Enabling IDE and RAID mode on ASUS X555LB.

In the BIOS the only option is AHCI but how can I import IDE and RAID options to the BIOS? And How can I add Gen4 cpu for the Last hardware for Windows XP?

@XPLAKE8175 - I can switch your SATA modes options from the one with AHCI only, to the IDE, AHCI, RAID one.

As for Gen4 CPU, I have no idea what that is, you need to give specific CPU model, but in general on that question I also have no idea what you mean when you say >> Last hardware for Windows XP

If you want mod BIOS for the IDE/RAID options, you need to first send me a dump of your BIOS region via FPT, and then you will need to unlock BIOS Lock using Grub and setup_var, after that you can flash in the mod BIOS I send you
Here is guide on unlocking BIOS Lock, you can start at step #6 because I will give you the info you need after link
[GUIDE] Grub Fix Intel FPT Error 280 or 368 - BIOS Lock Asus/Other Mod BIOS Flash

Rename your .efi file to >> Shell.efi
BIOS Lock Variable to unlock >> 0xB0
SMI Lock variable to unlock >> 0xAF

So at grub prompt you will type the following, one line at a time, enter between each.
setup_var 0xB0 0x0
setup_var 0xAF 0x0

Here’s how to send me a FPT Dump of your BIOS region - Check BIOS main page and see if ME FW version is shown, if not then download HWINFO64 and on the large window on left side, expand motherboard and find ME area, inside that get the ME Firmware version.
Once you have that, go to this thread and in the section “C” download the matching ME System Tools Package (ie if ME FW version = 10.x get V10 package, if 9.0-9.1 get V9.1 package, if 9.5 or above get V9.5 package etc)
Intel Management Engine: Drivers, Firmware & System Tools

Once downloaded, inside you will find Flash Programming Tool folder, and inside that a Windows or Win/Win32 folder. Select that Win folder, hold shift and press right click, choose open command window here (Not power shell).
At the command prompt type the following command and send me the created file to modify >> FPTw.exe -bios -d biosreg.bin

Right after you do that, try to write back the BIOS Region dump and see if you get any error, if you do show me image of the command entered and the error given >> FPTw.exe -bios -f biosreg.bin

If you are stuck on Win10 and cannot easily get command prompt, and method I mentioned above does not work for you, here is some links that should help
Or, copy all contents from the Flash Programming Tool \ DOS folder to the root of a USB Bootable disk and do the dump from DOS (FPT.exe -bios -d biosreg.bin)
