Thanks Genius,

I'd love to try it, but have you tried it before and did it work?

Can you confirm it'll also enable IMEI?

I've got an eglobal Xeon E-2176M , any idea if this BIOS will work? If yes, is there any guide on how to flash it?

Thanks, Sub.

Hi, I asked the Aliexpress seller of mine for an unlocked BIOS Update and they provided a new version from October but unfortunately it's still completely locked down.

Here's the download: https://mega.nz/#!t5QFjagb!pjzElejgwIFO3...RvpxrWG8Vs

Has anyone had success with the unlock? I'd really like to tweak the fan a little bit as it seems to have a lot of headroom.

In case you are using Linux, is the PM, sleep/suspend fixed? On EGlobal S200 Xeon E-2176M it is working under Windows but on Linux the system cannot be suspended.

no, I'm using macOS. The system can be suspended, but always freezes a few seconds after waking up. I've read somewhere that it is because the Intel Management Engine (IMEI) is missing/not configured in the BIOS. I guess the manufacturer didn't pay the license to Intel and therefore couldn't enable it.

The supplied Windows driver allow the sleep states under that OS and the system can be suspended/resumed without any issue. Thus is either a software workaround of the IMEI or a broken DSDT/ACPi table? I contacted the eGlobal support...

After a couple of days in which I couldn't get in touch with an engineer, the support representative said "the sleep problem for LINUX, cannot solve it".

Yup this is correct. I'm using macOS too. My understanding is that the only way IMEI can be enabled is by restoring the ME region in the BIOS either with some fancy hacking or by getting a BIOS update from the OEM with the ME region enabled/intact.

Let me know if there are other alternatives.

Hello genius239 I need your support about unlocking functions of newest BIOS for Hystou S200 (equal to EGlobal S200) that I have, because it is not possible to overwrite my existing BIOS version with unlocked version 06 that was post in previous posts. I need to unlock TPM 2.0 function, because at this moment I can only enable Secure Boot for UEFI, but missing option to be enabled TPM function of Intel 8-th Generation processor (Intel i5 8300H) installed in this mini PC system (TPM Device selection - PTT / PCH-FW Configuration - menus missing in advanced tab). I hope to be possible for you to assist me with unlocking of BIOS functions for optimal using of mini system.

You are great! Thank you for support and fully unlocking of this BIOS version for Hystou S200.
Unfortunately this MB maybe not support TPM enabling, because I can see and change function, but after restart aways return to dTPM and can not store set PTT enabling and state not change.
Thank you once again for your help and assistance.

@Rub4o

In addition to the "TPM Device Selection" to PTT ,please also go into Advanced => Trusted Computing => Security Device Support ,then set it enable. Then gonna test tpm again.
