We’re running into an issue now that we’re getting devices with no Legacy BIOS support. We have to switch the bootfile on the DHCP server almost every time we image a device.

I did some research, and saw that there’s some documentation for this exact issue:
https://wiki.fogproject.org/wiki/index.php/BIOS_and_UEFI_Co-Existence

The Problem is we use our SonicWall for DHCP, and there’s nothing listed in there about configuring this on a SonicWall.

Any help or even suggestions is appreciated. I’ve looked into this for quite a while, with no success.

There is another way too, If you have a generic USB2 ethernet adapter we can pxe boot using a usb stick and let iPXE or FOS Linux manage the network drivers.

Can you please elaborate on this? I’m having a tough time understanding what you mean by that. I’d use a USB 2 ethernet adapter, then also use a USB stick?

@sebastian-roth We tried plugging in a StarTech USB->Ethernet adapter, but we just couldn’t get it to show up in the boot menu. Confirmed USB boot and PXE boot were enabled in the BIOS, but we still weren’t able to get it to show up in the boot menu. The model of laptop I was testing was a HP EliteBook 850 G7. We sell a lot of G7 HP devices, and we just noticed this issue now.

The only options that show up are IPv6 and IPv4 WiFi PXE boot, which I don’t have any experience with. I figured I’d ask here to see if anyone has any ideas or suggestions.

We’re running into an issue with some newer laptop models that don’t have legacy support, where we can’t find a way to PXE boot. There’s no ethernet port on the devices, so we’ve been trying USB->Ethernet adapters with no luck. Is there a way to set FOG up for WiFi PXE booting? Or is there another way to make this work?

Any suggestions are appreciated, I’m guessing I’m not the only one with this issue.
