(Request) Samsung NP300E5C Phoenix BIOS unlocking

[Strayder]

Hello,

I want to disable Wi-Fi from BIOS, but it seems that there is no corresponding option in Setup menu. So i need to unlock hidden Setup features.
I've got the following system configuration:

Laptop: Samsung NP-300-E5C A02;
BIOS: Phoenix;
BIOS version: P06RAC;

Firmware may be retrieved using these links:
Official executable: http://www.mediafire.com/?z22reg9ycl41s9z
Backuped .rom (default backup settings): http://www.mediafire.com/?0czq7lth2agmhs6
Another .rom (backup file size extended to 16Mb to ensure that all ROM content is present): http://www.mediafire.com/?y1glb6gh9ijjdde

Any help is appreciated. If BIOS cannot be unlocked for some reason, please just type that it's impossible.
Thanks in advance.
