Recently, due to my mother being a bit nuts about her old computer, my father had to swap components around once more. I ended up with a newer motherboard, slightly faster CPU and twice the memory I used to have, but due to the fact I'm running Vista, a full reinstallation would take ages to preform, which neither of us wanted to go through. So, we tried to make my current system adapt to the newer board. While it as a bit risky and not without problems, the attempt turned out mostly successful, because the Intel chipset was somewhat compatible (the old one was P35, while I now have P45). Now, the only problem is that enabling AHCI (which I used on the previous board) causes BSOD to occur and prevents system from starting. We eventually tracked the problem down to old AHCI drivers, which were still from P35 and didn't update (at least, not from the installation disk included with the motherboard). After a few futile attempts to get them to update, I decided to ask here for help.
Does anybody here knows how to remove or replace the old drivers, or any other way to get AHCI working without full reinstallation?

If you're changing the motherboard, you'll want to reinstall OS. Installing Vista can't be that hard or involved. I'm sure this isn't what you want to hear, but you're just asking for trouble if you keep the same install.
-
Installing Vista isn't, by itself, problematic. Getting something usable out of it, on the other hand, is. It took us the entire day of hard work to get it to run properly. So it's not an option, we don't have this kind of time anymore. I just need to somehow get rid of old AHCI drivers,everything else seems to work.
-
switch ahci off
install ahci drivers
switch back to ahci
-
That's what we tried, it didn't worked. I wish it was that simple.
The problem is, the installer doesn't install AHCI drivers for P45, since it detects those for P35. I need a way to remove old ones and the install a new set.
-
format the drives and start over, youd be done by now. its a thing that would have taken an hour for me to do.
-
This might be a stupid question, but is there any particular reason you can't just use IDE mode or something? That's what I did when I just switched mobos (P55 to Z68 chipset). BSOD'd on startup, then switched to IDE mode from AHCI and went on my merry way.

Astronomiya has a point ahci isnt all that benchmarks show if doesnt make much difference
ps: have you tried device manager uninstall (perhaps even scan for hardware changes)

pps: if it works and you reboot and you get new hardware detected cancel it and run the driver setup program
another ps: does you mboard (what make and model) have more than 1 sata contoller (mine has 3) you could move your drives onto them/it
ps: am I right in thinking the p35 uses ICH9 and p45 uses ICH7R if so you could download the driver here :

and remove any refernce to the ICH9 from IAAHCI.inf and IASTOR.inf

Thanks. It turned out, we were using ICH10R (the correct one), but due to the tricky way this motherboard handles hard disc management, we ended up misconfiguring it (and losing CD drive in the process :)). Looking into Device Managed helped in cleaning this up. Now everything's working.

glad to hear it,
Ive just added a new hdd and while in the bios checking it was recognized ok I noticed that my previous hdd was set to standard ide (my dvd-rw is also sata)
so i set it to ahci and CDBurnerXP: Free could no longer detect the dvd drive (turns out it doesnt like ahci) so I had to replace it with burnaware free
