Unable to disable AHCI mode in HP Pavilion DV7-1245dx

[Randomly]

Well I am having HP Pavilion DV7-1245dx laptop. I wanted to disable AHCI mode in BIOS. Can you tell me any work around to get the same on my laptop. Most of the BIOS options are locked and it cannot be configured at all. So let me know if you are having any idea on the above mentioned issue. Thanks a lot in advance.

I think I got the idea to unhide the option. Well EFI Opcode 0x27 means TRUE so I have replaced the same by using opcode 0X28 which mean False.

FALSE
    One Of [0x36<1>] 'IDE Controller'
    \Help text: 'DISABLED: disables both the PATA & SATA IDE controllers. BOTH: enables both the PATA & SATA IDE controllers.'
     Option 'Disabled' = 0x0 Flags 0x0 Key 0x0
     Option 'Enabled' = 0x1 Flags 0x1 Key 0x0
    End One Of
   End If 
   Grayout If
    FALSE
    One Of [0x39<1>] 'SATA Native Support'
    \Help text: 'Enabling SATA Native Support will improve the HDD performance. Disabling SATA Native Support may be necessary when a legacy OS is used.'
     Option 'Enable' = 0x1 Flags 0x1 Key 0x0
     Option 'Disable' = 0x0 Flags 0x0 Key 0x0
    End One Of
   End If

After doing the same tell if you have got IDE Controller and SATA Native Support option into System Configuration menu.

According to me one cannot disable AHCI option or switch to IDE in the BIOS of the laptop which you are using. However one can get the requirement by modding the BIOS. Another thing is you should contact the HP technical support and I am hoping that they will help you to fix the matter of yours.
