According to Ubuntu Wiki Dell has discontinued support for Linux. How to upgrade the BIOS then when all of the files are now distributed as a Windows executables?Fortunately, before trying any of not so easily looking solutions on the Ubuntu Wiki I have found out some other way to do it.The “trick” seems to be that you have to use an x86 Win PE OS architecture build, rather than a x64 Win PE flavor. If you already have a working Win PE build and want to confirm (maybe you didn’t build it yourself) just run the following command in your loaded Win PE environment from a command prompt: Sadly, the Dell LTI bootable flash drive I had was running a x64 version.
I used to manage some Dell’s running RHEL and I loved how easy it was to run all the firmware updates released by Dell for RHEL.
I’ve posted a lot of write-ups here on GSD blog regarding custom Win PE disks. If you don’t feel like reviewing all those posts, here are some tools or basic steps in building your own Win PE boot tool: It’s been quite a while since I built a Win PE disk/USB.
The ones I’ve made in the past still keep on loading and working for my off-line system booting needs I really haven’t had a need to update them at all.
I always hoped that there will be some a solution for Debian also.
And the solution exists, and I will exemplify it bellow by updating the bios of a Dell Power Edge SC1435 system.
