@Lost_N_BIOS
I made a big discovery of Optiplex 990.
I had upgraded the latest bios released in 2018.There is no need to dump or flash by SPI programmer.You just need to short the Service Mode jumper,then you could dump the full bios and flash the modded bios directly by FPT.
But It's a little regrettable.I added the nvme module in this mobo,but there was no "pata" or "windows boot manager" could show when plugged in the NVME SSD which has been setuped win10.

@RatchetRussian - sorry I missed your post until now! What do you want to do?

Please don't send PM's for help on BIOS edits, I can't help with BIOS in PM's. Please make a thread and I will try to help as soon as I can - thanks!
If you appreciate my efforts and are willing to donate to help improve my hardware, gift cards work for me (Amazn, NuEgg, eBa) - send me a PM
I view the forum like this, please bump your thread 1x every 24-48 hours if no reply

Did you guys ever get this sorted? Is it possible to enable csm/uefi or to upgrade the version of UEFI? I cannot install CloverUEFI in UEFI mode!

Not always possible on some Dell systems or it can be difficult to do it.
Search for nvme mod on Dell systems on this forum to get a picture of it.

Donations via PAYPAL / REVOLUT, if u think the guy deserves it, else to the Win-Raid community on the bottom of the page, as it deserves for all the gathered information.
