@Florent Thanks Florent. Hopefully it does!
The issues I’ve listed here do seem to only affect older models of Dell, however UEFI (despite having the word unified in the name) varies wildly by vendor, and even within Vendors, so I wouldn’t be surprised to learn there are similar or different issues affecting newer Dells or even non-Dell machines.
That said, based on my experience at work. I can’t say I’ve seen too many machines have the number of bizarre issues as I have seen with the older Dell PCs we have.
As with all things, I’d suggest testing it on some of the machines common in your fleet of computers and seeing what works and what doesn’t.
