Disable UEFI in CM8i7CB Compute Element with BIOS 0092

[romerord]

Recently purchased a NUC8 CM8i7CB Compute Element and installed into a CMCR1ABA Rugged Chassis. Installed dual Samsung EVO 970 SSDs, 250 GB & 2 TB. Once assembled I updated the BIOS to 0092, doesn't appear to be Visual BIOS.

Due to the customized Linux OS I intended to install, I need to switch to Legacy Boot versus UEFI. I have already disabled Secure Boot. UEFI still shows enabled. SATA mode only gives me the option of AHCI. I don't see an option available under Power for Sleep Type support: Legacy S3 Standby or Modern Standby.

Any suggestions?

AFAIK, the NUC Compute Elements do not support Legacy Boot.

Every Linux distribution supports UEFI boot. It is time for you to make the transition. The future is here.

Just saying,

Scott,

Thank you for your insight. Unfortunately I'm dealing with a commercial product which is based on a legacy Linux distro, so I have zero control of forcing them to update to a more modern distro.

I'm trying to see if I can create a UEFI bootable usb stick with the image file which comes from that product, *.img.gz

Hello romerord,  

Thank you for posting on the Intel® communities.   

I would like to let you know that your unit only supports Ubuntu 18.04 (LTS), as you can see on the following link (your unit shows as CM8i7VB):

- https://www.intel.com/content/www/us/en/support/articles/000055730/intel-nuc/intel-nuc-elements.html

My recommendation would be to check with your Linux distributor to confirm that the current version that your trying to install is compatible and supported for this unit, also to get the right version/drivers and steps to install it.

Regards,

Hello @romerord

We confirm that the legacy boot option is not supported on this model. For more information you can check the article: Intel® NUC Products Phasing Out Legacy BIOS Support

if you intent on using an Linux version different than Ubuntu 18.04 (LTS), the best option is to check with the Linux distro for more information. If you need any additional information, please submit a new question as this thread will no longer be monitored.
