Thanks for the reply guys. I forgot to mention that the device either boots from a specific M2 drive (have tried other M2 drives and nothing), and if the drive is not present then it boots from the network. I already pxe booted winpe and some and some live linux distros in order to run the tools to attempt to resolve the firmware thing.

I was under the impression that though iscsi may not be a go, I could achieve the same result using an NFS share, I believe I saw some mentions of that in some of the threads that came up during my searches.

Independent of truenas I would like to get a nice setup going, though I have another vm running bareos for backups, FOG seems really convenient for backups, booting into diags, etc. In any case, I’ll read up on those 2 links and head over to the ipxe wiki to see if I can pick something up. Thanks again guys.

Hey everyone,
I would like to boot a physical truenas machine diskless. FOG is installed on a VM in my proxmox server and it works, but I’m not sure how to go about creating an entry for this. I’m rather new to creating a network booting environment, so you’ll have to excuse me for missing anything super obvious here. For what I read I should be able to go either with iscsi or nfs.

Some background on why I want to do this, I managed to grab a Verint NVR that had one network port busted, but otherwise works perfectly fine, only thing is that the BIOS/UEFI is locked behind a password which I don’t have access to, and I tried everything I could find info on to get/crack/remove the password, but no cigar. The kit would be a small upgrade to my current one hardware wise, if I could just fit my current board in the case without having to take a dremel to it, I maybe would have gone that route. At the end of the day, I’m using this as a reason to get better aquainted with ipxe, so if anyone has any suggestions I would appreciate it.
