Hello All,

Please guys, help me in unlocking Samsung NP500P4C BIOS?

I want to unlock/unhide the advance tab.

My current BIOS version is P08RAB.

I have attached two backup files, one was backed up by the Universal BIOS Backup ToolKit 2.0m and the other using WinFlash.

Thanks in advance.

Hello everyone, 

Recently I bought a Samsung 850 EVO SSD and I was wondering if my board could support Sata GenIII.
After some research, I found that there is a hidden option in BIOS that enables this option.

My Computer is a NP500P4C-AD3BR (Cheers from Brazil)
And my Phoenix UEFI Bios Version is: P08RAB

If anyone in this forum could help me patching the BIOS or giving me at least some direction I would be very happy    .

Files included in the ZIP:

- Folder with Bios Update Files (captured from %appdata%/Local/Temp) (Probably won't useful  )
- BIOS.BIN (dumped directly from DOS FTP)
- IFR info (extracted using UEFITool and IFR Extractor)

Thanks,
Matheus

Ps: Sorry for my bad english.
Ps²: Setting configuration via setup_var gives me 'offset out of range'

Thank you so much, but when I try to flash the BIOS I get

Error 28: Protected Range Registers are currently set by BIOS, preventing flash access. 

Secure Boot is disabled.

Secure Boot is disabled.

Your bios chip is rewrite protected
Bios mod can be flashed using SPI-programmer+SOIC8 clip only

Thanks! 

If I succeed I will post the results.
