[REQ]Need to unlock insyde H2O BIOS on my HP LAPTOP

[reubenvarghese1]

Please could someone help me unlock the bios on my laptop -HP 15r 262tu.

This is the link to be the bios- http://support.hp.com/in-en/drivers/self...C11TA930O2

I would be more than glad if i could just enable AHCI in the Laptop so that i could install the mac os x on it.As of now when i check ide controllers list in device manager ,it shows it to be intel SATA ahci controller(which i guess means that RAID is enabled).

PLS HELP cause i badly wanted to enable ahci in the Laptop but i was not aware of the bios in hp.

There is no Bios available for your laptop so probabily is an sp6 or 7 !
Only using an HW SPI PGM We can do this job !

Hi Thanks for the reply
I have an insydeH2O bios .The link is supposed to go to the site with all the software and drivers(including bios) for the laptop.
here is another link -http://ftp.hp.com/pub/softpaq/sp69501-70000/sp69899.exe.This will directly start the download of the bios.

Hello, reubenvarghese1!
I looked in BIOS rom and found hidden option for AHCI.
"Setting: Chipset SATA Mode, Variable: 0x39
Option: IDE, Value: 0x0
Option: AHCI, Value: 0x1 (default)
Option: RAID, Value: 0x2"
As we can see, your Intel Ahci controller can work in 3 modes.Ahci mode is current but if it's wrong please post a screenshot of Main tab Bios Menu.
There are 4 bios in sp69899. I decrypted 0220F.fd and found AHCI settings above.You must discover what is bios of 4 yours.If your Intel controller really works in differ from AHCI-mode you may lose a guarantee for you laptop because modded bios can be flashed only with HW SPI Programmer (ask this request in laptop services)

I too feel AHCI is installed but I needed confirmation from an expert as I don't know how to do what u did and I also know my BIOS is RSA signed so it would have made things a lot tougher if I had to unlock it just for changing SATA mode. .Actually the bios should at least display the sata mode like in most laptops even if they don't give an option to change it but... .Thanks a lot for the info,I will try flashing mac os x

EDIT:i was just tying to learn to extract rom file from bios using cmd(writeromfile command) and that's when it mentioned 0220F.fd and that .exe file is what I have used as my bios so I guess it is indeed in AHCI mode so that gives me a lot of relief .
