Windows XP unable to install on HP ProBook 4520s in AHCI mode

I have purchased a new laptop, HP 4520s, and cannot install the Windows within ACHI mode. Very odd thing. I have tried to realize all over the place the right drivers, no consequence...while used the nLite and running Windows install another time with ACHI mode (settled inside the BIOS) I just got blue screen following the error message saying: Cannot find the ACPI.SYS.. Push any key to restart.

It is a problem sata raid drivers not available.. On the xp cd. XP does not recognize your hard drive if it is a sata, it needs the drivers. Either you redo a xp cd with Nlite which preempt to add sata raid drivers, or you look in the bios if you can set the mode to disable raid sata ahci mode or ide.

Yes. That sounds weird since it's an xp sp3 but tries to load the sata drivers for your motherboard (on the cd driver) they may be well specified and those of the Windows CD does perhaps not. Early in the install of xp it loads a lot of drivers and you can tell it to load a driver by pressing F6 at a time when it Write. Finally, I see that it is possible that the generic drivers for xp does not work on your SATA bus

The default setting in the BIOS of the P5B Deluxe is the SATA controller in IDE mode. The Board does so as if the SATA drives would be quite normal IDE drives. This has the advantage that the compatibility is better, because all operating systems recognize the drives with no problems during installation. The disadvantage is that SATA features such as Native Command Queuing (NCQ) and hot-plug (plate change during operation) in IDE compatibility mode is not usable.

On motherboards equipped with interfaces for hard drives Serial ATA , you can choose from the BIOS if the interface for the hard disk has to work in emulation IDE (the standard used before the arrival of SATA) mode AHCI (Advanced Host Controller Interface) mode, or RAID . In theory, the choice should be made before installing the operating system, in fact, changing this page after installation, Windows will not start pointing out the absence of 'hard drives. Because this method requires special drivers to hard to recognize the Windows setup.

For those interested, I used nLite (XP utils Personal) to add the AHCI drivers for SATA controller to install various direct AHCI

Such operation is not necessary to have windows with the disk in AHCI mode, install windows in IDE mode, and when it is operational, install the motherboard driver (nforce), then go to device manager, looking for in the list Nvidia disk controller Ide, Vbase you to their properties, update the driver tells you that you have a disk, and select the driver that is in the folder C: / nvidia / nforce / SATA on your hard drive, install normally completed it, restart, the bios, change to AHCI mode and start windows normally, now really in devices manager, the disk works in AHCI mode

The way AHCI (Advanced Host Controller Interface) controls the advanced features of SATA controller, including NCQ (Native Command Queuing). NCQ mode is a way of finding its own data only SATA disks (that support it) that allows faster access to information, since instead of accessing the information in the search order that we give, accessed in the order in which is recorded in the hard disk surface, minimizing the movement of the playhead, waiting and system wear.

In your case you have the mother as manufactured, IDE support is what makes "emulate" an IDE for the operating system to install think you have an IDE and SATA, so you cannot use the NCQ of the SATA for the movement of large volumes of data is important.
