Hello, I would like to get an updated BIOS for my Corebox 256G21072757. It seems that PXE boot is not working, I think an update could help.  
Here is a picture of my current BIOS, as well as the “network” parameter in boot1

Because you have network as the first boot option ?

To update the BIOS, you must have the exact file for your model.  
You can ask support.

Thank you for your reply. I’ve submitted a support request for the update.

Otherwise, is it normal for PXE boot not to work on this device?

Hello, support tells me there’s no other BIOS for my Corebox.  
I’d just like to know why PXE isn’t working. Is this normal?

Can you show a photo of the Advanced bios screen?
