Can't get to FOG booting from USB Boot UEFI client

[Fog_Newb]

Hi,

I followed the instructions here and created a USB Boot UEFI client.

https://forums.fogproject.org/topic/6350/usb-boot-uefi-client-into-fog-menu-easy-way/12

I disabled secure boot and enabled booting from anything. And I can boot from the USB drive, it starts to ipxe boot but then my display goes out, then a mac OS error screen really quick then it boots from the mac OS SSD.

I have a 2018 Mac Mini, I manually added the host to FOG, blah blah and added the t2kernel and specified in the settings for it to use that kernel but I don’t think it is getting that far. I am using the built in Ethernet on the mini.

Is there an updated guide for pxe booting t2 intel based macs?

@fog_newb It starts the ipxe and stops where exactly? Configuring Devices?

Not sure. I don’t think it gets that far but it is hard to tell. It boots from bootx64.efi (the renamed ipxe.efi) on the USB something, maybe the banner appears or whatever text when ipxe.efi loads, then the screen goes black really quick - as it reboots. I can try to take a video of what happens.

I thought about making a USB stick with an EFI partition and putting the bootx64.efi on there but not sure if it would make any difference.

@fog_newb I don’t think iPXE is compatible with the newer macs (if they have the T2 chip in them). You might have to boot straight into FOS linux and bypass the iPXE step. It would be interesting to know if the 5.15.x series of linux kernels support the T2 macs natively or does the kernel still need to be patched. I did create a one off T2 kernel a while ago that worked. It sounds like you might have found that kernel from your OP.

FOS linux

Is there a tutorial for creating a FOS Linux usb client to work with the pre existing FOG server?

@fog_newb Yes there is: https://forums.fogproject.org/topic/7727/building-usb-booting-fos-image

Also look at the FOG Forum chat for a few hints on how to get started.

@george1421 Awesome - this worked. It booted from the stick fine and I was able to perform a quick registration. I started to capture the drive and it worked up until it came to the APFS portion. I ran into the apfsclone.c: bitmap error, like with the hackintosh.
