That’s weird. Your BIOS has exactly same AHCI and SATA modules as mine Yepo 737A YEPOM10x.WP313R.NHNAUHL01.rom, which almost never detects my Kingspec NT-256 (same-model-other-capacity, I think) drive. So BIOS recognition issue must be caused by an inherent hardware flaw of P313R motherboard, that has been fixed in P3132 motherboard which, I believe, your Jumper has inside.

Still, there is a small chance that P313R’s SSD recognition problem is caused by some other faulty BIOS module(s).

I don’t know what jumper version are working OK with SSD but it could be a good idea to do some statistics on that particular point.

That’s weird. In this comment user says that he has no problem with BIOS recognition of Kingspec NT-128 with 12/05/2018 BIOS on EZBook 3pro. This BIOS has exactly same AHCI and SATA modules as mine Yepo 737A YEPOM10x.WP313R.NHNAUHL01.rom, which almost never detects my Kingspec NT-256 (same-model-other-capacity, I think) drive.

Still, there is a small chance that issue is caused by some other module(s).

If it works then I’ll try to change ahci bios module with the one from Ezbook 3L

Any luck with that?

1. Yepo 737A
2. “emobilehome” from Ebay
3. 2018, March
4. Windows 10 Home 1709 16299.431, still at EMMC
5. YEPOM10x.WP313R.NHNAUHL01 (10/09/2017), also tried YEPO10x.WP313R.NHNAUHL03 (20/09/2017, unlocked), no luck either.
6. Windows was updated.
   
7. Kingspec NT-256

9. Looks like it’s an UEFI issue. There was many disk-related warnings in Windows system log, until I installed “New Universal 64bit Intel RST AHCI & RAID driver v13.44.0.1026 mod+signed by Fernando“. But SSD almost never appears in UEFI Settings. Even if – after some restarts – SSD got detected by UEFI (displayed as “NT-256” at SATA pane and Security pane), UEFI shell shows buggy behavior. I tried to run “ls fsN:” command repeatedly, and got ~70% errors, like “Device Error”, truncated listings etc., and only ~30% full correct listings from it. Also tried to boot Fedora 28 “rescue mode” from USB stick and SSD seems to work nice. So everything looks fine when you boot OS with correct AHCI drivers from USB or EMMC (didn’t test it for long time though), but the UEFI is unable to work with SSD smoothly.
