Latest BIOS for the AY NUCs is 76 (AY0076). I have attached.

I have most BIO files from release 63 to 76, but not anything as old as 55. I see that it is available in Softpedia - if you trust Softpedia.

Hope this helps,

No Linnux version on Softpedia. Can I safely install latest BIOS update on NUC6CAYS?

There is no OS dependencies in the package. You can use the BIOS' F7 method at boot time to update. If you have a very old BIOS--or you just want to use the safest process possible--I recommend using the Jumper-based BIOS Recovery process to update the BIOS to the latest.

To help you better, here are my step-by-step instructions for BIOS Recovery:

NOTE: Read these instructions completely before starting. Follow all instructions EXACTLY.
On some other Windows-based PC, download the .BIO file for the BIOS release you wish to install.
Insert a 4-32GB or smaller (the smaller the better) flash drive into the PC. It is better (though not required) to use a flash drive that has an access LED that you can watch.
Format this USB flash drive using the Windows Format applet. Specify to install the FAT32 file system (Important: NOT vFAT, NOT exFAT; FAT32 only). You must specify that the Quick Format option be Disabled (unchecked).
NOTE: If FAT32 is not offered as a choice by the Format applet, your flash drive is too big; use another.
Copy the .BIO file into the root folder of this USB flash drive. This should be the only .BIO file in the root folder of this drive.
Properly eject the USB flash drive. Do not just yank it out. Do this from File Explorer or using the Safely Remove Hardware and Eject Media System Tray applet.
Power off the NUC.
Invert the NUC and remove the bottom cover (2.5" SATA Drive bay). Remove the yellow BIOS Configuration jumper from the board. It will be the only yellow jumper; the rest will usually be black.
Plug the USB flash drive into one of the USB ports on the back panel of the NUC.
Power on the system.
The BIOS Recovery process should start automatically. You should see a progress report on your main monitor.
NOTE: If you do not see a progress report displayed on a monitor, do not power off the system for at least 15 minutes. While it is rare, it is possible for the process to proceed without an onscreen display; you must give it ample time to complete, just in case.
When the BIOS Recovery process is complete, you will be asked to power off the system. Do so then.
Restore the yellow BIOS Configuration jumper to the pins it was on previously. This should be across pins 1 and 2 of this (three pin) header. Reinstall the bottom cover and then restore it to normal orientation.
Remove the USB flash drive from the back panel of the NUC.
Power on the NUC.
Immediately begin pressing the F2 key, over and over (approx. once per second) until you see a BIOS Setup (or Visual BIOS) screen displayed.
Verify, using the BIOS version string, that the BIOS installed properly. Stop if it isn't.
Press/Click the F9 key (followed by the Y key) to reset of the BIOS configuration.
Press/Click the F10 key (followed by the Y key) to save the BIOS Configuration and exit BIOS Setup.
Once screen is cleared (goes black), begin pressing the F2 key, over and over, until you see the BIOS Setup screen displayed again
Make any changes to the BIOS configuration that you desire (for example, disabling NUMLOCK) or that you require (for example, setting Boot Order, enabling UEFI, enabling RAID, etc.).
Press/Click the F10 key (followed by the Y key) to save the BIOS Configuration and exit BIOS Setup.
Test.

Hope this helps,
