Samsung N140 JA05IT AHCI

[Ranmamez]

Hello.
I know that this is a very very old netbook but the proprietary asked me to get the most of it, since she's affectionated to it.
So I found that there was installed an SSD but the BIOS doesn't have any AHCI option switch.
I already tried to install the latest available (05CU), to no avail.

Here is the link to the original bios updater: https://org.downloadcenter.samsung.com/downloadfile/ContentsFile.aspx?CDSite=UNI_IT&OriginYN=N&ModelType=N&ModelName=NP-N140-JA05IT&CttFileID=2388961&CDCttType=FM&VPath=FM%2F201001%2F20100115101842296%2FWIN_N140_05CU.exe

Is it possible at least to unlock the AHCI switch?
Thanks.
