Windows 10: AHCI vs regular Native IDE

Night Hawk, you only need the F6 drivers if you are installing to a raid array. If installing in AHCI, Windows has it's own implementation of AHCI drivers since Vista that work pretty well.

 

Well 7 is running into BSOD favorites and finding "device inaccessible" errors when gong to change the Native IDE to AHCI. As for both AMD and Intel you can be sure they sit together in conferences discussing how to keep standards going between the two and see to it that drivers are available. MS would be on their case in a hurry if not!

But going by what Gigabyte had at their support site was for a floppy disk type F6 option you would have previously seen at the time 7 was installed. As I recall I thought that was left behind years earlier with XP not 7?! And when looking through the Device Manager there isn't any Sata controller item even when showing all hidden devices to have browse for the drivers once those are unpacked. The support site offers both the RAID and AHCI downloads separately but with both needing the F6 option?!

I have to wonder about how to slipstream them into an installer of some type since both 64bit Ultimate on one build and Pro on the other both run into the fast and furious blue screen to simple message of not finding the bootable device being accessible. 10 of course is three versions newer and seeing the advantage of covering more hardware configurations as well as including a larger variety of generic drivers due to the now multiple platform OS we are looking at. In fact 10 never even noticed the change while 7 did!

 

see if you can find out what msahci.sys is.

 

That's a reg value you have to modify one of the DWord values for. That and the pciide are changed from 1 to 0 being the binary on'off switch in 7. In 10 don't bother to look for the MSahci value since it isn't there to find to begin with.

Following the setting change in the bios 10 simply loaded up as it has been doing for the last two weeks as if nothing had been changed while the values changed in 7 still run into the stall on start up issue. With 7 a restart after the two values saw the change should have seen the correct drivers sought out by Windows automatically which didn't happen where you restart the system a few times before going into the bios to make the change there. No Go here! *Redface

 

For AMD users (old laptops) from 2009 to 2013 models

I managed to get my old G6-1d48dx running smoothly on Windows 10 using this method!
(Please note that not all G6's can use this method and you should proceed at your own discretion!)
Steps to fix this error:

1. Download BIOS revision F.46 (You most likely have F.48 or F.49) if it is available for your laptop (Go to the Windows 7 Drivers section>BIOS>Previous Versions).

2. Install the older BIOS

3.After installing the older BIOS, your laptop most likely will not boot fully, it should give a BSOD and restart, let it do this twice and the third time it should attempt to perform a startup repair THIS WILL (AND SHOULD) FAIL!

4. After startup repair fails, click on "Advanced Options"

5. Click Troubleshoot>Advanced options>Start-up settings

6. Click restart

7. When you see the start-up settings screen, press "4" on your keyboard

8. You will then boot into safe mode, do not log into your computer when presented with the login screen, just press Power>Restart

9. You should be able to fully boot into Windows now

10. Put the computer to sleep and wake it, it should now fully work! The issue was that the newer BIOS breaks the way Windows 8/10 read the SATA configuration and downgrading the BIOS fixes it.

Enjoy!

there's no need to edit registry or going to BIOS because 90% of laptops are set to ACHI SATA as default settings
i hope this one helps let me know!

thanks
