are just bypassing the faulty uefi firmware.
-
@george1421 So i was able to get to the fog menu with the assistance of the flash drive, but from there anything i try to do with it fails. Also the firmware is up to date.
-
@K.Hays For example if you pick hardware compatibility test what error do you get? Post a clear picture taken with a mobile phone please.
Did you also try to use the ipxe7<something>.efi one?
-
@george1421 more in depth, what happens is: No matter what i click it gets to the point where it says “Init.xs… ok” Then it jumps back to the main fog screen, but plain black background and white text. There is also no highlight showing me what i hover over, and after a while of sitting at that screen it says
http://x.x.x.x/fog/service/ipxe/refind.conf... ok http://x.x.x.x/fog/service/ipxe/refind.efi... ok Could not boot: Error ox7f048283 (http://ipxe.org/7f048283) Could not boot: Error ox7f048283 (http://ipxe.org/7f048283) Chainloading failed. hit 's' for the iPXE shell: reboot in 10 seconds -
@george1421 I did use both pxe files

@K.Hays
Can you try the ipxe7156.efi file in place of ipxe.efi (which you renamed on the flash drive).What you are seeing now is the hand off between iPXE and FOG blowing up just like between the PXE rom and iPXE. -
@K.Hays The refind error is related to when the fog menu exits out after no selection is made. In efi mode it uses refind to locate the boot medium.
-
@george1421 That sounds like no good. What’s available for me to try next?

Well that is disappointing…
OK then we move on to phase 3 usb booting the FOS engine directly. You will loose the tight integration between FOG and FOS but it will work.

-
@K.Hays Now with FOS booting off from the usb drive, you MUST schedule a capture or deploy on the FOG server BEFORE you boot the target computer into FOS. If you don’t you will get a strange message about “type not being defined” or something similar.
-
@george1421 This worked! Thanks a bunch, this is going to cut down maintenance time on these tablets immensely. Also thanks to everyone who took the time to look into this!
The solution was to boot directly to the FOS engine using this guide:
https://forums.fogproject.org/topic/7727/building-usb-booting-fos-image/8It did still take a usb hub, correct Ethernet adapters, and a flash drive but that is perfectly fine.
-
Also as a side not, the only Ethernet to usb adapters that worked were usb 2.0 10/100. Specifically the “Cable Matters USB 2.0 to 10/100 Fast Ethernet Network Adapter” and the “ASUS Network Adapter for Transformer Pad” (model number: 90-XB3900CA00040-). I tried three others that were usb 3.0, gig adapters and they did not work for whatever reason.
-
@K.Hays When booting into FOS this way we only need to ensure that the FOS kernel is updated to support new hardware.
So as the developers release new version of the FOS engine all you need to do is download these files and move them to the previously created usb flash drive into the boot folder replacing the existing files.
https://fogproject.org/inits/init.xz https://fogproject.org/inits/init_32.xz https://fogproject.org/kernels/bzImage https://fogproject.org/kernels/bzImage32In regards to the usb network adapters. When you pxe boot uefi devices you MUST use network adapters recommended by the manufacturer to support pxe booting. When you usb boot into FOS you will have better luck with older USB 2.0 network adapters since those are most likely supported by the linux developers.
