Linux Flavor locked at incompatible version and can't be upgraded to another version
Years ago we made the mistake of buying a Precision Desktop machine with Ubunto Linux. We have an old piece of software that runs an Nuclear Magnetic Resonance (NMR) system which required an older version of Linux. Unfortunately after many futile attempts, we were unable to install the softqqware because the OS was locked at the factory into the newer version of linux. Because we have had extemely good luck with Precison T3500 boxes with all of them, purchased ca 2012, continuing to run RHEL 6.0 , we are ntertaining buying another, maybe more of the newer Precision versions of Precisions. The one I bought in ~ 2019 with ubuntu locked in was relegated to a data backup workstation and we continued to use old the T3500 box for that workstation to this day.
My questions are, can Precision workstations be acquired without the OS locked in from the factory? How do I order them without an OS or with an OS that is upgradable to another Linux version that we can use with our older NMR software?
Thanks,
Robert

Hi
I don't really understand the question, although I did understand enough to pose it on the internet and..........
Yes — Dell Precision workstations can be bought without a factory OS, and Dell also sells some Precision models with Linux preinstalled rather than Windows. For older machines like the Precision T3500, Dell’s own support page shows the model has a defined list of supported operating systems, but anything outside that list is not officially supported by Dell.
What that means for a T3500
The Precision T3500 is an older workstation, so in practice you would normally buy it used, refurbished, or as excess stock, and then install your own OS yourself. Dell’s T3500 technical guide shows factory offerings that included Windows, Red Hat Enterprise Linux 5.3 64-bit, and FreeDOS, which confirms that an OS-free or Linux-capable factory setup existed for that platform. For current Dell Precision systems, Dell’s N-series/workstation guidance says some workstations ship with no OS preinstalled, and select Precision systems can be ordered with Ubuntu or Red Hat Enterprise Linux instead of Windows.
How to order
On current Dell Precision systems, the usual method is to go through “Customize & Buy” and choose the operating system during configuration; Dell and Canonical both describe Linux as a selectable option on supported Precision models. If you want a machine with no OS, look specifically for Dell’s no-OS or N-series configuration on the relevant product page, or ask Dell sales for a bare system or FreeDOS build where available. For older T3500-class systems bought second-hand, the practical route is to choose a unit advertised as “no OS,” “FreeDOS,” or “blank drive,” then install Linux yourself.
For older NMR software
If your older NMR software needs a specific Linux version, the safest approach is usually to buy a workstation with no OS or with a Linux distro that can still be upgraded in a controlled way, then validate the software against the exact kernel and library stack before deployment. Dell’s current support model for Linux on Precision systems is tied to select Ubuntu and RHEL versions, so if you need an older or niche Linux release, Dell support may not cover that configuration even if the hardware runs it. In that case, it is often better to treat Dell’s OS as the starting point and manage the software environment yourself, including freezing packages or using compatibility containers if your NMR vendor allows it.
