Windows 7: Convert Sata Mode from AHCI to ISRT without reinstalling OS

Convert Sata Mode from AHCI to ISRT without reinstalling OS

Hello All,

On One of my dell laptops....

I tried Installing OS using IRST mode on in Sata Operations in BIOS.. but OS wasn't able to detect disks while Installing it. Even diskpart showed no disk available.

So I installed OS after changing sata mode back AHCI ..

I have a mSATA of 60GB and an HDD of 1 TB ...
OS got installed on 1TB hdd....

But the now the OS is not utilizing the SSD of Cache management.
If I change the sata mode back to Intel Smart Response tech (ISRT) the Computer goes NO BOOT
Is there a way I can change ISRT back ON in BIOS without Reinstalling OS..

Any help would be appreciated.

I`m no expert on those drives, but, I don`t think it`s gonna use the cache if you installed windows on the hard drive. Is it 2 separate drives ?

As far as the other, I`m not positive but you usually can`t switch from AHCI to the other once you install the OS, but then I`ve only seen 3 options in a bios, AHCI, IDE or Raid.

Others with the option you speak of will have to answer on that.

NO Problem resolved it by myself... Needed a Lettle tweak in Regedit..
FYI.. you can switch from AHCI to other modes (if available) even after installing OS..
Please google IRST and ISRT

SATA that support AHCI and RAID mode only
I have an Asus M4N78 PRO. There are 6 Sata connectors but 2 support AHCI and RAID mode only. (4 red and 2 black) I have 3 harddrives and 1 DVD connected in the 4 red ports. Maybe I'm going to buy a SSD to speed up my PC :) Is it possible to use one of the black sata ports if I enable AHCI....
