the downgrade 0068-->0066 works but does not solve any problem (=with SSD connected I'm unable to access the BIOS or to start the OS). Further downgrades from 0066 are not working.
Is there any intel staff available with a brilliant idea?
thanks for your answer. I wrote you a private message.
@ Intel staff:
Please withdraw the BIOS update on the following pages:
As you can see here there are some others who are having problems with Samsung SSD 840/850/860 with this BIOS. I am sure that this is a bug.
I really hope that you can fix this bug soon.
Thanks and kind regards
I've tried with a Kingston SSD A400 120GB and it gets recognized by the 0068 BIOS.
It seems to me that the problem might be related to the SAMSUNG SSD EVO drives.
Nevertheless the BIOS 0062 did original work with the SAMSUNG SSD EVO 840 120GB.
For information: I did try a BIOS recovery to 0062 according to:
BIOS Recovery Update Instructions for Intel® NUC (BIOS Recovery by the Security Jumper)
but it did not work.
I hope Intel staff will look into the matter asap.
Thank you for your response and the information provided, we are going to look investigate the situation we will be posting back as soon as news become available.
You can't downgrade to any BIOS prior to 0066 due to security updates.
One question I have is have all the people who are having issues with 840/850 EVO drives, have you updated to the latest firmware for the SSDs? As for the PM851 drive, this is an OEM version of the Samsung EVO drive provided to OEM system builders like Dell, Lenovo, HP. This drive may not be supported correctly due to special firmware provided for those OEMs. If you took the drive out of an older system, you might check with the OEm to see if any updates are available.
Here is a link to Dell's FW update for their PM851 drive:
thank you for your answer. I haven't tested if a downgrade of BIOS would be possible, but if you say that it isn't, I don't need to try it by myself.
My three Samsung SSD 850 EVO have the latest firmware already installed: EMT02B6Q. I installed it some weeks ago with Samsung Magician.https://s3.ap-northeast-2.amazonaws.com/global.semi.static/Samsung_SSD_850_EVO_EMT02B6Q_Win.iso
It is also correct that the Samsung PM851 is an OEM drive. My PM851 is from a Fujitsu notebook, in which I put an Samsung SSD 850 PRO because I needed TCG OPAL drive encryption.
The firmware on my PM851 is EXT0200Q. From Fujitsu there is no firmware update available and the updates from DELL or Lenovo can't be installed on this SSD.
I think I will contact the Fujitsu support and ask for a firmware update, but at the moment I would no install it until Intel has a solution for the problem that BIOS since version 0066 does not accept Samsung 840/850/860 SSDs.
same problem here. Just upgraded my NUC 5PPYH with SAMSUNG 850 EVO from BIOS 64 to 68.
Please, make an alert on BIOS download page as soon as possible: Samsung 850 SSD is very popular!
I succesfully downgraded to BIOS 66 removing the SSD, but it has the same problem of version 68.
Is there a way to force BIOS downgrade to 64?
