@george1421 said in DELL OptiPlex 7000 can’t disable UEFI. Help for FOG neophyte?:

If you have an unchangeable dhcp server and your target computers are on the same IP subnet as your FOG server you can install dnsmasq on your fog server to override dhcp options 66 and 67 with the proper values.

Thanks for your helpful response! I appreciate it!

The target computers are all on the same IP subnet. One of our parent company admins suggested that I look into dnsmasq (after I sent him a link to your response on this thread). My initial response to him is this:

I’m sure I could get dnsmasq installed, but whether or not I’d end up doing something stupid that conflicts with your DNS/DHCP servers is debatable.

If I install dnsmasq on the Ubuntu 20.04.6 LTS server, with dnsmasq using its default “hello world” settings, is there danger of it conflicting with the DNS and DHCP server services that already exist on our network? I want to be particularly responsible in that regard. Our parent company admins manage a huge network and the last thing I want to do is to become a thorn in their side.

My background is in Microsoft MSSQL administration. Linux server networking is something that makes me nervous.

Hello All,

I inherited a FOG 1.5.10 server (Ubuntu 20.04.6 LTS) at work about two weeks ago (upon my return from vacation). I had never heard of FOG until then. The server had been setup while I was on vacation by a guy whose last days working here were during my vacation. Here it is… it’s mine.

The new PC’s we have here are DELL OptiPlex 7000’s that cannot disable UEFI. I have read around the different posts for similar issues and I’m afraid that the newbie in me is a bit overwhelmed.

Additionally, the large organization I work for is like an island working inside of a MUCH larger organization. We do not control our own DHCP server, and need to wade through bureaucracy to get anything done. My predecessor managed to get the DHCP server updated to let me PXE boot with FOG. I have a couple of images setup and it works great on the older machines I was testing with!

Here is a link to information that DELL had about PXE booting these new machines. They don’t actually mention FOG in particular… just PXE.

Can anyone look at this and give me some advice as to if FOG is going to be the best choice for something like these machines? I did forward the DELL link to our liason with the parent organization and hope to hear something useful from them as well.
