Unlock AMI Aptio Toshiba P50-A-127

[topaj]

Hello,

I want to unlock AHCI features for my AMI Aptio bios.
Here's a link to the extracted UBIOS folder that the automatic installer created:

Link to original update package:

(Version update already applied, so I'm using the newest update right now)

I tried myself to extract winflash.exe, and found a bin file of 4100kb. When I openen the file in AMIBcp, it only shows 1 tab with bios version file. I'm stuck, so I would really appreciate your help.
