[Help] Samsung NP535 BIOS Unlock
#1
Hi, people! I have Samsung NP535 laptop with AMI Aptio 4 UEFI BIOS. And I have several problems:

1. Like in this thread, AmiBCP is useless... The same problem: changes not saving.
2. SATA-III mode is locked in BIOS.
3. UEFI mode is not working. I can't boot in UEFI mode: looks like it's disabled... But I enabled it in BIOS.

Can anyone inspect? I will attach my BIOS dump.

If my mod can unlock extra tab Advanced、Chipset and Boot ,please capture screen of them.

You wanna uefi boot ,can going to new boot tab>>CSM parameters sub menu to adjust.
It also has a option "CSM Support" on boot tab.

Yes, my chipset supports SATAIII, but it's disabled in BIOS. Sad

But really I disappointed that there are no SATA-III mode menu at all Sad I know, that my chipset is supporting it.

YES! It is working on 6 Gb/sec! The last one required step: there is a "Main" tab, which is actually still hidden. I changed parameters of highlighted fields as shown, flashed and got SATA-III. But w/o your BIOS it wasn't working.

My test2 bios already change these two option "Sata 6 AHCI Support" and "SATA MAXGEN2 CAP OPTION" , i spent some time to google information ,so i know these two option can get sata3 speed.
I know it on a MSI laptop forum.

Test my test3.
