    Ciao Micka,
    have you sent this to Ettore too? This is precious information for us to know.

    I found that the first few boots after the BIOS upgrade took MUCH longer than expected (so much so that I initially thought I may have had a bricked system). I reported this back as something that users should be made aware of. However the boot time has now returned to normal so in that sense all is good. I probably have also done a power off since the upgrade - not sure if that is relevant as well in getting boot times back to normal.

    Same here. BIOS 1.05 RC13. After initial post-flash reboot, post is super slow, even entering BIOS and navigating BIOS menus took extraordinary long time. Could be due to fact that Embedded Controller as well as USB-C susbsystem is also updated. Only after a "Restore Defaults" & "Save Changes" from BIOS menu, followed by full power cycle things went back to "normal".

    @itimpi are you also on 1.05 RC13?

    Yes.

    I also have the ‘v’ variant of the fan (one with the green dot) so I wonder if this was why I saw no obvious reduction in fan noise from this version of the BIOS? Currently running with a Gelid Silent 6 fan which is either on or off, but since I cannot hear it when on unless I put my ear just a few inches from the Bolt this effectively solves the noise issue for me.

    I highly suspect so. If you check history.txt supplied with BIOS update files, there are several mentions of "bad" FANs. I strongly believe that H05BIV aka "green dot" fan variant is the very example of this "bad" FAN, that is physically incapable of being RPM controled when connected to Udoo Bolt Embedded Controller, which makes BIOS PWM control settings useless. Bolt's controller can only turn H05BIV on and off.

    Please could someone who received the new Beta BIOS do me a favor and post the output of
    dmesg | grep -i TPM
    under Linux?
    Currrently (BIOS version 1.05 RC8) the tpm doesn't work on my my board: the output of the above command is:
    [ 0.000000] efi: TPMFinalLog=0x9dcdf000 ACPI 2.0=0x9db9e000 ACPI=0x9db9e000 SMBIOS=0x9e3a2000 SMBIOS 3.0=0x9e3a1000 MEMATTR=0x9a160018 ESRT=0x9bbba818
    [ 0.005172] ACPI: TPM2 0x000000009DBB9B00 000034 (v04 ALASKA A M I 00000001 AMI 00000000)

    [ 0.494982] ima: No TPM chip found, activating TPM-bypass!

    Thanks in advance!

    @Ratz Fatz As you can see, same here. I'd blame this totally on BIOS, as when I tried messing up with some TPM settings in BIOS, TPM disappeared altogether despite BIOS being set to "Enabled" (BIOS all other TPM options disappeared as well, only full "Load BIOS Defaults" made them come back)!

    Sad to hear that. So the TPM is completely unusable under linux, even with the latest Beta BIOS. I was planning to play around with secure boot and disk encryption with keys stored in the tpm (bitlocker-like).
    Shouldn't we open a separate thread for the TPM topic?

    What did you use as an adapter or did you put a custom cable together?

    The 1.06 Bios does not seem to help the fan noise. It almost wouldn't be as bad if it was on all the time, but the cycling on and off makes it mopre noticable.

    Can you elaborate on how you went about mounting and connecting this fan. I purchased one because I was committed to making this thing quieter and I have one of the green dot fans. The springs on the screws that came with the stock fan don't exactly fit the gelid though and the connection on the fan is is different (I think the stock fan connection is micro JST?). I could probably figure out some ghetto solution, but I'm interested to hear how you did it in the hope that you have a more elegant solution.

    The 1.06R4 update killed my V8. The HDMI output became an epilepsy-inducing flashing mess, and it freezes on the UDOO BOLT logo (+20 mins tested). See the joined screenshot.

    Specs :
    UDOO BOLT V8
    16 (8x2) GB 2400MHz DDR4
    No SATA/PCI-E device installed

    Bios updated on Ubuntu 18.04 using the tool in the archive, no errors during the flashing process. I tried resetting the BIOS settings, to no avail. The fan seems to work fine (though no improvement in noise)

    You can buy short 6” leads with the Bolt board connector already fitted (I got 5 for £2.50 on eBay) and I soldered one of these in place of the connector on the Gelid.

    Makes sense, what about the screws/springs needed to mount the fan on the heatsink?

    . I just used the ones provided (although I turned the springs upside down).
