[REQUEST] Probook 450 G2 BIOS Unlock
#1
Hi all,
i need to unlock features for my bios:
Inside H20 Bios F13(here are the files)
https://mega.nz/#!YJl3QLqb
there is the key: bGV9QK3VUZ8VuWPVWycPLStkd24cHpDPkR9Wd8Vpza8

Here is the link 
This is my laptop


HP Probook 450 G2
i7 5500U 2.4 Ghz/Mobo:HP 803b(Clover)
AMD Radeon R5 M200 Series/Intel hd 5500 
graphics/ScreenResolution:1366x768

memory:4 gb of ram ddr3 kingston



i am on trying to change the DVMT graphics memory but it keeps telling me this fail u can see on image, the program i used is phoenixtool
someone has a idea how can i read the bios files or someone that can unlock the bios.

Reading a little i founded how to get the .rom for my Bios, just simply making a backup with the universal backup program and i did finally read the structure of it and here is the the bios .rom file:
.rar   Insyde-F.13.rar (Size: 2.99 MB / Downloads: 13) i think with that file is easy to unlock if someone can

Hello,
I have a HP Probook 450 G2 on which I'm trying to add 32GB m.2 ssd as a hdd cache using intel rapid storage / intel smart response. In order to activate hdd cache sata mode needs to be changed in bios from AHCI to RAID before caching option becomes available in Intel Rapid Storage Application. My problem is that the only option available in bios is AHCI (no IDE or RAID listed there).
It is possible to modify bios to make RAID option available in BIOS?

BIOS Version/Date Hewlett-Packard M74 Ver. 01.49, 7/30/2018 
SMBIOS Version 2.7 
Embedded Controller Version 103.37 
BIOS Mode UEFI 
BaseBoard Manufacturer Hewlett-Packard 
BaseBoard Model Not Available

Using UefiTool and Universal IFR Extractor I have decoded the PlatformSetup and I found:

0x14115 End of Options {29 02}
0x14117 End If {29 02}
0x14119 End If {29 02}

so RAID option is suppressed in bios.

Any hint on how to enable this option and how to flash back the modified bios will be very appreciated (I work in IT field but I have no experience with modifying bios.). 

Link to the bios:ftp://ftp.hp.com/pub/softpaq/sp91001-91500/sp91475.exe
I also have attached an RWeverything acpi tables report for my system.


Thanks.
