Hi Fernando,
you’re my last hope.
I tried for weeks now to get the XP-installations from my old (and sadly dead) machine (ASUS M2N32WS Professional) booted on the new machine (ASUS Z170-A). These disks were NOT installed in AHCI-mode, so I get a 7B BSOD.
Are there any working XP AHCI-drivers for this board ((Intel 100/C230 Chipset family), and if so, how do I install them into the registry? I downloaded the “>Universal 32bit Intel RST AHCI+RAID driver v11.2.0.1006 mod+signed by Fernando<” and tried several ways to integrate them, but nothing worked. It should be the VEN_8086&DEV_A102. Any ideas how to make a working reg-file?
Regards and thanks in advance
Fussel
I forgot: The BIOS/UEFI of the new machine doesn’t offer the option to switch off AHCI 
@Fussel :
Welcome at Win-RAID Forum!
Yes, it is the “Universal 32bit Intel RST AHCI+RAID driver v11.2.0.1006 mod+signed by Fernando”, which has already been downloaded by you.
You have to integrate this driver into an original Windows XP SP3 image according >this< guide.
Good luck!

Fernando, thanks for the quick answer.
Unfortunately, the guide you mentioned (which I had read before) only deals with new installations. My Problem is getting EXISTING installations to boot on the new board. So I need some kind of reg-file to integrate the drivers into the registry. I can attach to the registry via an old ERD-Commander, but what to write into it?
Any ideas?
As I understand, XP has no generic AHCI drivers, and so it looks impossible to switch existing installation from IDE to AHCI mode on the fly. Why can`t you switch SATA controller into legacy IDE mode?
Because, as I said in my first post, the UEFI of the board (ASUS Z170-A) doesn’t offer the option to switch off AHCI and change to legacy IDE.
@Fussel :
As mbk1969 already has written, you have to do a fresh XP installation with integrated Intel AHCI driver, if you want to run XP on your system, whose Intel SATA Controller cannot been set to IDE mode.
Question: How did you get XP installed at all? In RAID mode?
By the way: Your problem has nothing to do with the topic of this thread. If you should have further questions, please post them into a better matching thread or start a new one with a meaningful title.
@Fernando :
Sorry for having posted into the wrong thread, so please delete it or move it as you see fit.
Btw, I finally succeeded in booting up an old XP installation (using your drivers), only to have it freeze up trying to plugplay the PCI-to-PCI-bridge, so further research is neccessary.
Done!
That is fine.
