Hello there. I have couple question. I tried google but was not successful.
I have Windows XP, BIOS set to RAID, 2 HDD, running Intel RST (Latest driver). and running fine.
Mobo is Gigabyte GA-EP35-DS3R (P35 / ICH9R)
I need to change 2 HDD RAID to 1 HDD AHCI mode.
I managed cloning 2 HDD RAID volume to 1 HDD, and Windows XP starts just fine under BIOS set to RAID.
But when I change BIOS to AHCI mode, I get 0x7B BSOD.
These are my question.
(1) How do I change Windows XP to RAID mode to AHCI mode?
(2) Any disadvantage if I keep using RAID mode in 1 HDD configuration?
Thank you!
Matthew K

Since no one answer to my questions, I googled more and tried to fix myself and I managed to fix 0x7b BSOD.
Here is what I did.
I basically followed his advice.

I had iaStor.sys in RAID mode, my registry was like this.
