Thanks for joining the chipset community.
I understand you have some questions in regards to Intel® Rapid Storage.
I will answer your questions as best I can, that way you can continue with your configuration.
Please bear in mind that starting from Windows 7, SATA (RAID or AHCI) drivers are already included on the operating system as part of the driver package that way you can set the system as AHCI or RAID when installing the operating system at once.
Intel recommends installing Intel® Rapid Storage software after installing the operating system. This way pre-OS driver gets updated to the latest version.
The driver is available with file name: SetupRST.exe
About BIOS, there is nothing that changes BIOS configuration when loading operating system. If you are going to perform dual boot configuration, you need to install just SetupRST.exe on every operating system. Again, this will update existing AHCI or RAID driver.
I hope this help.
Thanks Alan for the reply. What I understand from your answer -
1. The pre-OS driver is needed only for older versions of Windows (may be for Windows XP). So I don't need to pre-load the driver at all.
2. Even if I use the pre-OS driver I should install the post-OS one after installing the OS so that it can be updated to the latest (plus I'm getting the IRST Configuration application).
3. I actually meant any possible BIOS/Firmware overwriting/change when I load the pre-OS driver during the installation of the second OS, not when loading the OS. But I presume since it's a driver, each OS will have their own copy/version and nothing gets overwritten at BIOS/Firmware level.
Please correct me if I'm getting anything wrong. Thanks a Lot.
Thanks for coming back to the communities.
Yes, that is called F6 driver and it was needed for Windows XP installations (RAID or AHCI). Exactly, currently you do not need F6 drivers.
Exactly, you will need to install SetupRST.exe after your operating system has been installed.
Pre-OS drivers will not make any changes at BIOS level.
